摘要:

合成气直接催化转化制乙烯、丙烯等低碳烯烃因具有原料来源广泛、流程较短等优点,成为目前合成气催化转化和烯烃制备技术的一个重要发展方向。本文首先介绍了合成气经费托合成直接制备低碳烯烃的路线(FTO),简单概括了铁基和钴基催化剂的研究进展以及催化反应机理。随后重点综述了近年来提出并发展的基于双功能催化体系的合成气直接制低碳烯烃路线(STO),详细阐述了金属氧化物的组成、配比等以及分子筛的酸性、孔道等性质对反应性能的影响,同时讨论了双功能催化体系以乙烯酮或甲醇/二甲醚为关键中间体的催化反应机理。最后对双功能催化体系的研究方向和挑战进行了展望。

Abstract:

The direct conversion of syngas to light olefins such as ethene and propene has become a significant and attractive process in syngas conversion and olefin synthesis due to the abundant resources and its relatively short process. In this review, the direct synthesis of light olefins from syngas via Fischer-Tropsch (FTO) route is introduced at first with the emphasis on the research progress of iron-based and cobalt-based catalysts and the catalytic reaction mechanism. Then the direct conversion based on the recently proposed and developed bifunctional catalytic system consisting of oxides and zeolites (STO) is addressed in detail. The effects of oxide composition and ratio, zeolite acidity and pore structure on the STO catalytic performance are elaborated. The catalytic mechanism for reactions with ketene or methanol/dimethyl ether as key intermediate is also discussed. The directions and challenges on the development of the bifunctional catalysis system are finally proposed.

Key words: syngas, light olefins, catalysis, bifunctional catalyst, Fischer-Tropsch synthesis, reaction mechanism
