Design of powerful structured catalysts contributing to convert GHG by CO2 methanation

进行了CO2还原的设计，并进行了初步实验以在相对较高的进料速率条件下测试催化剂。采用颗粒型和结构型Ni/CeO 2和Ru/CeO 2催化剂材料对CO2甲烷化反应进行了研究。此外，为了在不向反应器提供外部热量的情况下维持甲烷化反应，实验了使反应器绝热的效果。实验是成功的，通过改变进料气体的比例和它们的总流量来测试各种条件。所获得的结果也于2023年3月在东京农工大学举行的日本化学工程师学会第88届年会上发表。手稿正在编写中，不久将提交。

The design of CO2 reduction was performed and preliminary experiments were carried out to test catalysts at relatively higher feed rate conditions. The CO2 methanation reaction was investigated by using granular and structured type Ni/CeO2 and Ru/CeO2 catalyst materials. Furthermore, the effect of insulating the reactor was experimented in order to sustain the methanation reaction without providing external heat to the reactor. The experiment was successful and various conditions were tested by varying the ratios of feed gases and their total flow rate. The obtained results were also presented during the 88th Annual Meeting of the Society of Chemical Engineers Japan at Tokyo University of Agriculture and Technology, Tokyo in March 2023. The manuscript is under preparation and will be submitted soon.
