本文报导了一种新型的甲醇羰基化生产乙酸的镍催化剂.由于选用了由聚偏二氯乙烯热裂解制得的特殊碳化物为载体,所以该催化剂有大比表面积,孔径分布均匀,并有优良的热稳定性和机械强度,其催化甲醇羰基化的速率在相对温和的条件下达到582克乙酸/克镍/时,高于文献报导的镍金属催化剂. In this paper, a new type of nickel catalyst for the production of acetic acid from methanol carbonylation has been reported. Due to the selection of a special carbide prepared by the pyrolysis of polyvinylidene chloride as the carrier, the catalyst has a large specific surface area, uniform pore size distribution, Excellent thermal stability and mechanical strength, which catalyzed the rate of methanol carbonylation at relatively mild conditions, reached 582 g acetic acid / g nickel / hour, higher than the reported nickel metal catalyst.
