| Abstract: | The effects of preparation conditions of Ni/AC catalysts on catalyst performances in vapor phase carbonylation of methanol to acetic acid were observed with an atmospheric gas solid bed reactor It was found that the optimum calcination and reduction temperature are 400℃ and 700℃, respectively With the catalyst prepared in optimum conditions, the conversation of methanol was 50 54% and the yield of acetic acid was up to 23 37% |
