摘要

本文综述了近二十年来沸石丙烷脱氢催化剂的研究进展。讨论了工业上重要的丙烷脱氢制丙烯反应的主要特点,包括其能力、局限性、机理以及实际实现的进料转化率和丙烯选择性等催化性能参数。特别强调的是催化参数在时间上的稳定性,在流和反应再生循环。概述了现有的合成分子筛上金属基和氧化物基催化剂的策略。为了确保更好地理解当前的研究趋势,近年来发展的先进方法将在单独的部分进行讨论。对于每一类催化剂,将其催化性能与该工艺中常用的氧化物基催化剂进行比较。重点研究了活性位点的“结构-催化性能”和“合成条件-结构”关系。最后,对可能用于开发新一代工业催化剂的最有希望的策略作出了结论。

Recent Advances in the Development of Zeolite Catalysts for Propane Dehydrogenation: I. Zeolite-Supported Platinum Catalysts (A Review)

This review provides an analysis of the advances in the development of zeolite catalysts for propane dehydrogenation reported over the past two decades. It discusses the main distinctive features of the industrially important reaction of propane dehydrogenation to propylene, including its capabilities, limitations, mechanism, and the actually achieved catalytic performance parameters such as feed conversion degree and propylene selectivity. Particular emphasis is placed on the stability of the catalytic parameters in time on stream and in reaction-regeneration cycles. An overview of the existing strategies for the synthesis of metal-based and oxide-based catalysts supported on molecular sieves is provided. To ensure a better understanding of the current research trends, the advanced approaches developed in recent years are discussed in a separate section. For each catalyst class, their catalytic performance is compared with that of the oxide-based catalysts commonly applied for this process. Particular attention is paid to research on “structure–catalytic performance” and “synthesis conditions–structure” correlations for active sites. Finally, conclusions are made regarding the most promising strategies that may be of use for the development of a new generation of industrial catalysts.

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.
