NICKEL CATALYSTS SUPPORTED ON AMINOFUNCTIONALIZED MCM-41 FOR SYNGAS METHANATION

摘要

Increasing demand and price volatility of natural gas have madernthe production of synthetic natural gas (SNG) from carbon sourcesrnattractive in certain regions of the world. Energy developments ofrn‘‘coal to natural gas’’, which rely on the rich coal resources of China,rnnot only meet the development direction of clean coal utilization butrnalso guarantee the effective supplement of natural gas. Ni-basedrncatalysts have attracted wide attention in syngas methanation becausernof their considerable activity, good selectivity, and moderate price.rnHowever, the conventional Ni-based catalyst is easily sintered at highrntemperature for methanation, inducing obvious catalyst activityrndecrease[1]. Therefore, developing Ni-based catalyst with stablerncatalytic performance at high temperature is of great interest.
