摘要
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 typical catalytic reaction pathways for heterogeneous phase conversion of CO2 to useful valueadded chemicals are reviewed,including oxidative hydrogenation of CO2 to make methanol,methanation of CO2,and using CO2 as weak oxidizer to oxidize low carbon alkane to dehydrogenate and make olefins.The key technologies and difficult problems in the heterogeneous phase conversion process,such as characteristics of the catalysts involved,reaction mechanisms and challenges in industrial use are analyzed emphatically. The development prospects for the resource application of heterogeneous phase conversion is imaged and proposed.
