Synthesis of ordered mesoporous carbon molecular sieve and its adsorption capacity for H2, N2, O2, CH4 and CO2

Ordered mesoporous carbon is a recently developed material. To test its potential application for adsorption, such a material was synthesized using silica SBA-15 as the template and sucrose as the carbon source. The ordered structure and the mesopore dimension of the material were proven with XRD, SEM and TEM examinations. Adsorption data of H2, N2, O2, CH4 and CO2 on the ordered mesoporous carbon were collected with a typical volumetric method for a pressure range up to 11 MPa. Potential application for the separation of CO2-CH4-air mixture was indicated.
