Research progress of propane dehydrogenation to propylene catalysts
摘要
Abstract
Propane dehydrogenation to propylene is one of the important sources of propylene supply.The factors affecting the performance and catalytic mechanism of two kinds of catalysts for propane dehydrogenation to propylene were reviewed.The problems of carrier screening,auxiliary optimization,interaction between carrier and active component and deactivation of various catalysts in recent years were summarized and analyzed.In the process of oxidative dehydrogenation of propane,the V-based catalyst is environmentally friendly,but the deactivation is fast and the activation temperature is high.The activity problem of Mo/W-based catalyst should be solved and the catalytic mechanism should be clarified.The reaction condition of Co-based catalyst is mild,but the process condition suitable for industrial production should be explored.The C-based catalyst should further verify the high temperature tolerance of carbon support and further increase the number and dispersion of functional groups on carbon support.In the process of direct dehydrogenation of propane,the Cr-based catalyst should reduce Cr content while maintaining activity and seek alternative active components.The Pt-based catalyst should increase the dispersion of Pt particles and minimize coking amount.When increasing the activity of Ga-based catalyst,the stable existence time of active specie should be prolonged as much as possible.关键词
