摘要:

选择性加氢在功能材料合成和化学产品提纯等化工领域中有非常重要的应用,并且近年来为减少温室效应的影响,将CO2催化选择性加氢转化成其他有应用价值的物质成为研究热点之一。其中热催化是应用较为广泛、易得到多种目标产物并且获得产品收率较高的方法。目前,利用CO2多相热催化加氢制得甲烷、甲醇、轻烯烃等多种高价值的燃料和化学品已取得了一定进展,但仍存在一些难点问题,其中制备高效催化剂是催化加氢反应的关键问题之一。一直以来,研究人员致力于解决催化剂的活性和选择性问题,通过助剂掺杂和加入功能性载体对催化剂进行改性。针对这些问题,本文简要介绍了CO2催化加氢的研究背景,总结了近5年来热催化CO2加氢制得甲烷、甲醇、轻烯烃产品过程中使用催化剂的种类及对加氢反应的影响,期望为CO2多相催化加氢中新型催化剂的开发提供参考。

Abstract:

Selective hydrogenation has very important applications in the chemical industry such as synthesis of functional materials and purification of chemical products. In recent years, in order to reduce the impact of the greenhouse effect, the selective hydrogenation of CO2 into other valuable chemicals has become a research hotspot. Among them, the thermal catalysis is widely used, easy to obtain a variety of target products and high yield of products. At present, the heterogeneous thermal catalytic hydrogenation of CO2 to produce methane, methanol, light olefins and other high-value fuels and chemicals has made some progresses, but their development is still challenging. The preparation of high-efficiency catalysts is one of the keys. For a long time, researchers have been committed to solving the problem of catalyst activity and selectivity, and modifying the catalysts by doping with additives and adding functional carriers. In response to these problems, this article briefly introduces the background of the catalytic hydrogenation of CO2 and reviews the catalysts used in the heterogeneous thermal catalytic hydrogenation of CO2 into methane, methanol and light olefin products in recent five years. It is expected to provide a reference for the development of new catalysts in the heterogeneous catalytic hydrogenation of CO2.

Key words: Catalytic hydrogenation of carbon dioxide, Thermal catalysis, Methane, Methanol, Light olefins
