    Methylcyclohexane (MCH) dehydrogenation is essential for the practical utilization of organic hydrides as hydrogen carriers. Selenium (Se) modification on Pt/TiO2 catalysts has been found to be effective for MCH dehydrogenation in our previous research. To determine the effects of Se modification on the reaction, reaction kinetics analysis was performed. The Se modification onto rutile-type TiO2 (STR, STR-100N) before Pt loading (Pt/Se/STR) showed the highest activity, and even a small amount of Se significantly improved the activity. Although the kinetic analysis of Pt/ STR showed that the reaction rate of MCH dehydrogenation decreased at high MCH partial pressures, the reaction rates of Pt/Se/STR and Se/Pt/STR remained the same even at high MCH partial pressures. We found that the inhibition of MCH adsorption onto the catalyst could be prevented by Se modification. This behavior was confirmed by adsorption/desorption evaluations.

  • High-pressure <i>in situ</i> X-ray absorption fine structure measurements for hydrogenation of CO<sub>2</sub> to methanol over Zn-doped ZrO<sub>2</sub>

    Obtaining insights into the active-site structure of a catalyst during high-pressure and high-temperature catalytic reactions is extremely challenging. In this study, changes in the coordination structure of Zn species in Zn-doped ZrO2 catalysts (Zn/(Zn + Zr) atomic ratio = 9%) during CO2-to-methanol hydrogenation (cell temperature = 400 °C, pressure = 9 bars) was investigated using high-pressure in situ X-ray absorption fine structure measurements and density functional theory calculations. The formation of Zn-H species, which are considered the active sites for the reaction, was very limited, with most Zn species existing as [ZnOa] isolated clusters. Additionally, the adsorption of CO2 at the Zr4+ sites near the Zn species induced significant distortions in the coordination structure of the Zn species. This study provides new insights into the catalytic active-site structure.

    To develop an efficient removal process for sulfur species in natural gas and city gas, we investigated the direct decomposition reactions of TBM ((CH3)3CSH) and DMS (CH3SCH3) using zeolite. H-FAU and H-Beta zeolite was effective in direct decomposition of TBM, and showed stable activity even at 150°C. In addition, the reaction mechanism revealed that large pores with three-dimensional channels were important for the TBM decomposition. On the other hand, in direct DMS decomposition, transition metal cation modification onto an H-Beta zeolite was effective, and the reaction temperature could be significantly lowered by the Co ion modification. We have shown that organic sulfur compounds can be efficiently converted by controlling the pore structure and acid properties of zeolite.

    The increasing sulfur content in fossil fuels and the use of biogas as a renewable energy source has highlighted the need for effective desulfurization processes. To remove sulfur species from gaseous resources efficiently, a catalytic process that can convert sulfur compounds to hydrogen sulfide (H2S) at low temperatures is desirable. In this study, electric-field-assisted catalytic methanethiol (CH3SH) decomposition was performed to develop a new system for converting sulfur compounds to H2S at low temperatures. In the thermal catalytic reaction using the Pt/CeO2 catalyst, dimethyl sulfide, which is a byproduct of the reaction, is formed. Compared with the result, applying an electric field suppressed the side reaction. The CH4 and H2S formation rates slightly improved by applying the electric field, suggesting the possibility of controlling the CH3SH decomposition products.

    The use of carbon fiber-reinforced plastics (CFRPs) produces moisture-absorbing CFRP waste, which is usually recycled via thermal decomposition treatment (TDT). However, the oxygen gas generated during heating can hardly penetrate dense CFRPs, resulting in nonuniform damage to the recovered carbon fibers (rCFs) collected from the outer (oCFs) and inner (iCFs) parts of CFRP waste. Herein, TDT was coupled with electrical treatment (ET) to improve the recycling performance of CFRP laminates waste. The tensile strength of the rCFs measured via the single-fiber tensile tests was analyzed using a two-parameter Weibull distribution. Absorbed water was preferentially evaporated from the laminates by Joule heating during ET, resulting in extensive pore formation. Following TDT, the oCFs and iCFs showed nearly identical average tensile strengths because the pores formed by ET served as efficient diffusion pathways for oxygen gas. The proposed recycling technology may potentially be applied to other types of moisture-absorption waste.

