Hiroki Shimanoe, Takashi Mashio, Taisei Tomaru, Seung-Jae Ha, Young-Pyo Jeon, Koji Nakabayashi, Jin Miyawaki, Seong-Ho Yoon, Understanding mesophase pitch from a lyotropic liquid crystalline perspective, Carbon Reports, 2-1, 2–22 (2023), https://doi.org/10.7209/carbon.020105, 2, 1, 2-22, 2023.03, This review explores recent research regarding mesophase pitch (MP). Spinnable mesophase pitch (SMP) was used as a model pitch for MP in all experiments. We explain some phenomenological results of the lyotropic liquid crystalline properties of the SMP, which show that the MP behaves as a typical lyotropic liquid crystal. The mesogenic and solvent components of SMP are defined. We define the threshold concentration (TC) as the minimum amount of mesogenic component necessary for SMP to achieve 100 vol% anisotropy. We also report the TCs of various SMPs and discuss the effects of the solvent
component. Concerning the identity of the mesogenic component, we discuss quantitative correlations between the size of the layered molecular stacking units and the anisotropic content of the SMP. Research has shown that a layered molecular stacking unit larger than a specific size corresponds to the mesogenic component of the MP. We discuss a novel method for the manufacture of SMPs using our understanding of MP as a lyotropic liquid crystal, which comprises thermal mixing of optimal amounts of the mesogenic and solvent components that were prepared separately under different conditions. This method enables the properties of each component to be optimized without involving a costly hydrogenation process. Finally, we discuss how this approach can be used to increase SMP yield by modifying the contents of the anisotropic mesogenic and
solvent components.. |

Here, we prepared an environment-friendly uniform N-rich narrow micropore activated carbon, for the removal of formaldehyde, based on steam activation and N-rich with chitin as the starting material. A sample carbonized at 500 °C and steam activated at 800 °C (CAC800) showed a reasonable yield (55%) with uniform and narrow micropores without mesopores but having a balanced nitrogen functionality. CAC800 possesses outstanding formaldehyde removal capabilities under both dry and wet (humidity 45%) conditions. In addition, when compared with commercial activated carbon materials, we clearly demonstrated that the existence of high nitrogen content with uniform and narrow micropores simultaneously removed formaldehyde, effectively.. |

In this study, activated carbon with both specific surface area and mesopores developed at the same time was prepared by preliminarily oxidized petroleum coke with hydrogen peroxide and then activating it with KOH. Hydrogen peroxide used for preliminary oxidation penetrates deep to the inside as well as the surface of petroleum coke to increase reactivity upon activation, forming pores to the depth of petroleum coke to create high specific surface area activated carbon with developed mesopores. Activated carbon prepared by preliminarily oxidized petroleum coke had high specific surface area and mesopores. In particular, OMC-35 had a specific surface area of 3032 m2/g and the highest mesopores of 0.82 cm3/g. As a result, OMC-35 had an excellent capacitance of 196.9 F/g at a scan rate of 5 mV/s. In addition, OMC-35 showed a salt adsorption capacity (SAC) of 19.5 mg/g and excellent desalination performance with a salt removal efficiency of 98.5 % in 250 ppm of NaCl solution.. |

SMP was found to be a specific solution consisting of mesogenic and solvent components, and the mesogenic component was composed of a cluster unit of (002) stacked molecular sheets. The anisotropic texture of SMP was strongly correlated with the height of (002) molecular stacking. When the concentration ratio of the mesogenic component to the solvent component was higher than the threshold concentration, the SMP always had 100 vol% anisotropic texture and a similar or larger number of stacked (002) sheets compared with its mesogenic component in both the solid and molten states. The solvent component, in both lamellar and hexagonal phases, assisted orientation of mesogenic molecules and rearrangement of mesogenic cluster units, thereby inducing a higher degree of graphitization than that of the solvent-free mesophase pitch. A schematic phase model of SMP was proposed based on a lyotropic liquid crystalline system and a hierarchical domain model.. |

Atmospheric residues (ARs) with different compositions were hydrotreated in two plug-flow reactors in series to study the reactivity of various species over the commercial catalysts at the molecular level. A 15-T Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometer equipped with atmospheric pressure photoionization (APPI) was applied to determine the molecular composition without chemical derivatization. Here, we examined the changes in bulk and molecular composition of two different ARs. The catalytic reactivity of the ARs was determined with respect to the relative abundance of the double bond equivalent (DBE) distribution dependent on carbon number for each class, such as hydrocarbon, sulfur, and nitrogen species. Reactivities and reaction routes of hydrocarbon, sulfur, and nitrogen species were discussed in detail at the molecular level.. |

