The catalyst used for C_1-C_5 alcohols synthesis fromCO+H_2 was a mixture of oxides with Cu and Co as the main component, Fe··· etc as chain lengthening agent. Alkaline or alkaline earth metal are also added.Experimental results indicated that the composition and preparation procedure of the catalyst were of decisive importance for the formation of C_1-C_5 alcohols. The content of C_2~+ alcohols in product was especially dependant on the ratios of Cu/Co and Co/M.The distribution of products could be describ...
