合成气直接或间接制乙醇非铑基催化剂研究进展

Research advances in syngas direct or indirect conversion to ethanol over non-rhodium supported catalyst

乙醇作为一种清洁绿色能源,具有环境友好的特点,在能源领域显现了广阔的应用前景,研制高活性和选择性并适合工业化的合成乙醇催化剂具有重要的战略意义,非铑基催化剂具有相对较高的催化活性和选择性,并具有工业化的前景,近年来得到广泛的研究。本文介绍了国内外由合成气直接或者间接制乙醇的非铑基催化剂最新研究进展,分析了催化剂的活性组分、载体、助剂以及制备方法对催化活性和选择性的影响,指出了存在的问题,提出了高活性和选择性并且适合工业化的非铑基催化剂的研制是未来的发展趋势。

Ethanol as a clean and green energy has a characteristics of environmental friendly.It shows broad application prospects in the energy field.It is strategic significance to develop the ethanol synthesis catalysts with highly catalytic activity,product selectivity and commercial attraction.Non-rhodium supported catalysts have been studied extensively in recent years as these catalysts produced ethonal with relatively high catalytic activity,product selectivity and commercial attraction.In this paper,the latest overseas and domestic research advances in syngas direct or indirect conversion to ethonal over non-rhodium supported catalyst were introduced.The effects of active components,carrier,promoter and preparation methods on the catalytic activity and product selectivity were analysed.The existing problems were pointed out.It proposed that the development of non-rhodium supported catalyst with highly catalytic activity,product selectivity and commercial attraction was the future development trend.