In contrast to the solvent extraction process employing expensive solvents, a low-cost centrifugal separation method facilitated the reduction of loss due to the pitch purification and an overall yield increase. The coal tar pitch purified by centrifugation and subsequently co-carbonized with pyrolysis fuel oil improved in spinnability. Moreover, the resulting spinnable pitch had a softening point of 250◦C. The obtained carbon fibers were heat-treated at 1000◦C for 5 min, resulting in a tensile strength of approximately 1000 MPa and an average diameter of 9 µm. In this study, we present an effective method for obtaining low-cost general-purpose isotropic carbon fibers. . |

Volume 102, Pages 321 - 326 25 October 2021, 10.1016/j.jiec.2021.07.014, 102, 321-326, 2021.10, The effect of pore size on the response characteristic of an electric double layer capacitor (EDLC) was closely examined. A series of phenol-resin-based activated carbon (AC) samples was prepared as average pore size from 0.94 to 1.68 nm by KOH activation by varying the activation temperature and KOH/carbonized phenol-resin ratio. The impedance properties of pouch-type EDLC cells prepared using AC samples were evaluated by applying an alternating current at 3 V between 10 mHz and 100 kHz for confirming the response characteristic. The cell based on the AC with a largest pore size (1.68 nm) showed fast response frequency, and had a high dielectric relaxation time constant as calculated from the response frequency value. The AC with the largest pore size, which consisted of both micropores (>1 nm) and mesopores (2–4 nm), was confirmed to facilitate extremely low electrolyte-diffusion resistance during the formation of the electric double layer, implying that the large pores lead to fast and stable response frequency. The presented findings suggest that AC with a largest pore size as the electrode leads to superior capacitance and response frequency characteristics in the alternating current than those of an AC with a smaller pore size. . |

Volume 183, Pages 735 - 742 15 October 2021, 10.1016/j.carbon.2021.07.061, 183, 735-742, 2021.09, Activated carbon (AC) is produced by a physical or chemical activation process. Physical activation methods are commonly adopted in industry because of their low production costs, but the insufficiency of activating agent diffusibility into core parts of the particles and microdomains of carbon materials causes a lower activation yield and degree of pore development, compared with chemical activation methods. To increase the activating agent diffusibility and corresponding degree of pore development, we propose a novel pressurized physical activation method. Pressurization afforded remarkable increases in specific surface area and total pore volume of the prepared AC, compared with atmospheric pressure. Additionally, in AC prepared by this method, pore size distribution analysis revealed characteristic development of micropores of about 1.6 nm; such micropores did not appear in AC under conventional atmospheric physical activation. Furthermore, observations of particles and their microdomains showed that pressurization increased the activating agent diffusibility in carbon particles, but not at the microdomain level. This innovative pressurized physical activation can produce AC with highly developed pores (specific surface area >2600 m2/g) and a unique pore size distribution due to the improved activating agent diffusibility in carbon particles.. |

Volume 101, Pages 186 - 194 25 September 2021, 10.1016/j.jiec.2021.06.013, 101, 186-194, 2021.09, For elucidation of the pore structure of super-activated carbon (SAC) based on the micro-domain structure model, a new experiment of inverse approach was designed by ball-mill treatment. The two representative SACs with an ultra-high specific surface area (∼3000 m2 g−1) used Maxsorb-III as a non-graphitizable carbon and M-30 as a graphitizable carbon, which are derived from petroleum coke and meso-phase carbon microbeads (MCMB), respectively. SACs consisting of micro-domains, are destroyed during ball milling due to the weak-interactions between the micro-domains. The formation mechanisms of their intra-particular pores (internal slit-like micropores in micro-domain) and inter-particular pores (channeled mesopores between microdomains) are successfully explained by the N2 adsorption/desorption isotherms, FE-SEM, HR-TEM, STEM, and electrochemical techniques. In addition, their capacitance behaviors using different electrolytes as a probe are clearly matched with the change of micro- and mesopores through the ball-mill treatment. This novel micro-domain structure model for porous carbon materials successfully accounts for critical limitations of the conventional hierarchical pore structure model.. |

Evolution of various heteroatom classes in the asphaltenes during the hydrotreating process was examined, focusing on removing sulfur and nitrogen species from asphaltenes. Various heteroatom classes (CcHh,CcHh-Ss, CcHh-Nn,CcHh-Oo,CcHh-NnSs, CcHh-OoSs, CcHh-NnOo, andCcHh-NnOoSs) in the asphaltenes were analyzed by using Fourier transfer ion cyclotron mass spectrometry (FT-ICR MS) linked with atmospheric pressure photoionization (APPI). According to the changes of their relative abundance, double bond equivalent (DBE), and the carbon number in the hydrotreating process, behaviors of the various heteroatom classes in the asphaltenes during the hydrotreating process were interpreted. Two distinctive differences in heteroatom reduction were observed for two different AR samples, and qualitative evaluation was attempted for providing possible scenarios. © 2021 American Chemical Society. |

