Title:
OXIDE CATALYST, PRODUCTION THEREOF, AND CATALYTIC HYDROGENATION OF CO2 USING SAME
Document Type and Number:
WIPO Patent Application WO/1993/003837
Kind Code:
A1
Abstract:
A composite oxide, CuO-ZnO-Cr2O3-Al2O3-La2O3, having an La2O3 content of 4 wt.% is produced by physically mixing a composite oxide X1 having a composition of CuO-ZnO-Cr2O3-Al2O3 with another composite oxide X2 prepared by impregnating gamma-Al2O3 with La(NO3)3 and firing the mixture. Methanol can be obtained in a high yield by reducing the produced composite oxide, packing the reduced oxide in a reactor, and feeding a gaseous mixture of CO2 and H2 (in a molar ratio of 1 to 3) thereinto. The total conversion of CO2 is 31.0 % and the conversion into methanol is 22.9 %, i.e., the methanol selectivity is 73.9 %. When the pressure is 80 atm, the conversion of CO2 amounts to 39 % and the conversion into methanol amounts to 29 %.
