摘要：

In a previous paper, J. Membrane Sci., 60 (1991) 185-193, large separation factors (as high as 600) were reported for methanol/hydrogen mixtures. These reported results are not accurate. Repetition of the experiments gave separation factors between 1.5 and 4 depending on the total pressure at 473 K. The same experimental apparatus and alumina membranes were used in this study. These results indicate that capillary condensation in the membrane pores is not the primary separation mechanism as had been previously reported.
