Recent advances in CO2 hydrogenation to light olefins
CO2加氢制低碳烯烃过程的开发和应用不仅可以减缓因温室气体大量排放而带来的环境问题,同时也开辟了制备重要化学品的新路线.由于CO2分子高度稳定,实现其高效且定向活化和转化极具挑战.本工作综述了当前CO2加氢制低碳烯烃的研究进展,重点分析了费托合成(CO2-FTO)路线和甲醇中间体(CO2-MTO)路线的优缺点.介绍了影响CO2活化和低碳烯烃生成的关键因素,包括助剂种类、载体结构以及表面缺陷位点浓度等.同时,研究了分子筛孔道结构和酸性对甲醇转化制烯烃的影响机制.
The successful development and application of CO2 hydrogenation to light olefins can not only alleviate the environmental issues caused by the massive emission of greenhouse gases,but also open up a new way for the preparation of important high-value chemicals.Due to the chemical inertness of CO2 molecules,selectively activation and conversion of CO2 into target light olefins remain highly challenging.In this work,we review the current research progress in the hydrogenation of CO2 to light olefins,with a focus on analyzing the advantages and disadvantages of the Fischer-Tropsch synthesis(CO2-FTO)route and the methanol intermediate(CO2-MTO)route.The key factors,such as the type of additives,the structure of the carrier and the concentration of surface defect sites,affecting the activation of CO2 and the formation of light olefins are discussed in detail.Meanwhile,essential role of the pore structure and acidity of zeolites in conversion of methanol intermediates to olefins is analyzed.
