Permeation and separation characteristics of selected zeolite MFI composite membranes were measured for the system of butane isomers. Flux, permeation and separation factors were measured as a function of feed pressure, temperature and feeding amount of butane isomers. The experiments, based on Wicke-Kallenbach method, were carried out using steady-state membrane apparatus MEMFIS. The observed fluxes and permeances of n-butane were higher in comparison with isobutane for all membranes. The separation factors exhibited the maxima in the dependence on temperature and decreased with increasing feed pressure. It follows from the comparison of single component and binary mixture experimental data that n-butane permeance was strongly reduced by the presence of isobutane as a co-permeating component in the binary mixture. However, isobutane was practically not influenced by the presence of n-butane.
