摘要:

低碳烯烃是重要的化工原料,直接法合成气制低碳烯烃是非石油路线生产烯烃的新途径。本文首先介绍了直接法合成气催化转化制烯烃的两种工艺路线,即双功能催化剂反应偶联和费-托合成路线制低碳烯烃;接着对CO加氢反应的热力学进行了分析。重点从催化剂活性相、尺寸效应、助剂、金属载体相互作用等方面对合成气直接法制低碳烯烃催化剂的研究进展以及CO加氢反应机理进行了综述。文章指出:在基础研究方面,反应机理仍待进一步明晰,催化剂的开发应聚焦于对O/P及产物链长的精准调控;工业化方面,要考虑到真实的工业化反应环境与实验室反应之间的差异,同时要注意与上下游的产业联合。

Abstract:

Lower olefins are important chemical raw materials and the direct synthesis of lower olefins from syngas is a new non-petroleum route. This article first introduces two routes of synthesis gas catalytic conversion to olefins: the coupling route and the Fischer-Tropsch route. Then the thermodynamics of the CO hydrogenation reaction was analyzed. The research progress of the catalysts for direct synthesis of low-carbon olefins from syngas and the reaction mechanism of CO hydrogenation are reviewed mainly from the aspects of active phase, size effect, promoters, and metal support interactions. As an outlook, we believe that the reaction mechanism still needs to be further clarified through basic researches, and the catalyst development should focus on the precise control of O/P and product’s chain length. In terms of the industrialization, it is necessary to take into account the difference between the real reaction environment in plant and laboratory reactions, and to pay attention to the compatibility with both upstream and downstream.

Key words: syngas, lower olefins, catalyst, reaction mechanism, industrial application
