Propane dehydrogenation process and polypropylene manufacturing process

A propane dehydrogenation process is characterized in that it comprises the following steps:

• a) providing a stream comprising at least propane;
• b) providing at least one proton-conducting catalytic membrane, each proton-conducting catalytic membrane comprising an anode, an electrolyte layer disposed on top of the anode and a porous cathode disposed on top of the electrolyte layer, wherein the anode comprises one or more channels, each of said channels comprising at least one dehydrogenation catalyst;
• wherein said one or more channels are flared depth channels or rectangular channels, and wherein said one or more channels are made in copper or steel;
• c) feeding within the anode of said one or more proton-conducting catalytic membranes under propane dehydrogenation conditions the stream provided at step (a);
• d) recovering a first effluent comprising at least propylene;
• e) optionally, recovering a second effluent comprising hydrogen.
