Abstract Under pressurized conditions in the presence of methyl iodide,Ni,Zn and Cu loaded on the activated carbon has better catalytic activity in the vapor phase carbonylation of methanol to acetic acid,the catalysts were charactered by means of BET,XRD and TPR,the ratios of the three metals loaded were studied.The results indicated that the three metals had synergistic effect,the addition of Cu,Zn to Ni/AC could improve the catalytic activity,the appropriate ratio of the three metals was 5% Ni-5%Zn-5% Cu(wt),under the optimal conditions,conversion of methanol reached to 9458%,yield of acetic acid was 1658%,and the total yield of carbonyl products was 5126%.And the following carbonyl process evaluations showed that,the selectivity of carbonic products and yield of acetic acid were not only depended on the contact time and reaction temperature,but also related to the feed ratio of n (CH3OH/CH3I),n(CO/CH3OH).
