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．
The reactivity of one-step synthesis of methyl isobutyl ketone from hydroquinone over Ni2 + and Pd-supported catalysts was investigated. The effects of different Ni content and Pd content on the activity were investigated. The results show that the addition of different contents of SiO2 in the carrier Al2O3 can improve the performance of the catalyst. The addition of La or Ce in the Ni / Al2O3 catalyst can improve the stability of the catalyst.
