Pore size control of a series of activated carbon fibers was attempted by chemical vapor deposition (CVD) of benzene to clarify the influence of the pore distribution on the development of molecular sieving ability. Weight increase by CVD was found to saturate at a certain level respective to the fiber, reflecting their surface areas. However, when saturation was obtained, the molecular sieving...
Catalytic oxidation of NO (380 ppmv) to NO 2 over activated carbon fibres of moderate surface area (∼800 m 2 g -1 ) at room temperature was carried out, to develop oxidative removal of NO from flue gas. The heat treatment of pitch-based activated carbon fibres of moderate surface area markedly increased the conversion of NO to 87% in dry air, 62% in air of 80% relative...
The kinetically selective adsorption of CO 2 in CH 4 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 carbon (K-MSC) with the least decrease of adsorptive capacity of CO 2 ....
