Three bituminous coals were extracted with 12 different solvents and one solvent mixture in the presence of ultrasonic energy at ambient temperature. The effects of the extraction on the microporosity of the coals was determined by measuring the adsorption of CO, at 298 and 195 K and of N, at 77 K.

The kinetically selective adsorption of CO2 in CH, was studied using three commercially available molecular sieve carbons. All as-received carbons examined in this study exhibited poor kinetic selectivity. However, heat-treatment at around 1273 K significantly improved the kinetic selectivity of one