    <p>Removal of harmful phenol from exhaust gases emitted during plastic pyrolysis requires an effective catalyst for phenol steam reforming under dilute conditions. Sr addition to Ni/Al<sub>2</sub>O<sub>3</sub> catalyst, a common steam reforming catalyst, improved the catalytic activity for hydrogen production. Ni/Sr/Al<sub>2</sub>O<sub>3</sub> catalyst, in which Ni was loaded onto Sr/Al<sub>2</sub>O<sub>3</sub>, was more effective than Sr/Ni/Al<sub>2</sub>O<sub>3</sub> catalyst, in which Sr was added to a Ni/Al<sub>2</sub>O<sub>3</sub> catalyst. In addition, Ni–Sr/Al<sub>2</sub>O<sub>3</sub> catalyst, in which Ni and Sr were co-loaded onto Al<sub>2</sub>O<sub>3</sub>, showed similar effects but was inferior to Ni/Sr/Al<sub>2</sub>O<sub>3</sub>. The optimum Sr/Ni molar ratio was 1 for the Ni/Sr/Al<sub>2</sub>O<sub>3</sub> catalysts. The effect of Sr addition was to increase the basic adsorption sites of phenol and to modify the electronic state of the reaction site due to the electron donation effect from Sr to Ni. The combination of these two factors improved the catalytic activity.</p>

    In this study, the oxidation of As(III) was examined in a fixed-bed flow reactor filled with a SiO2-supported Pt catalyst, and the reaction kinetics were analyzed. The results of the experiments with different concentrations of As(III) at small W/F suggest that the reaction follows the Langmuir-Hinshelwood (L-H) mechanism. However, at large W/F, the kinetic equations different from the L-H equation were obtained because the O-2 supply to the catalyst surface was rate-limiting. It was also demonstrated using this reactor that As(III) of an equivalent concentration as the mine effluent was almost completely oxidized to As(V) with only dissolved O-2.

    For the development of small-scale desulfurization processes such as fuel cell systems, catalytic decomposition of dimethyl sulfide (DMS) to H2S without H2 addition was investigated using a Co/H-Beta zeolitic catalyst, with its acidity controlled via post-synthesis modification. The protonated zeolite (H-Beta) exhibited little catalytic activity at 400 °C, but Co modification significantly promoted DMS decomposition, with a high H2S yield of 50% observed. The optimum Co amount was equivalent to half of the ion-exchange capacity of the original H-Beta zeolite. While the Co/SiO2 did not display catalytic activity, and thus, the coexistence of acid and Co ion sites is necessary in DMS decomposition. The Co species were introduced at the cation sites of the zeolite, suppressing Co sulfurization, which contributed to the high catalytic activity.

    This study clarifies the thermal reactivity of CH3SH to form ethylene (C2H4), CH4, and CS2. The yield of ethylene was relatively higher (approximately 40%) with 50% selectivity. The long-term reaction characteristics were evaluated to explore the possibility of continuous ethylene production, suggesting that C2H4 was stably obtained for more than 100 h.

    The catalytic properties of conventional H-[Al]-ZSM-5 and gallium-substituted H-[Ga]-ZSM-5 were evaluated in the conversion of methanethiol to ethylene (CH_3SH → 1/2C_2H_4 + H_2S). Dimethyl sulfide (DMS), aromatics, and CH_4 were formed as byproducts on the H-[Al]-ZSM-5 catalyst. The introduction of Ga into the ZSM-5 structure provided a high ethylene yield with relatively high selectivity for olefins. Based on the temperature-programmed desorption of NH_3 and pyridine adsorption on zeolites, the strength of acid sites was decreased by introducing Ga into the ZSM-5 structure. Undesirable reactions seemed less likely to occur at weakly acidic sites. The suppression of the formation of dimethyl sulfide (CH_3SH → 1/2C_2H_6S + 1/2H_2S) and the sequential reaction of ethylene to produce aromatics provided a high yield of ethylene over H-[Ga]-ZSM-5.