Volume 293, 1 June 2021, Article number 120429, DOI: 10.1016/j.fuel.2021.120429, 293, Article number 120429, 2021.06, In order to clarify the effect of blending heavy atmospheric residues (AR) and light AR on reactivities for hydrodesulfurization (HDS), hydrodenitrogenation (HDN), hydrodevanadium (HDV), hydrodenickel (HDNi), hydrodeasphaltenes (HDAsp) and hydrodeconradson-carbon-residue (HDCCR) in hydrotreating process, hydrotreating of the blends from two ARs at different ratios was conducted in a fixed-bed unit at 370 °C under a H2 pressure of 13.5 MPa over a set of commercial HDM and HDS catalysts. The compositions and properties of the two ARs and their blends as well as their hydrotreated products were analyzed and compared in detail. A positive synergistic effect of the blending was found for HDS, HDN and HDCCR, while a negative synergistic effect of the blending was observed for HDAsp, HDV and HDNi. A synergistic effect index (ηi,s) was proposed to describe quantitatively the extent of the blending synergistic effect. The observed synergistic effects can be attributed to change of the aromatics-to-saturates ratio in the blends. In addition, composition and property of the hydrotreated products from the blending feedstocks with different blending ratios were well estimated on the basis of the developed models with an average relative deviation less than 1.5 %.. |

Eliminating the resin-rich layer on the surface of composite bipolar plates turns to be an effective approach. In this work, graphite/resin composite bipolar plates with advanced performance and durability are obtained after surface treatment with cactus-like carbon nanofibers which grow from the catalyst cores and stretch out to form cactus-like structures. Morphology and structure of the carbon nanofibers, as well as the morphology, electrical conductivity, electrochemical properties and charge-discharge performance of the bipolar plates in a vanadium redox flow battery (VRFB) are investigated. Results show that surface treatment with graphitized cactus-like carbon nanofibers significantly enhance the conductivity of the composite plates which reaches as high as 198.7 S cm−1, and the area specific resistance can be reduced to 25.4 mΩ cm2. The VRFB single cell with the modified bipolar plate exhibits very high energy efficiency of 86.28%, at 100 mA cm−2, and shows excellent durability in charge-discharge cycling test. With the superior properties above, composite bipolar plates after surface treatment with cactus-like carbon nanofibers are promising candidates for VRFBs.. |

Three paired samples were successfully synthesized with similar specific surface areas and average pore widths through steam activation (physical) and KOH activation (chemical) processes. Their capacitive behaviors were investigated with their effective charge (β) values through 19F ex situ solid-state NMR and electrochemical methods. Despite their similar pore characteristics, their capacitive behaviors were totally different because of the differences in their surface structures such as the edge-rich for KOH activation and basal-rich for steam activation. The KOH-activated series displayed higher capacitances and β values than those of the steam-activated series due to the existence of an edge-rich surface structure, which induced more effective charging under electrochemical polarization. Additionally, the pore development model (domain theory) through the KOH and steamactivation approaches was discussed by using the β values and chemical shifts by using this 19F ex situ solid-state NMR technique.

Volume 158, March 2020, Pages 922-929, 10.1016/j.carbon.2019.11.082, 8, 922-929, 2020.03, Spinnable mesophase pitch with high pitch yield of more than 50 wt% was successfully prepared using direct bitumen coal extracted fraction through the three-step process of hydrogenation, N2 blowing heat treatment, and thin-layer evaporation. The prepared mesophase pitch was smoothly spun to the fibrous form and could be converted into mesophase pitch-based carbonized and graphitized fibers through the usual oxidative stabilization, carbonization, and graphitization. The prepared mesophase pitch based carbon fibers showed typical random transversal structures with mechanical performances, tensile strengths of 1.83 GPa and 3.00 GPa, Young's moduli of 133 GPa and 450 GPa, and elongation properties of 1.37% and 0.68% after heat treatments at 1000 °C for 30 min and 2800 °C for 10 min, respectively. The relatively high-molecular-weight and well-developed polynuclear aromatic molecular structure of hypercoal is the likely reason for the high mesophase pitch yield. The meaning of each preparation processes, hydrogenation, N2 blowing heat treatment and thin layered evaporation, was discussed in detail. We anticipate that the success of high-yield mesophase pitch manufacturing using hypercoal as raw material will be an important key to innovatively reduce the production cost of mesophase pitch-based carbon fiber.. |

