| Abstract: | Carbon molecular sieve with high methane/nitrogen separation performance is the premise for low concentration coalbed methane separation by swing pressure adsorption.Coconut shell carbonized materials was used as raw material in this paper.The raw material was activated to prepare carbon precursor,and then deposited by CH4 to prepare carbon molecular sieve(CMS).The effects of deposition time,deposition temperature,CH4 concentration and velocity in CH4/N2 mixture on the separation performance of CMS in metha... |
