Chapter Two - Kinetics of Catalytic Dehydrogenation of Propane over Pt-Based Catalysts

Abstract

Abstract Dehydrogenation of propane (DHP) is becoming an important process for increasing propylene productivity. In this review, the DHP over Pt-based catalysts is surveyed from the kinetic point of view. After a short introduction of propane dehydrogenation process in Section 1 , the DFT calculation results of the main and side reactions of the DHP over different Pt crystal planes as well as on Pt-Sn alloys are summarized in Section 2 to provide a fundamental understanding of the reaction mechanism of the DHP. In Section 3 , the macrokinetics of the DHP, coking, deactivation, and coke burning-off are summarized and then reexamined from the view of microkinetic analysis based on the DFT calculation results. Finally, the intensification of the DHP by steam dehydrogenation and selective oxidation of hydrogen are briefly reviewed.
