TECHNOLOGICAL SCHEME OF NEW REACTOR OF DEHYDROGENATION OF PROPANE TO PROPYLENE Russian patent published in 2014 - IPC C07C5/333 C07C11/06 B01J8/18 B01J38/32 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of propane dehydrogenation, which includes passing of a preliminarily heated initial propane flow into a dehydrogenation reactor, mixing and interaction of the initial propane flow with a non-metallic fluidised catalyst, which contains zirconium oxide, in the dehydrogenation reactor, which represents a reactor of fast fluidisation with formation of a flow of a propylene-containing product. The catalyst is in the reactor with the average time of presence from 15 to 45 minutes; passing of a waste catalyst into a catalyst regeneration unit with formation of a flow of a regenerated catalyst; and passing the flow of the regenerated catalyst into the dehydrogenation reactor.

EFFECT: application of the claimed method makes it possible to increase the passing capability of the system.
