Review in Catalysts Comprising F-T Components for Mixed Alcohols Synthesis from Syngas

低碳混合醇由于其具有巨大的工业应用价值,而成为C1化工中重要的研究内容。CO加氢合成低碳醇的过程为强放热、体积缩小的可逆反应,并且需要C-O键断裂的表面解离吸附,来实现碳链的增长,以及C-O键保留的表面非解离吸附来实现CO的插入成醇。包含F-T组元的混合醇催化剂分别采用Co、Fe组分及甲醇合成活性组元,来实现二者的协同作用。本文对含Co、含Fe催化剂活性中心的作用方式、关键影响因素进行简要阐述,并指出低碳混合醇催化剂与合成新工艺的整合开发,是提高醇选择性和产率,实现工业化应用的关键。

Mixed alcohols synthesis is an important process in the field of C1 chemistry because of its huge in-dustrial application value. The process is a strong exothermic, volume reduced reaction,which needs the C-O bond cleavage and Surface dissociative adsorption to realize the growth of carbon-chain,and non-dissociative CO adsorption for CO insertion and alcohol formation. Using F-T synthesis active components and methanol synthesis active components to achieve the synergy in mixed alcohol catalyst comprising Co、Fe.This article briefly described the action mode of the active centers and the key factors in catalyst containing Co, Fe Cata-lyst. Integrating the development of low-carbon mixed alcohol catalyst and the new process of synthesis is the key to improve the selectivity and yield of alcohol , and is the point to realize the industrial application.
