Characterization of carbon molecular sieve

Carbon molecular sieve is the critical material of the enrichment CBM variable pressure absorption units,whose properties directly determine the function of the variable pressure absorption units.The specific surface area and pore size distribution of carbon molecular sieve is investigated according to analyzing N2 adsorption and desorption isotherms at 77 K.Compare the adsorption ability of carbon molecular sieve for N2,O2,CH4,H2 according to adsorption experiments.Adsorption rates of N2 and CH4 are analyzed,which make it easy for determining the separation ability of different carbon molecular sieve for gas.
