WEAR-RESISTANT COPPER-CONTAINING CATALYST FOR LOW-TEMPERATURE SYNTHESIS OF METHANOL AT LOW PRESSURE Russian patent published in 2006 - IPC B01J23/72 B01J23/80 B01J23/86 B01J21/02 B01J21/10 C07C29/154 C07C31/04

Abstract RU 2279915 C1

FIELD: industrial organic synthesis catalysts.

SUBSTANCE: invention relates to copper-containing catalysts for low-temperature synthesis of methanol in fluidized bed at low pressure and provides a wear-resistant catalyst, whose preparation involves impregnation and which contains oxides of copper, zinc, chromium, magnesium, aluminum, and boron and has following molar ratio: CuO:ZnO:Cr₂O₃, MgO:Al₂O₃:B₂O₃ = 1:0.3:(0.15-0.2):(0.1-0.025):(0.25-0.3):(0.08-0.1).

EFFECT: increased mechanical strength and wear resistance of catalyst.
