[2D20] Effect of hydrogen or hydrocarbon addition on carbon dioxide conversion reaction over metal-containing zeolite

○Shuhei Yasuda¹, Takeshi Matsumoto¹, Toshiyuki Yokoi¹ (1. Institute of Innovative Research, Tokyo Institute of Technology)

大気中のCO₂を削減し持続可能なプロセスを開発することは、社会が直面している最も緊急かつ困難な課題の一つである。CO₂を化学的に付加価値の高い化合物へ直接変換する触媒プロセスの開発が盛んに検討されている。本研究では、二酸化炭素を基質に水素もしくは炭化水素を用いて付加価値化合物の合成を可能にする触媒の開発を目的に、金属の種類、金属種の状態が二酸化炭素転換活性に与える影響について検討した。

[2D21] A newfound zeolite catalyst for highly efficient carbonylation

○Jie YAO¹, Guohui Yang¹, Noritatsu Tsubaki¹ (1. University of Toyama)

Up to now, the member of zeolite family has expanded to more than 230. However, only little part of them have been reported as catalysts. Discovering potential zeolites for new reactions is significantly important, especially in industrial applications. We found a new zeolite catalyst Al-RUB-41 with specific morphology and channel orientation. The mass-transfer distance along 8-MR of this zeolite is very short. This specific nature endows Al-RUB-41 with efficient catalytic ability to dimethyl ether carbonylation beyond 95% methyl acetate selectivity. By erasing the acid sites on outer surface, Al-RUB-41@SiO₂ catalyst achieves a long-time and high-efficiency activity without any deactivation trend.

4:45 PM - 5:00 PM

[2D22] Selective Conversion of CO₂ into para-xylene over a ZnCr₂O₄-ZSM-5 Catalyst

○Weizhe Gao¹, Guohui Yang¹, Noritatsu Tsubaki¹ (1. University of Toyama)

An oxide-zeolite (ZnCr₂O₄-ZSM-5) catalyst for directly converting CO₂ to aromatics was designed and developed. It showed high PX/X (the C-mol ratio of p-xylene to all xylene) and PX/aromatics (the C-mol ratio of p-xylene to aromatics) ratios, which reached 97.3 and 63.9%, respectively.

5:00 PM - 5:15 PM

[2D23] Plasmon-induced reverse water gas shift reaction using reduced molybdenum oxide catalyst

○Kazuki Kusu¹, Yasutaka Kuwahara^1,2,3, Hiromi Yamashita^1,2 (1. Division of Materials and Manufacturing Science, Graduate School of Engineering, Osaka University, 2. Unit of Elements Strategy Initiative for Catalysts & Batteries (ESICB), 3. JST PRESTO)

水素還元処理により欠陥が多数導入された還元型モリブデン酸化物は、可視光域から近赤外光域にかけてプラズモン由来の光吸収を示す。本研究では、Pt担持還元型モリブデン酸化物を用いて、低温(~200 ℃)、常圧水素下で逆水性ガスシフト反応を行った。暗所下ではCOが主生成物として生成し、可視光照射下では、さらに触媒活性が向上することを見出した。各種キャラクタゼーションにより、反応機構や光吸収が及ぼす影響について検討した。
