WEAR-RESULTANT COPPER-CONTAINING CATALYST FOR LOW-TEMPERATURE METHANOL SYNTHESIS AT HIGH-PRESSURE

摘要

FIELD: industrial organic synthesis catalysts.;SUBSTANCE: invention relates to copper-containing catalysts for low-temperature synthesis of methanol in fluidized bed at high pressure and provides catalyst, whose preparation involves impregnation and which contains oxides of copper, zinc, chromium, magnesium, aluminum, boron, and barium and has following molar ratio: CuO:ZnO:Cr₂O₃, MgO:Al₂O₃:B₂O₃:BaO = 1:(0.7-1.1):(0.086-0.157):(0.05-0.15):(0.125-0.2):(0.018-0.029):(0.04-0.075).;EFFECT: increased mechanical strength and wear resistance of catalyst.;1 tbl
