Comparison of Alumina and Silica Supported Ni,Pd Catalysts in Synthesis of Methyl iso-Butylketone from Acetone and Hydrogen

Abstract

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.

Key words: Ni,Pd/Al₂O₃, Rare earth metal, Acetone, Methyl iso-butylketone
