Title: Methanol and methyl fuel catalysts. Calendar year report, September 1978-November 1979

Abstract

Results of diffuse reflectance studies and quantitative x-ray powder diffraction measurements support the proposal that Cu/sup +//ZnO solid solution is the catalytically important moiety in low pressure methanol synthesis catalysts. Decreasing the CO/sub 2/ concentration in the syngas from 6% to less than or equal to 2% resulted in a slight improvement in methanol yield with th Ce-based Cu/ZnO catalysts. However, a similar decrease in CO/sub 2/ concentration led to a decrease in carbon conversion to methanol over Al-based Cu/ZnO catalysts. This difference in kinetic behavior shows a remarkable influence of the support on the course of the synthesis. The dependence of reaction rates on CO/sub 2/ concentration is actively investigated for these catalysts and for La-based ternary catalysts, as well as for binary and ternary catalysts doped with alkali metal ions such as Rb/sup +/. Although the effects of CeO/sub 2/, Al/sub 2/O/sub 3/ and La/sub 2/O/sub 3/ on the methanol synthesis kinetics in the presence of CO/sub 2/ are very marked, these oxides do not appear to change the composition of the product and all catalysts investigated here are still highly selective to methanol.
