摘　　要：CO_(2)直接生产烃类、醇类和酯类等化学品是CO_(2)减排及利用的有效措施。由于CO_(2)直接生产烃类、醇类化合物的过程中生成水,原子利用率低,氢气未被有效利用。通过CO_(2)在催化剂作用下直接生产甲醇和多元醇类化合物,在获取廉价“绿氢”的情况下才具有经济效益和环保效益;利用太阳能、风能等新能源来生产“绿氢”,并通过技术进步有效降低“绿氢”生产成本,在高效催化剂作用下将CO_(2)直接转化为烯烃和芳烃,才能实现CO_(2)加氢制低碳烯烃、轻质芳烃等烃类物质的真正突破。CO_(2)直接生产酯类化合物原子利用率最高,反应条件缓和,是典型的绿色化工过程,具有良好的工业应用前景。The direct production of hydrocarbons,alcohols,and esters from CO_(2)is an effective measure for CO_(2)reduction and utilization.Due to the direct production of hydrocarbons and alcohol compounds from CO_(2),water is generated,resulting in low atomic utilization and a waste of valuable hydrogen gas.The direct production of methanol and polyol compounds through CO_(2)under the action of a catalyst has economic and environmental benefits only when obtaining cheap green hydrogen;By utilizing new energy sources such as solar energy and wind energy to produce green hydrogen and effectively reducing the production cost through technological progress,CO_(2)can be directly converted into olefins and aromatics under efficient catalysts,achieving a true breakthrough in CO_(2)hydrogenation to produce low-carbon olefins,light aromatics and other hydrocarbon substances.The direct production of esters from CO_(2)has the highest atom utilization rate and mild reaction conditions,which is a typical green chemical process.After further improving the catalyst performance and optimizing the process,it has the most industrial application prospect.
