| 英文摘要 | Potassium-promoted beta-mo2c catalysts were prepared and their performances in co hydrogenation were investigated. the main products over -mo2c catalyst were cl-c,, hydrocarbons, only similar to 4 c-atom% alcohols were obtained. the products of hydrocarbons and alcohols obeyed traditional linear anderson-schultz-flory (a-s-f) distribution. however, modification with k2co3 resulted in a remarkable selectivity shift front hydrocarbons to alcohols. moreover, it was found that potassium promoter enhanced the ability of chain propagation of beta-mo2c catalysts and resulted in a higher selectivity to c2+oh. for k/beta-mo2c catalysts, the hydrocarbon products also obeyed traditional linear a-s-f plots, whereas alcohols gave a unique linear a-s-f distribution with remarkable deviation of methanol compared with that on beta-mo2c catalyst. it could be concluded that potassium promoter might exert a prominent function on the whole chain propagation to produce alcohols. a surface phase on the k/beta-mo2c catalysts such as the "k-mo-c" explained the higher value for c2+oh, especially could promote the step of c1oh to c2oh, or could have a role in producing directly c2oh, but again this would be speculative. at the same time, the influence of the loadings of k2co3 on the performances of p-mo2c catalyst was investigated and the results revealed that the maximum yield of alcohol was obtained at k/mo molar ratio of 0.2.
