Uptake of isobutane

Thus, with the ratio jin/jos directly following from Eqs. 17 and 20, the sticking probability , i.e., the probability that a molecule, after having encoim-tered the outer crystal surface, is going to continue its trajectory in the intracrystalhne pore space, has become accessible by direct experimental determination. Eor the systems considered in Sects. 3.3.2 and 3.3.4 under the conditions of the reported experiments, i.e., for molecular uptake of isobutane by silicalite-1 at a pressure of 1 mbar and of methanol by ferrierite at a pressure of 10 mbar, it results to be 0.01 and 6 x 10 , respectively. Thus, it...
