CATALYST, METHOD FOR PREPARATION THEREOF, AND DIHYDROXYALKANE PRODUCTION PROCESS Russian patent published in 2007 - IPC B01J23/72 B01J37/18 B01J37/08 C07C29/136

Abstract RU 2290994 C1

FIELD: hydrogenation-dehydrogenation catalysts.

SUBSTANCE: invention provides copper and silica-based catalyst containing 22.5-53.0% copper. Catalyst is prepared by reductive thermal decomposition of copper silicate in hydrogen flow at 380-450°C. catalyst is used in dihydroxyalkane production processes carried out at 180-200°C.

EFFECT: increased activity and selectivity of catalyst.
