摘要:

将CO/CO2直接转化为芳烃是一种极具挑战性的非石油路线合成途径。本文主要对CO/CO2通过不同反应途径制取芳烃过程中复合催化剂的开发和反应机理的研究进展进行了综述。阐述了利用反应耦合思想,构筑的复合催化剂在CO/CO2的高效转化和产物调控等方面取得了突破性的进展。重点介绍了复合催化剂用于CO加氢制芳烃主要的两种反应途径,活性金属的类别、分子筛的结构与酸性和活性组分的组装方式与接触度对CO2加氢制芳烃催化性能的影响。指出协同加氢与芳构化反应活性的匹配是影响催化剂性能的关键。提出开发高效稳定的催化剂用于提高CO/CO2的转化率和芳烃产物的产率以及反应机理的探索仍然是未来研究的重点。

Abstract:

The direct conversion of CO/CO2 to aromatics is a very challenging non-petroleum pathway, which has important strategic significance. In this paper, the research progress of composite catalysts development and the reaction mechanism in producing aromatics by different reaction routes of CO/CO2 were reviewed. Based on the reaction coupling theory, breakthroughs of the composite catalyst in CO/CO2 conversion and product regulation have been made. Two main reaction pathways of CO hydrogenation to aromatics using composite catalysts, as well as the influences of active metals types, the structure and acidity of zeolites and the assembly mode and the contact degree of active components on the catalytic performance were emphatically introduced. The reactivity matching between the synergetic hydrogenation and the aromatization is the key factor affecting the performance of catalysts. The development of efficient and stable catalysts to improve the conversion rate of CO/CO2 and the yield of aromatic products, and the exploration of the reaction mechanism remain the focus of future research.

Key words: carbon monoxide, carbon dioxide, hydrogenation, aromatics, composite catalyst, reaction mechanism
