3results about "Organic dehydrogenation" patented technology

We provide a technology to improve the heat resistance of dehydrogenation catalysts. The dehydrogenation catalyst is a compound represented by the general formula (A 1-x A' x )(Zr 1-y-z B y B' z )O 3-δ (wherein A is at least one element selected from alkaline earth metals, A' is at least one element of La and Y, B is at least one element of Ti and Ce, and B' is at least one element selected from Y, Sc, Yb, Al, In, and Nd, satisfying 0≦x≦0.4, 0.3≦(1-z)≦1, 0≦y, 0<(1-yz), and δ represents the amount of oxygen vacancy), and a subphase composed of at least one of three composite oxides represented by the general formulas AB'2O4, A2B'2O5, and A3B'4O9.

The present disclosure provides a method of operating a dehydrogenation reactor requiring vacuum pressure during the dehydrogenation reaction, the method including feeding a hydrocarbon to a reactor comprising a catalyst bed and configured to dehydrogenate the hydrocarbon under vacuum pressure; purging the reactor to remove remaining hydrocarbon; regenerating the catalyst bed with air from a regeneration air source; and evacuating the reactor to induce vacuum pressure, wherein the evacuating comprises passing a motive gas through a reactor evacuation ejector in fluid connection with the reactor, wherein the motive gas is nitrogen or air in the absence of steam. A system for dehydrogenation of a hydrocarbon is also provided, which includes a dehydrogenation reactor and a reactor evacuation ejector in fluid communication with the dehydrogenation reactor and a motive gas source, wherein the motive gas is nitrogen or air in the absence of steam.
