This study endeavors to establish an economically viable pathway to derive porous carbon materials from MB. Simple pyrolysis of MB resulted in a MB-based carbon (MBC) characterized by a negligible open-pore structure. However, subsequent water washing transformed it into a porous material. N2 adsorption tests revealed that the pyrolysis temperature and washing method substantially influenced the specific surface area (SSA) and pore volume of the MBC. While the catalytic activation function of elements inherent in MB, such as Na, Mg, K, Ca, and Cl, rendered MBC inherently porous, these elements also induced an initial pore-blocking effect that concealed the pores. Subsequent washing with water nearly eradicated Na, K, and Cl from MBC, making a number of the concealed pores accessible. Furthermore, a CO2 aeration washing method effectively eliminated Mg and Ca elements from MBC, resulting in a substantial increase in SSA (>1000 m2/g) without the need for additional activation processes. Based on an understanding of the dual role of the elements naturally present in MB, this study demonstrates a potential strategy for environmentally friendly and cost-effective porous carbon production.. |
| 2. | Da He, Ryo Sakai, Koji Saito, Toru Kato, Chika Kosugi, Hyeonseok Yi, Takaaki Shimohara, Koji Nakabayashi, Seong-Ho Yoon, Jin Miyawaki, Facile elimination of alkali and alkaline earth metals from marine biomass-derived carbon for comparative analysis of chemical composition with standard coal and coke, Carbon, 10.1016/j.carbon.2023.118570, 216, 118570, 2024.01, Pyrolysis of marine biomass (MB) to create marine biomass-derived carbon materials (MBCs) for industry is a sustainable solution. In this study, we systematically examined pyrolysis processes and performed elemental composition analyses of MB and MBC. The results revealed that MBC contained 12.5–25.5 mass% of alkali and alkaline earth metals (AAEMs). As the pyrolysis temperature increased, some of these AAEMs underwent physical phase changes. Subsequently, we applied CO2 aeration washing for the first time or low-concentrated acetic acid washing to eliminate AAEMs from MBC, reducing potential hazards in the future industrial application. Characterization results suggested that both post-processes effectively removed AAEMs from MBC, reducing the average content of Na and K to 0 mass%, Ca to 1.4 mass%, and Mg to 1.9 mass%. The Cl content was also reduced to 0.1 mass%. After removing AAEMs, the final carbon content of MBCs was as high as 90.8 mass% (dry ash free basis) with a minimum ash content of 6.4 mass% (dry basis) according to ultimate analysis. Comparison with commercial coal products showed that carbon contents were superior and ash contents were lower than those of most coal samples, suggesting that the treated MBCs are of sufficient quality for the carbon cycle industry.. |

Although chemically activated carbon with highly developed pore structures exhibits good ethanol adsorption, the associated high production costs inhibit its practical application as an AHP adsorbent. Moreover, although physical activation can produce inexpensive activated carbon, the limited pore development limits the ethanol uptake. Recently, we developed a pressurized physical activation method that can produce activated carbon with a well-developed pore structure and characteristic pore size distribution. In this study, we investigated the applicability of the pressurized physically activated carbon as an adsorbent in activated carbon–ethanol AHP systems. Because of the large number of pressurization-induced pores of appropriate size, the pressurized physically activated carbon showed effective ethanol uptake comparable with that of chemically activated carbon on a weight basis. Furthermore, on a volume basis, the pressurized physically activated carbon, with a high bulk density, showed much higher effective ethanol uptake than chemically activated carbon. These results confirm the potential of the pressurized physically activated carbon as a relatively inexpensive high-performance adsorbent for AHP systems with ethanol refrigerants.. |

| 16. | Hyeonseok Yi, Koji Nakabayashi, Seong-Ho Yoon, Jin Miyawaki, Pressurized physical activation: A simple production method for activated carbon with a highly developed pore structure, Carbon, 10.1016/j.carbon.2021.07.061, 183, 735-742, 2021.10, [URL], 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.. |

