Dehydrogenation of propane in a combined membrane reactor with hydrogen-permeable palladium module

Didenko, L. P. / Savchenko, V. I. / Sementsova, L. A. / Chizhov, P. E. / Bykov, L. A.

Abstract The basic features of the propane dehydrogenation reaction in a combined membrane reactor with a hydrogen-permeable palladium module and chromia-alumina catalyst (9.0 wt % Cr) in the temperature range of 520–580°C have been studied. Under optimum conditions (T, 550°C; propane space velocity and a stripping gas flow rate of 600–900 h−1 and 100–250 cm3/min, respectively), the feedstock conversion to propylene increases by a factor of 1.6–2.0. It has been suggested that compliance between the rate of H2 formation and its withdrawal through the membrane is of considerable importance.
