Patent ID: 8765082

Claim:
A system for dehydrogenation of a hydrocarbon stream comprising: (a) a dehydrogenation reactor containing an oxygen-selective membrane that separates the reactor into first and second gas passages, the oxygen-selective membrane being configured to transport oxygen from the second gas passage to the first gas passage; (b) a first reactor inlet configured to feed hydrocarbon feedstock and carbon dioxide into the first gas passage; (c) a second reactor inlet configured to feed oxygen into the second gas passage for subsequent transport through the oxygen-selective membrane; (d) a carbon dioxide oxidative dehydrogenation catalyst disposed in the first gas passage to react carbon dioxide, oxygen and hydrocarbon to produce a dehydrogenation product stream, and (e) a separation section including a first separator configured to separate the dehydrogenation product stream into a dehydrogenated hydrocarbon product stream, an unreacted hydrocarbon stream, and an offgas stream comprising carbon monoxide and carbon dioxide, and a second separator-configured to separate carbon monoxide in the offgas stream from carbon dioxide.
