С-С OLEFIN SYNTHESIS METHOD AND CATALYST TO THIS END Russian patent published in 2010 - IPC C07C5/333 B01J23/26 B01J21/04 B01J23/04 B82B1/00

Abstract RU 2402514 C1

FIELD: chemistry.

SUBSTANCE: invention relates to organic synthesis and specifically to synthesis of olefin and diene hydrocarbons through dehydrogenation of paraffin hydrocarbons. The invention describes a method for synthesis of C₃-C₅ olefins through dehydrogenation of paraffin hydrocarbons in the presence of a catalyst which contains chromium oxide, an alkali metal oxide, oxides of transition metals and a support. The raw material of the process is a mixture of C₁-C₅ paraffin hydrocarbons, where the said mixture may contain two to seven components.

EFFECT: higher overall conversion of C₃-C₅ paraffins to olefins, higher overall olefin selectivity of the process.
