摘要
随着人们生活水平提高和工业日益快速增长的需求,对天然气的需求越来越大,在较长时间内出现供不应求的局面。煤制天然气是煤经气化、合成气变换、净化以及甲烷化形成的过程,其中高温甲烷化催化剂的研究与开发备受关注。本文首先对高温甲烷化催化剂国内外发展概况进行了综述,并对高温催化剂的组成及其失活原因进行了分析,失活原因主要包括:硫中毒、烧结和析碳,最后提出高温甲烷化催化剂的研究方向,旨在为高温甲烷化催化剂的研发提供借鉴与参考。
With the improvement of people＇s living standards and rapid industrial growth,the demand for natural gas has become increasingly greater and the supply can not meet the demand for natural gas for a long time.Coal-based synthetic natural gas production consists of coal gasification,shift reaction,purification and methanation of synthetic gas.More attention is paid on high temperature methanation catalyst development.In this paper,firstly,the status and progress of high temperature methanation catalyst development in China and overseas are introduced,and the composition and deactivation of catalyst are discussed.Deactivation is mainly caused by sulfur poisoning,sintering and carbon deposition.The research direction of high temperature methanation catalyst is presented.
