摘要
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.
