Title
Synthesis of higher alcohols from syngas over K/Co/β-Mo2C catalysts
Abstract

K/Co/β-Mo2C catalysts were prepared and tested for higher alcohols (C2+OH) synthesis (HAS). The catalysts exhibited high catalytic activity and selectivity to C2+OH. The effect of Co/Mo molar ratio in the catalysts upon the catalytic performance of HAS was investigated and the best one was at Co/Mo molar ratio of 1/8–1/6. It could be concluded that the Co promoter exerted strong promotion for carbon chain growth, especially for the stage of C1OH to C2OH. The XPS spectra revealed that there was a strong synergistic interaction between Co and Mo, and it depended strongly on the Co/Mo molar ratio. The new phases “Co3Mo3C” and “Co2C” formed over Co promoted K/β-Mo2C catalysts, which might be responsible for the high activity of higher alcohols and hydrocarbons synthesis, respectively.