  • Voids formation characteristics in typical epoxy-based CFRP laminates during low-temperature annealing in the air or N<sub>2</sub> atmosphere

    The feedstock recycling of carbon fiber reinforced plastics (CFRPs) is typically conducted by either thermal decomposition or dissolution methods for resin separation. A common issue in the recycling processes is that neither oxygen nor solvents can easily penetrate dense CFRP; therefore, penetrating diffusion paths such as voids is expected to improve the separation efficiency. This study presents voids formation characteristics by low-temperature annealing as pre-treatment in typical epoxy-based cross-ply CFRP laminates. The void characteristics were evaluated by electrical treatment and observations after the annealing in the air or N-2 atmosphere. Annealing in air resulted primarily in ply delamination and matrix cracking through slight oxidative reactions. By contrast, annealing in the N-2 atmosphere denatured the epoxy resin, resulting in the formation of voids and swelling that reached the interior of the specimens. The void characteristics could be controlled by the atmosphere in the low-temperature annealing, leading to the penetrating diffusion paths.

    This study investigates the effect of hydrogen sulfide (H_2S) co-feeding on the synthesis of 2,5-dimethyl-1-hexene, 2,5-dimethyl-2-hexene, and 2,5-dimethylhexane (2,5-DMHs), useful compounds, using the dimerization of isobutene under mild pressure conditions. The dimerization of isobutene did not proceed in the absence of H_2S, whereas the desired products of 2,5-DMHs were produced under H_2S co-feeding conditions. The effect of reactor size on the dimerization reaction was then examined, and the optimal reactor was discussed. To enhance the yield of 2,5-DMHs, we changed the reaction conditions of the temperature, molar ratio of isobutene to H_2S (iso-C_4^=/H_2S) in the feed gas, and the total feed pressure. The optimum reaction condition was at 375 °C and 2/1 of iso-C_4^=/H_2S. The product of 2,5-DMHs monotonously increased by an increment of total pressure from 1.0 to 3.0 atm with a fixed iso-C_4^H_2S ratio at 2/1.

    This study focused on evaluating the catalytic properties for the reverse water gas shift reaction (RWGS: CO_2 + H_2 → CO + H_2O ΔH^0 = 42.1 kJ mol^<−1>) in the presence of hydrogen sulfide (H_2S) over a Fe/CeO_2 catalyst, commercial Cu–Zn catalyst for the WGS reaction (MDC-7), and Co–Mo catalyst for hydrocarbon desulfurization. The Fe/CeO_2 catalyst exhibited a relatively high catalytic activity to RWGS, compared to the commercial MDC-7 and Co–Mo catalysts. In addition, the Fe/CeO_2 catalyst showed stable performance in the RWGS environment that contained high concentrations of H_2S. The role of co-feeding H_2S was investigated over the Fe/CeO_2 catalyst by the temperature programmed reaction (TPR) of CO_2 and H_2 in the presence of H_2S. The result of TPR indicated that the co-feeding H_2S might enhance RWGS performance due to H_2S acting as the hydrogen source to reduce CO_2.

    To improve the catalytic activity of Pt catalysts for methylcyclohexane (MCH) dehydrogenation, which is utilized for hydrogen transportation, the effects of the addition of Se on the performance of Pt/TiO2 catalysts were investigated. In Se/Pt/TiO2 catalysts, even a small amount of Se addition (Se/Pt = 0.01) improved the catalyst stability. Se was highly dispersed on the Pt/TiO2 surface, without volatilizing in a reducing atmosphere at temperatures below 450 °C, and did not form an alloy with Pt. The analysis of adsorption-desorption characteristics revealed that the addition of Se promoted the desorption of products, including the main product, toluene. Moreover, an electron donation effect from Se to Pt was observed by FT-IR measurement after the reduction. The desorption characteristic caused by the electron donation effect suppressed the deterioration of the catalyst and allowed stable catalytic activity toward the MCH dehydrogenation reaction.

