Abstract: The disclosure concerns a propane dehydrogenation process, remarkable in that it comprises the steps of (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 at least one dehydrogenation catalyst; (c) feeding within the anode of said one or more proton-conducting catalytic membranes under propane dehydrogenation conditions the stream provided at step (a); and (d) recovering a first effluent comprising at least propylene. The disclosure also concerns a polypropylene manufacturing process and an installation to conduct said process.

Abstract: The disclosure concerns a proton-conducting catalytic membrane remarkable in that it comprises 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 at least one dehydrogenation catalyst and is devoid of pores, and wherein the electrolyte layer comprises one or more perovskite materials with one or more cations selected from Ba, Ce, Zr, Y, La, Sr, Mn, Fe, Eu, Tb, Ni, Yb, Pr, Sm, Zn, Gd, Er, Co, Nd, or any mixtures thereof. The disclosure is also about a dehydrogenation reactor comprising such proton-conducting catalytic membrane as well as to method for making such proton-conducting catalytic membrane.
