1.0×105 Pa. The adsorption ability of Co-IM-mIM membrane will change under different pressure conditions because at high pressures, high concentration of a gas such as CO2 may swell the polymer... of adsorption ability of Co-IM-mIM membrane towards single gas in the trans-membrane pressure range [47]. Moreover, the ideal selectivities of H2/N2, H2/CO2, and H2/CH4 still maintain high values, which......
of ethanol and acetone concentrations. PAn/SnO2 materials have high selectivity, fast response-recovery time and low operation temperature to VOCs, but pure PAn and SnO2 do not have. Key words: gas...
