甲烷氧化偶联床层控温与撤热的研究进展
Advances in bed temperature control and heat removal during oxidative coupling of methane
摘要
Abstract
The oxidative coupling of methane(OCM)faces a significant challenge to industrial application due to its high reaction temperature and intensive exothermic nature.This review discusses strategies for controlling and removing heat in the OCM process.From the perspective of heat control,this review proposes that adjusting oxygen dilution concentration can partially alleviate hotspots in the catalyst bed caused by deep oxidation.Moreover,using alternative oxidizing gases or catalyst lattice oxygen to replace oxygen in the OCM reaction can effectively regulate heat release while improving ethane/ethylene selectivity.Regarding heat removal,bed hotspots can be effectively reduced by preparing monolithic catalysts using carriers with high thermal conductivity.Additionally,coupling OCM with endothermic reactions like methane reforming can not only reduce temperature rise through heat exchange but also enable integrated treatment of OCM tail gases.关键词