The method was experimentally validated using wide-pore-selective hydrophilization. n-Nonane was physically adsorbed for pre-masking, followed by room-temperature ozonation for surface modification. This process was used to introduce surface functional groups into wide pores, while leaving narrow pores intact. This study facilitates the development of new porous carbon materials with different surface properties that depend on pore size. This flexible strategy can be employed in conjunction with various molecular masking agents and surface-modification methods.. |

Activated carbons produced from local waste biomass have been attracting considerable attention in adsorption technology due to their unique properties and sustainability. However, their limitation in water vapor uptake hinders the practical application of this material. In this work, acorn nutshells were utilized as a base material to produce activated carbon. Air oxidation was performed as a versatile and low-cost technique to enhance the material's properties and water adsorption capacity. By applying air oxidation as a post-treatment during material production, the amount of active functional groups and the water adsorption on activated carbon has been successfully enhanced. From the theoretical calculation, it is found that activated carbon–water working pairs shown promising performance to be used for adsorption thermal energy storage applications. The adsorption of water vapor on the post-treated-activated carbon releases the isosteric heat between 2400 kJ/kg to 2500 kJ/kg. Moreover, this study's working pair can be driven by a temperature of less than 50 °C. From the results, it is confirmed that by controlling the adsorbent's surface properties, activated carbon–water working pairs can be a promising way to provide alternative material and reduce the energy demand for driving the system.. |

In this study, activated carbons were produced from dead camphor leaves using two-step methods at different preparation temperatures. The characterization results revealed that the prepared activated carbons have a surface area of 700 m /g, with 75% of microporosity. The water vapor sorption study reported that the water uptake of camphor leaf-based activated carbons was strongly affected by the pore properties of the materials. Moreover, from the water adsorption kinetics, it was observed that the rate constant of adsorption was varied at each relative pressure, which can be assumed that the water adsorption mechanism is different at each relative pressure. From these results, it was revealed that the prepared camphor leaf-based activated carbons have a promising ability to adsorb water vapor from humid air. 2. |

Therefore, capturing/storage and utilization of CO 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 CO 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 N adsorption/desorption data. It is praiseworthy to elucidate that the highest surface area and pore volume for biomass-derived ACs (BACs) are obtained 2927 m g and 2.87 cm g , respectively. CO 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)/CO pair shows the highest adsorption uptake as high as 1.791 g g (excess adsorption) and 2.172 g g (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 CO reported in this study are the up-to-date benchmarks. The results show that novel BACs/CO pairs possess remarkably high adsorption performance, which will contribute towards the advancement of various adsorption-based technologies. 2 2 2 2 2 2 2 2 2 −1 3 −1 −1 −1. |

This research was an effort to over-come environmental problem caused by battery waste by converting into adsorbent for methyl orange (MO) that frequently used by textile industries. The prepared powder was then analyzed to understand its characteristic peaks, crystallinity, and to compare the properties with other carbonaceous forms, i.e. a commercial Carbon Paper (CP), and a commercial meso- carbon micro-beads (MCMB). The analysis found that CWP is dominated by graphitic carbon. An adsorption experiment was then conducted to study their adsorption ability to methyl orange solution. The result found that those three carbona-ceous materials have the ability to adsorb methyl orange with different activities. MCMB has the high-est adsorption capacity of 0.197 mg.g-1. Meanwhile, CWP and CP show adsorption capacity of 0.066 mg.g-1 and 0.062 mg.g-1, respectively. Methyl orange adsorption on CWP and CP were under second or-der, which means the adsorption could be four times faster as the MO solution doubled. Moreover, the rate constant of MO adsorption on CWP is 8×10-4 min-1, which was higher than the rate constant of MO adsorption on CP. It confirmed that the CWP can be used as a promising adsorbent for dye waste wa-ter.. |

