Optimal activated carbon for separation of CO2 from (H2 + CO2) gas mixture

Abstract Seven types of activated carbon were used to investigate the effect of their structure on separation of CO2 from (H2 + CO2) gas mixture by the adsorption method at ambient temperature and higher pressures. The results showed that the limiting factors for separation of CO2 from 53.6 mol% H2 ...
