综述了CO_2非均相转化为多种化学品的若干途径,主要包括CO_2加氢制甲醇和CO_2甲烷化工艺及作为弱氧化剂氧化低碳烷烃脱氢制烯烃工艺,着重分析了非均相转化过程的关键技术和难点问题,包括催化剂的特性、催化反应机理及工业应用中存在的问题,同时对非均相资源化应用的发展前景提出设想。
Several ways of heterogeneous conversion of CO_2 to many chemicals are summarized, including the processes of CO_2 hydrogenation to methanol and CO_2 methanation and the oxidation of lower alkanes to olefins as weak oxidants. The heterogeneous conversion process Including the characteristics of the catalyst, the mechanism of the catalytic reaction and the problems in the industrial application, as well as the development prospects of the application of the heterogeneous resource.
