ABSTRACT:

Preliminary investigations of these manganese oxide materials show that the different oxides exhibit different selectivity toward methanol and other products. It seems that there is a correlation between the initial O/Mn ratio of the oxide and methanol selectivity. These conclusions are supported by the results displayed in Figures 1 and 2. The main product of the manganese oxide-catalyzed CO hydrogenation is methanol except on Mao, which shows the lowest methanol selectivity, but the highest CO(sub 2) yield. Preliminarily, the results suggest that the higher the O/Mn ratio of the precursor oxide, the higher will be the methanol selectivity, while the CO(sub 2) and methane selectivities will be lower. The higher CO(sub 2) and C(sub 2), C(sub 3) and C(sub 4) hydrocarbon selectivities over the Mao catalyst compared to the other manganese oxides tested, indicates that Mao acts more like a water-gas shift and Fischer-Tropsch catalyst.
