摘要/Abstract

摘要： CO2直接生产烃类、醇类和酯类等化学品是CO2减排及利用的有效措施。由于CO2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CO2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利益和环保效益；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CO2直接转化为烯烃和芳烃，才能实现CO2加氢制低碳烯烃、轻质芳烃等烃类物质的真正突破。CO2直接生产酯类化合物原子利用率最高，反应条件温和，是典型的绿色化工过程，具有良好的工业应用前景。

Abstract: The direct production of hydrocarbons, alcohols, and esters from CO2 is an effective measure for CO2 reduction and utilization. Due to the generation of water in the process of direct production of hydrocarbons and alcohol compounds from CO2, the atomic utilization rate is low, and hydrogen gas is not effectively utilized. The direct production of methanol and polyols from CO2 under the action of a catalyst has economic and environmental benefits only when obtaining cheap "green hydrogen"; using new energy sources such as solar energy and wind energy to produce "green hydrogen" and effectively reducing the production cost of "green hydrogen" through technological progress, CO2 can be directly converted into olefins and aromatics under the action of efficient catalysts, achieving a real breakthrough in CO2 hydrogenation to produce low-carbon olefins, light aromatics and other hydrocarbon substances. The direct production of esters from CO2 has the highest atomic utilization rate and mild reaction conditions, which is a typical green chemical process and has a broad industrial application prospect.
