摘要

As for the method of producing the cobalt based huitsushiyatoropushiyu synthetic catalyst precusor, general system (1): HOOC C*R1C*R2 COOH (1)[In formula, both C in C ^*R1 and C ^{*R2 * it} is sp² carbon, R₁ and R₂ differs the same or, from group where each one consists of hydrogen and organic basis it is selected]Multi functionality carboxylic acids or that precusor which it possesses, in the catalyst backing of granularity and/or the fact that it introduces on the catalyst backing is included. Ratio of the quantity of the multi functionality carboxylic acids which confront the backing surface area and use at least is the 0.3 mol carboxylic acid /m2 backing surface area. In the catalyst backing and/or simultaneously with the introduction of the carboxylic acid to on the catalyst backing, or after that, in the catalyst backing and/or the cobalt compound is introduced on the catalyst backing. Calcining the impregnation backing, you obtain the cobalt based huitsushiyatoropushiyu synthetic catalyst precusor. Selective figure Figure 1
