Research advance in chromium-based catalysts for propane direct dehydrogenation to propylene
摘要
Abstract
As a crucial basic chemical raw material,propylene holds significant strategic importance in chemical industry.With the rapid expansion of propylene downstream industrial chains and the feedstock advantages brought by shale gas revolution,propane direct dehydrogenation(PDH)process has emerged as one of the mainstream technical routes for propylene production due to its substantially reduced manufacturing costs.In this context,developing high-efficiency chromium-based catalysts with integrated high catalytic activity,product selectivity and stability has become a key research focus in this field.According to the research status of PDH chromium-based catalysts,the PDH reaction mechanism and the catalyst deactivation mechanism under chromium-based catalysts were reviewed.The influences of important components of PDH chromium-based catalysts,such as active centers,supports and promoters on their catalytic performance were analyzed.And various preparation methods and improvement strategies for PDH chromium-based catalysts were summarized.Finally,the future development directions of PDH chromium-based catalysts were prospected.关键词
