Adsorption-selective carbon membrane for gas separation

摘要

The preparation and characterisation of adsorption-selective microporous carbon carbon membranes is described. The prepared membranes can separate the components of a gas mixture depending on their adsorption properties instead of the nolecular size. Thus, these membranes are suitable to separate non-adsorbable or weakly adsorbable components (i.e. N_2, H_2, O_2, etc.) from the more strongly adsorbable components (i.e. hydrocarbons) in a gas mixture.
