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

进行了CO2还原的设计，并进行了催化剂在较高进料速率条件下的初步实验。以颗粒型和结构型Ni/CeO2和Ru/CeO2为催化剂，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，对反应器的隔热效果进行了实验。实验取得了成功，并通过改变进气比例和总流量对各种条件进行了试验。2023年3月，在东京农业技术大学举行的第88届日本化学工程师学会年会上，也公布了所获得的结果。手稿正在准备中，很快就会提交。

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.
