Yoo, K Tsekov, R Smirniotis, PG 2024-01-21T07:43:42Z 2024-01-21T07:43:42Z 2021-09-01 2003-12-11 1520-6106 https://pubs.kist.re.kr/handle/201004/138003 The intra-crystalline diffusion of normal alkanes in LTL and ZSM-12 zeolite was experimentally studied via gravimetric measurements performed at different temperatures. A periodic dependence of the diffusion coefficient on the number of carbon atoms in alkane was detected, which is an experimental proof for resonant diffusion. The present observations were described on the base of the existing theory of the resonant diffusion and several important parameters of the alkane-zeolite interaction and zeolite vibrations were obtained. In the considered temperature region the diffusion coefficient follows the Arrhenius law with periodic dependences of the preexponential factor and activation energy on the number of carbon atoms in alkanes. A compensation effect of simultaneous increases of the preexponential factor and the activation energy was also established.
