Resumo: | Abstract Equilibrium adsorption isotherms were obtained experimentally by a static method for a binary component hydrogen-methane mixture on activated carbon and 5A molecular sieve adsorbents. The temperature range 303-333 K and pressure range 0 - 4 MPa were examined. Methods for predicting gas-mixture equilibrium adsorption data from the pure-component isotherms were evaluated. Extended Langmuir model correlated the adsorption of binary mixtures fairly well. In all cases mutual interference was found, that is, the amount of a given gas adsorbed at a given partial pressure was always less in the mixture than it would have been if the other gaseous component had not been present. It was found that the amount adsorbed of gases per unit bulk volume for 5A molecular sieve was higher than for activated carbon. Furthermore, 5A molecular sieve showed better adsorption characteristics than activated carbon in mass transfer properties, affinity, selectivity and heat of adsorption. |

Abstract Equilibrium adsorption isotherms were obtained experimentally by a static method for a binary component hydrogen-methane mixture on activated carbon and 5A molecular sieve adsorbents. The temperature range 303-333 K and pressure range 0 - 4 MPa were examined. Methods for predicting gas-mixture equilibrium adsorption data from the pure-component isotherms were evaluated. Extended Langmuir model correlated the adsorption of binary mixtures fairly well. In all cases mutual interference was found, that is, the amount of a given gas adsorbed at a given partial pressure was always less in the mixture than it would have been if the other gaseous component had not been present. It was found that the amount adsorbed of gases per unit bulk volume for 5A molecular sieve was higher than for activated carbon. Furthermore, 5A molecular sieve showed better adsorption characteristics than activated carbon in mass transfer properties, affinity, selectivity and heat of adsorption. |
