摘要：甲醇同系化是一项很有前景的乙醇制备工艺,一般采用Ⅷ族金属可溶性盐作为催化剂,含碘化合物作为助催化剂。本文根据活性金属元素种类不同对甲醇同系化制乙醇催化体系进行分类,以此为基础对工艺条件优化、反应机理的研究现状进行了总结,指出现有催化剂体系乙醇产率偏低仍然是制约该工艺商业化的最大障碍。最后对甲醇同系化催化剂研究进行了展望,提出非均相多金属复合型催化剂的研制、非卤素类助剂的添加、低压稳定性甲醇同系化催化剂的开发是甲醇同系化研究的主要方向。
The methanol homologation is one of the promising technologies for ethanol production.Soluble salts of group-Ⅷ metals are generally used as catalysts,and iodine compounds as promoters.In this paper,catalysts are categorized according to the variety of active metal elements,and the mechanism of methanol homologation reaction is analyzed based on the former category.The reported work indicated that the low ethanol yield was the major restriction for the commercialization of this technology.Finally,the outlook for the future development of methanol homologation catalyst and further investigation of mechanism is provided in light of the current research status,regarding composite catalyst with multimetallic,catalyst modified with no halogen element,as well as low pressure-resistant catalysts.
