摘要
CO_(2)加氢制低碳烯烃不仅可以节约化石燃料,还可以将化工产业的废产物CO_(2)加以转化利用,既可以减少CO_(2)造成的环境问题,又可以制备人们生活中必需的化学品。合理开发利用CO_(2)能够代替化石燃料,对人类生产生活和经济发展具有重要意义。该文详细叙述了CO_(2)加氢合成低碳烯烃的反应机理。针对CO_(2)加氢制备低碳烯烃的两条路径CO_(2)-Fischer-Tropsch直接法(CO_(2)-FT)和甲醇介导间接法(CO_(2)-MTO),分别阐述了两种路径所用催化剂类型、助剂、载体对CO_(2)转化率和烯烃选择性的影响,最后对CO_(2)加氢制低碳烯烃催化剂的研究方向进行了展望。
CO_(2)hydrogenation to low-carbon olefins can reduce fossil fuel consumption,also convert and utilize CO_(2),the waste product from chemical industry,to reduce environmental problems while synthesize essential chemical products needed in people's lives.Rational development and utilization of CO_(2)can replace usage of fossil fuels,which is of great significance to social and economic development.In this review,the reaction mechanism of CO_(2)hydrogenation to light olefins was described in detail.In view of the two routes for CO_(2)-Fischer-Tropsch direct method(CO_(2)-FT)and methanol-mediated indirect hydrogenation of CO_(2)(CO_(2)-MTO)to low-carbon olefins,the effects of catalyst types,promoters and substrates used in the two routes on CO_(2)conversion and olefin selectivity were discussed,respectively.Finally,the research direction of catalysts for CO_(2)hydrogenation to low-carbon olefins was prospected.
