【摘要】 研究了Al2O3负载Ni、Pd催化剂上雨酮加氢一步合成甲基异丁基酮的反应活性，考察了不同Ni含量和不同Pd含量对活性的影响．结果表明，在载体Al2O3中加入不同含量的SiO2后，会改善载体的性能，Ni／Al2O3催化剂中添加稀土元素La或Ce后可改善催化剂的稳定性．更多还原

【Abstract】 Studies on the reaction of acetone and hydrogen to methyl iso-butylketone(MIBK)in one-step process over catalysts consisting of nickel and palladium loaded on alumina andsilica were performed. The effects of content of Ni and Pd on the reaction were investigated.Both Ni and Pd loaded catalysts. have exhibited good activity for this reaction, while higheractivity and better durability were achieved on the Pd-loaded catalysts. The addition of SiO2to Ni, Pd/Al2O3 could enhance the activity and selectivity, and especially the durability ofthe catalysts. It is also found that Ni/Al2O3 modified by rare earth metal of lanthanum andcerium could improve the activity of the catalysts.更多还原
