催化氢化二氧化碳研究进展

Research Progress of Catalytic Hydrogenation of Carbon Dioxide

催化氢化是二氧化碳资源化利用的重要技术手段,该类反应可生成甲烷、甲酸或甲醇等有机物,因而具有广阔的应用前景。对国内外催化氢化CO2技术的研究现状进行了综述,介绍了其研究方向:通过改变催化剂结构、种类等因素,开发在中低温、中低压下具有高活性、高选择性的催化剂,提高催化氢化二氧化碳的转化率;基于此进行催化氢化二氧化碳反应机理及理论的深入研究。

The catalytic hydrogenation is an important technology for the resource utilization of carbon dioxide and is considered to have a broad application prospect because some organic compounds,including methane,formic acid or methanol,can be produced.The present research of the catalytic hydrogenation of carbon dioxide at home and abroad was reviewed.The major works concerned include developing more activated and alternative catalysts under low-medium temperature and pressure through changing the structure and species of the catalysts for improving the conversion rate of CO2;the reaction mechanisms and theories of catalytic hydrogenation of carbon dioxide.
