Reduced Mo-KCl/SiO2 catalysts were effectively activated for synthesis of C1-C9 hydrocarbons with CO-rich (CO/H2=3/1) synthesis gas at 573K. This treatment, which caused but slight change in alcohol productivity, was contrasted with the treatment with CO/H2=1/1 synthesis gas, that was effective in enhancing selective alcohol synthesis; the CO/H2 ratio of the synthesis gas used for pretreatment was crucial to determining hydrocarbon/alcohol selectivity. The enhanced activity for hydrocarbon synthesis might be related with the formation of MoC. This activation treatment proved to be much more effective than the n-C4H10/H2 treatment.
