Abstract

This review provides an analysis of prior research on the kinetics of the trimerization of ethylene to 1-hexene over existing chromium-based catalytic systems. It discusses the known mechanisms and reaction steps for the formation of 1-hexene as well as olefin by-products. The effects of catalytic system composition, temperature, pressure, reaction time, and the presence of hydrogen on the kinetics of 1-hexene formation are also touched upon. The kinetic models of ethylene trimerization to 1-hexene known from published literature are presented.

铬基催化剂将乙烯选择性三聚化为 1-己烯的动力学

摘要本综述分析了之前关于在现有铬基催化体系下乙烯三聚为 1-己烯的动力学研究。它讨论了生成 1-己烯和烯烃副产物的已知机理和反应步骤。此外，还讨论了催化系统组成、温度、压力、反应时间和氢的存在对 1-己烯形成动力学的影响。介绍了已发表文献中已知的乙烯三聚成 1-己烯的动力学模型。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
