Abstract

Abstract: This study presents strategies capable to intensify the thermal dehydrogenation of propane (TDH) using integrated reactor concepts. An inert packed bed membrane reactor for distributed dosing of oxygen to realize the oxidative dehydrogenation (ODH) was studied and compared to a reactor with catalytically active membrane. The latter concept allows to combine TDH and ODH in one apparatus to overcome the chemical equilibrium by in situ conversion of the by‐product H2 using O2 or in a reverse water‐gas shift reaction by CO2 . If CO2 is used as active sweep gas the reactor offered better performance regarding yield and selectivity. Strategies for further thermal integration are discussed. Abstract : Different integrated reactor concepts for the dehydrogenation of propane are presented and compared. These concepts incorporate membranes for distributed reactant dosing of O2 /CO2 as well as the integration of thermal and oxidative dehydrogenation in one apparatus to enhance selectivity and yield of the overall process.