To develop spinnable pitches, four different tars were produced and hybrid pitches were synthesized using different PFO blending ratios and bromine amounts. Results showed that PFO improves spinnability and pitch yield considerably. Furthermore, pitches with the same softening point (S.P.) were produced from different precursors and spinning, stabilization and carbonization were performed to produce general-performance carbon fiber (CF). In order to explain the structure-property relationship of the products, mechanical, morphological and chemical characterization were done by TOF-MS, elemental analysis, 13C-NMR and SEM-EDX. Thus, a comparison between the characteristics of CFs was made disregarding the S.P.s and more insight into the effect of EBO was gained. Mechanical properties of CFs found to be reasonable, considering typical tensile values of IP-based CFs.. |

The FIB irradiation led to local amorphization of the crystalline structure of the CNF. The in situ measurement was improved by correcting for the effect of the scattered ions on the sensor. The low effective thermal conductivity of the pristine CNF (similar to 39 W/mK) resulted from the anisotropic structure made of many individual graphitic fibers. The first FIB irradiation decreased the thermal conductivity by approximately 3.2%. This relatively small decrease is attributed to the structure of the CNF consisting of many individual fibers, with some fibers remaining pristine even after the FIB irradiation. Analysis using a thermal-circuit model suggested that the thermal transport in the CNF could include a ballistic feature of phonons in the micrometer range. Our proposed in situ thermal measurement method can be extended to the study of thermal transport in various structurally modified nanomaterials. (C) 2019 Published by Elsevier Ltd.. |

Two biomass sources: (i) Waste Palm Trunk (WPT) and (ii) Mangrove (M) are employed to synthesis activated carbons with huge surface area by chemical activation with potassium hydroxide (KOH). Thermophysical characteristics of the derived activated carbons namely thermal conductivity, particle size distribution, pore size distribution, surface area and pore volume are assessed. The total surface area of WPT-derived AC and mangrove-derived AC are found to be as high as 2927 m g and 2924 m g , respectively. The adsorption capacities of the synthesized biomass-derived ACs for ethanol are evaluated for assorted temperature and pressure conditions. It is observed that WPT-AC shows an ethanol uptake of 1.90 kg kg whilst the M-AC can adsorb up to 1.65 kg kg . The isosteric heat of adsorption associated with the present adsorbents/adsorbate (ACs/ethanol) calculated at different coverages showed only marginal difference. For a typical operating condition of adsorption heat pump, both biomass derived ACs showed similar net ethanol uptake which is significantly higher than the net uptake of commercially prevalent Maxsorb III AC. 2 −1 2 −1 −1 −1. |

A magnetic suspension adsorption measurement unit has been used for the experimental measurements. Four well-known adsorption isotherm models have been employed to fit the experimental data whilst two classical adsorption kinetics models i.e. Linear driving force (LDF) model and Fickian diffusion (FD) model are used to predict the experimental kinetics data. Among the four isotherm models Dubinin Astakhov (D-A), and Tóth equations agree well with the experimental uptake data for both ACs. The diffusion time constants are calculated at each adsorption temperature for WPT-AC/ethanol and M-AC/ethanol pairs. Moreover, activation energy and pre-exponential constant have been determined from the Arrhenius equation.. |

In this study, the differences in the pore development mechanisms between physical and chemical activation processes for AC preparation were studied from a structural point of view, based on the microdomain structure model. Phenol resin-based spherical carbon was used as the starting material. AC preparation via potassium hydroxide (KOH) activation (chemical activation) did not induce noticeable changes in the particle or microdomain sizes, despite the abundant development of pores. On the other hand, ACs produced via steam activation (physical activation) showed remarkable reductions in both particle and microdomain sizes, depending on the activation temperature. Considering the differences in activation yield and degree of developed porosity between chemical and physical activations, we concluded that, in the case of KOH activation, pore development homogeneously progressed overall for all microdomains consisting of carbon particles without apparent morphological change; however, steam activation caused inhomogeneous gasification from the outer surface of the carbon particles and microdomains. For this reason, KOH-ACs showed higher yield and superior pore development.. |
