PARAFFIN HYDROCARBON DEHYDROGENATION CATALYST Russian patent published in 2006 - IPC B01J23/26 B01J23/04 B01J21/04 B01J21/06 B01J23/70 C07C5/333

Abstract RU 2271860 C1

FIELD: hydrogenation-dehydrogenation catalysts.

SUBSTANCE: invention concerns catalysts for dehydrogenation of C₂-C₅-alkanes into corresponding olefin hydrocarbons. Alumina-supported catalyst of invention contains 10-20% chromium oxide, 1-2% alkali metal compound, 0.5-2% zirconium oxide, and 0.03-2% promoter oxide selected from zinc, copper, and iron. Precursor of alumina support is aluminum oxide hydrate of formula Al₂O₃·nH₂O, where n varies from 0.3 to 1.5.

EFFECT: increased mechanical strength and stability in paraffin dehydrogenation process.