Volume 8, Issue 9, 9 March 2020, Pages 3844-3852, 10.1021/acssuschemeng.9b07253, 8, 3844-3852, 2020.03, The 18th century industrial revolution dramatically changed people's lives and allowed for rapid growth of the global economy. However, since that time, the mass consumption of fossil fuels has resulted in the release of large amounts of carbon dioxide (CO2) into the atmosphere, creating a greenhouse effect and global warming. In turn, global warming poses a serious threat to the workings of society. Thus, the immobilization of emitted CO2 and the development of effective CO2 utilization technologies are currently being investigated toward the development of a sustainable society. This study proposes the manufacture of carbon nanofiber (CNF) materials using CO2 gas as a carbon source. It is expected that this technology will be valuable as a means of recapturing CO2. We report herein the effects of CO2 on CNF growth using CO2 and hydrocarbon gases on simple catalytic chemical vapor deposition (CCVD) catalysts, including Fe, Ni, and Co. Four factors were examined: The effectiveness of the catalyst, the reaction temperature, the CO2 concentration, and the specific hydrocarbons supplied in the feed gas. Use of these techniques will enable one to expect (1) future utilization of exhaust gas emitted from thermal power stations and factories as a carbon source and (2) the future possibility of directly converting CO2 to CNF by utilizing the heat given off by emission from factories and other thermal power-generating facilities as a heat source in CNF synthesis, as well as the future possibility of proposing an effective CO2 utilization system that will be revolutionary in its impact. . |

Pal, A., Uddin, K., Saha, B.B., Thu, K., Kil, H.-S., Yoon, S.-H., Miyawaki, J., A benchmark for CO2 uptake onto newly synthesized biomass-derived activated carbons, Applied Energy
Volume 264, 15 April 2020, Article number 114720, 10.1016/j.apenergy.2020.114720, 264, Article number 114720, 2020.04, To properly address the threat of global warming, there is an urgent need to reduce CO2 from the atmosphere through the development of environment-friendly technologies. Therefore, capturing/storage and utilization of CO2 as a refrigerant for adsorption cooling/heating technologies have been gaining momentum in the last decades. This study focuses on the development of novel activated carbons (ACs) with extremely large pore volume and high surface area from environment-friendly and abundantly available biomass precursor seeking higher CO2 adsorption capacity. Four AC samples are synthesized from the two biomass precursor's namely waste palm trunk (WPT) and mangrove (M) employing potassium hydroxide as an activating agent. The porous properties of the synthesized ACs are investigated from the N2 adsorption/desorption data. It is praiseworthy to elucidate that the highest surface area and pore volume for biomass-derived ACs (BACs) are obtained 2927 m2 g−1 and 2.87 cm3 g−1, respectively. CO2 adsorption characteristics are investigated using a high precision magnetic suspension balance unit at five different temperatures ranging from 25 to 70 °C with various pressures. The WPT-AC (C500)/CO2 pair shows the highest adsorption uptake as high as 1.791 g g−1 (excess adsorption) and 2.172 g g−1 (absolute adsorption) at 25 °C and 5.04 MPa, which is superior to any other ACs reported to date. To the best of our knowledge, porous properties and adsorption uptake of CO2 reported in this study are the up-to-date benchmarks. The results show that novel BACs/CO2 pairs possess remarkably high adsorption performance, which will contribute towards the advancement of various adsorption-based technologies.. |

Volume 10, Issue 1, 1 January 2020, Article number 25, 10.3390/app10010025, 10, Article No.25, 2020.01, The toxic nature of acetaldehyde renders its removal from a wide range of materials highly desirable. Removal of low-concentration acetaldehyde (a group 1 carcinogenic volatile organic compound) using an adsorbent of cellulose-based activated carbon fiber modified by amine functional group (A@CACF-H) is proposed, using 2 ppm of acetaldehyde balanced with N2/O2 (79/21% v/v) observed under continuous flow, with a total flow rate of 100 mL/min over 50 mg of A@CACF-H. The effective removal of the targeted acetaldehyde is achieved by introducing the functionalized amine at optimized content. The removal mechanism of A@CACF-H is elucidated using two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (2D-GC TOF-MS), indicating the efficacy of the proposed acetaldehyde removal method.. |

Pitch precursors were prepared by the chlorination–dehydrochlorination triggered by chlorine radicals originated from PVC; aromatization and poly-condensation reactions occurred by polyene-type radicals from PVC. Radical production and co-carbonization were facilitated by pretreatments of EO through vacuum distillation, bromination, and additional heat treatment. Pitches were prepared by the cocarbonization of pretreated EO and EO containing 20 wt% PVC, and had higher yields and better spinnability than those by simple distillation.. |
