The dehydrogenation of isobutane to isobutene was conducted in a comparatively low-temperature range (from 623 to 723 K) using a hydrogen-permeable membrane reactor. An Al,O,-supported platinum catalyst exhibited high activity compared with a commercial Cr,Oa-Al,Oa catalyst in a conventional flow re
Abstraet--A mathematical model for the startup period of a fixed-bed reactor with first-order reaction kinetics, axial dispersion and film mass transfer resistance was formulated and solved analytically using Laplace transform. The solution can be used to correlate or predict the reactant concentrat
