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.
