Research progress on oxidative cracking catalysts of light alkanes to light olefins
摘要
Abstract
Oxidative cracking process of light alkanes(C2～C6 alkanes)is one of the key pathways for producing light olefins.Oxidative cracking can be divided into two types:Catalytic oxidative cracking(COC)and redox oxidative cracking(ROC).In COC systems,the presence of oxygen often leads to over-oxidation,resulting in higher CH4 and COx yields and lower olefin yields.Although ROC systems decreases the issue of over-oxidation,their high operating temperatures and process complexity limit broader industrial application.The reaction mechanism of COC process was summarized,and catalysts used in this system were summarized,including rare-earth metals,noble metals,alkali metals and other catalysts.Meanwhile,the ROC reaction mechanism was discussed,along with the vanadium-based and perovskite catalysts.Based on analysis of current research,the challenges faced by oxidative cracking catalysts were summarized,and the future development direction was proposed,aiming to provide reference for the development of new and highly efficient oxidative cracking catalysts.关键词
