CATALYST, METHOD FOR PREPARATION THEREOF, AND A PROCESS OF DEHYDROGENATION OF C-C-PARAFFIN HYDROCARBONS INTO OLEFINS Russian patent published in 2008 - IPC B01J23/26 B01J23/10 B01J23/04 B01J21/02 B01J35/02 B01J37/02 C07C5/333 B82B1/00 

FIELD: petrochemical processes and catalysts.

SUBSTANCE: invention relates to the area of production of olefin hydrocarbons via catalytic dehydrogenation of corresponding C₃-C₅-paraffin hydrocarbons and can be applied in chemical and petrochemical industries. C₃-C₅-Paraffin hydrocarbon dehydrogenation catalyst is described containing chromium oxide, alkaline metal oxide, transition metals, and carrier, said carrier being nanostructured oxygen-containing aluminum compound of general formula: Al₂O₃-_x(OH)_x*nH₂O, wherein x=0-0.28 and n=0.03-1.8, consisting of nanostructured primary particles 2-5 nm in size and characterized by disordered/imperfect layered structure similar to byerlyte structure. Method of preparing this catalyst as well as process of dehydrogenating C₃-C₅-paraffin hydrocarbons into olefins are also described, the latter being conducted in fluidized bed of described catalyst, which is recycled within the circuit: dehydrogenation reactor - regeneration reactor.

EFFECT: increased mechanical strength at high catalytic activity and stability.
