... Abstract Membrane technology has attracted more and more attentions in oil/gas industries. Most of the membranes separation are based on the difference in molecular dimensions (or the mechanism of molecular sieving). However, this work reports the reverse-selectivity based on the permeation...

... Abstract Carbon molecular sieve membranes (CMSM) were derived from the pyrolysis of polymeric precursors at 3 different pyrolytic temperatures (600, 700, and 800°C), respectively. The CMSM samples were characterized and tested for the permeation of 4 pure gases (CH 4 , CO 2 , N 2 and He...

... were synthesized at different pyrolytic conditions and examined for separation of N 2 /CH 4 gas pair. Adsorption and permeation experiments were conducted to examine the separation performance of each membrane sample. At the ambient conditions, a perm-selectivity of ~ 6 was found for (N 2 /CH 4 ) pair...

... to be an activated process. Activation energies for diffusion through the silica membrane calculated from the slopes of Arrhenius plots of the permeation data ranged from 4.61 10 14.0 kcal/mole and correlate well with the kinetic diameter of the penetrants. Large separation factors were obtained for the penetrants...