    Thermal decomposition treatment (TDT) is a typical recycling method for CFRP. However, the recovered CFs (rCFs) tend to show a decrease in performance owing to the thermo-oxidation during this process. In particular, the thermo-oxidation rates of the outer and inner parts of CFRP are different during TDT; thus, the amount of damage is different between the rCFs collected from the outer (oCFs) and inner (iCFs) parts of CFRP. This study investigated the tensile fracture characteristics of the oCFs and iCFs of the CFRP laminates subjected to TDT, through the single-fiber tensile test and fracture surface observations. The tensile strength of the iCFs was higher and presented a narrower variation than that of the oCFs because the fracture of iCFs occurred from the largest pit formed on the skin whereas that of oCFs occurred from the largest defect in the core. Finally, the strength distribution of the rCFs collected randomly from the TDT treated CFRP was estimated using a mixture distribution model with the aid of the experimental data. The model fitted the strength distribution well. The results indicated that the strength of the rCFs varied more widely with an increase in the number of rCFs undergoing the core fracture.

    <p>The effective utilization of carbon fibers recovered during the thermal decomposition recycling of carbon-fiber-reinforced plastic (CFRP) was investigated. Carbon fibers have a uniform diameter and a suitable size for the use as a combustion catalyst for particulate matter (PM). Thus, in this study, carbon fibers were used as a template to synthesize hollow-form LaNiO<sub>3</sub> perovskite-type oxide via the precursor accumulation method. The calcination temperature was lowered by the internal heat supply from the combustion of the carbon template. Hollow-form LaNiO<sub>3</sub> exhibited the same chemical properties as LaNiO<sub>3</sub> prepared via the common sol–gel method. The morphology of the hollow form decreased the bulk density of the catalyst, resulting in enhanced contact with PM and, consequently, high PM combustion efficiency.</p>

    Selenium and its compounds in high concentration are toxic for humans, especially selenate (VI) is the most toxic due to its high solubility in water. To promote the reductive reaction of Se(VI) to Se(IV) or Se(0), which is relatively easy to remove in water, noble metal particles were added as reaction sites with a reductant. The highest removal performance of selenate in aqueous solution was achieved using rhodium particles supported on TiO_2 (Rh/TiO_2). Selenate was rapidly reduced with hydrazine on the metal particle, leading to a selenium deposition on the particle inhibiting the stable reductive reaction. On the other hand, when a weaker reductant such as formaldehyde was used for the selenate reduction, the selenium deposition was suppressed due to its low reactivity, resulting in a stable reductive reaction of selenate in water.

    A supported ruthenium catalyst (Ru/Cs+/CeO2) for ammonia synthesis is described which incorporates a large amount of a Cs+ promoter in a porous CeO2 support to enhance the electron donation effect of the alkali promoter on the ruthenium catalyst. Optimization of the Ru and Cs+ promoter contents improves the ammonia synthesis rate to more than 4 times that of the benchmark catalyst (Cs+/Ru/MgO) at 350 degrees C and 0.1 MPa, and the ammonia synthesis rate is stable for 100 h. Introduction of the Cs+ promoter into the support before the Ru impregnation increases the particle size of the Ru catalyst. Despite a decrease in the number of active sites, the TOF of the catalyst is more than 50 times that of Ru (2 wt%)/CeO2. CO adsorption measurements suggest an electron donating effect by the Cs+ promoter to ruthenium metal. Reaction order analysis indicates this is due to a mitigation of hydrogen poisoning.

