摘要
为了“优化燃料资源,创建能源化工体系”,开展甲醇下游产品的研究是当今燃料化工的重要内容之一。70年代初美国Monsanto开发的Rh-Ⅰ催化体系使甲醇液相羰基化制醋酸大规模工业化,由于该体系采用昂贵紧缺的金属铑,催化剂需精心回收;并且由于需要大量碘化...
A novel catalyst without any addition of promoter for direct vapor phase carbonylation of methanol was investigated Sulfided Mo/C catalyst was found to have a higher activity and selectivity after reduced in H2 atmosphere than sulfided Co/C and CoMo/C catalyst Under reaction temperature of 300 and space velocity of 3250L/(kgh), the conversion of MeOH and the selectivity of methyl acetate were 49% and 80% respectively, and the molar yield was 392% The experiment found direct reduced Mo/C catalyst (not be sulfidized) had lower activity for methanol carbonylation The spectra of XRD demonstrated that the novel sulfided-reduced Mo/C catalyst formed more H0.34MoO3 crystalline than the direct reduced Mo/C catalyst