    Effect of annealing on the separation of resin from CFRP cross-ply laminate via electrical treatment
    © 2019 Elsevier Ltd Carbon fiber reinforced plastics (CFRP) are desirable owing to their high specific strength and rigidity. Traditional recycling methods for these products such as thermal decomposition cause considerable damage to the carbon fibers. In search for better recycling methods, we explored the use of electrical treatment for the separation of resin. Herein, we investigated the effects of annealing on the separation of resin from a CFRP cross-ply laminate molded from unidirectional prepreg (carbon fiber/epoxy) using electrical treatment. The annealing of the CFRP cross-ply laminate [0°/90°]2s was performed at temperatures ranging from 60 °C to 450 °C, followed by the electrical treatment. Experimental results demonstrated that the separation of resin, without the carbon fiber damage, could be achieved by annealing at temperatures close to the epoxy decomposition temperature. For the non-annealed CFRP specimens, the separation of resin was achieved with considerable damage to the carbon fibers.

    Rapid removal of resin from a unidirectional carbon fiber reinforced plastic laminate by a high-voltage electrical treatment
    © 2019 Elsevier B.V. Removal of epoxy resin from a unidirectional carbon fiber reinforced plastic (CFRP) laminate was achieved with an electrical treatment. The treatment was carried out using a two-electrode cell with the CFRP laminate as the anode, and the effect of applying a high voltage was investigated to reduce the treatment time. The results showed that a high voltage in the electrical treatment leads to high weight loss of the unidirectional CFRP laminate. In the digital microscope images of the residue obtained from the electrolyte after the treatment, fragments assumed to be resin were observed. The removal mechanism involved an electrochemical reaction; however, no decomposition product related to the resin was detected in the electrolyte after the treatment. The results supposed that the removal mechanism of the electrical treatment involved peeling off the resin by gas generated by water electrolysis.

    炭素繊維強化プラスチック(CFRP)のリサイクル手法として熱分解による炭素繊維(CF)回収が主流である.しかし切断破砕した後に熱分解されるため,回収されるCFは短繊維となり,用途が限定される.それに対して,電気処理法はCFの熱損傷を抑制して樹脂を分離できるため,長繊維のCF回収が期待できる.しかしCFと樹脂の分離現象は,科学的かつ定量的に明らかにされていないため,電気処理の優位点が示されていない.本研究では,「どのようにCFと樹脂は分離されるのか?」の命題に対して,バイポーラ電解槽による分離メカニズムを電気インピーダンスモニタリングを併用して実験的および理論的な観点から体系的に解明する.

    非平衡プラズマ中で二酸化炭素と水を反応させると,一酸化炭素,酸素,水素が生成するが,その生成ガスに何らかのエネルギーを加えると元に戻ってしまう.このため二酸化炭素の有効利用に非平衡プラズマを利用できないでいた.本研究では,プラズマ反応ガスからメタン生成に必要な成分(一酸化炭素と水素)を,触媒上に吸着・貯蔵し,触媒を非定常的に加熱することで,メタンを生成させるという独自手法を提案する.非平衡プラズマと非定常触媒反応を協奏的に利用して,二酸化炭素と水という最終生成物からメタンを生成するという非常に挑戦的な研究である.二酸化炭素の有効利用の新たな突破口を開くという意味でも,研究遂行の意義は大きい.

    工場廃液に含まれる毒性金属イオンの処理工程で課題となっている水中での酸化/還元反応に対して,申請者らは担持貴金属触媒の利用が有効であることを見出した.これにより画期的な処理プロセスの構築が期待されるが,そのためには反応機構の解明と触媒の高性能化が必要で,またプラントの実現可能性も調べる必要があった.本研究ではそれらの課題に対して各種検討を行い,亜ヒ酸酸化の反応機構を解明するとともに,セレン酸還元触媒の飛躍的な長寿命化に成功した.さらに,亜ヒ酸酸化の反応速度が本研究の触媒反応速度でも実用性があり,それを用いたヒ素処理プロセスが現状のプロセスよりもトータルコストが低くなることがわかった.
