Study on Ni-supported Bifunctional Basic Zeolite Catalyst
Abstract:
Ni-K/NaX catalysts were prepared by impregnating NaX with KOH and Ni(NO3)2 solution. The reducibility and the state of Ni species and the basicity of the samples were characterized by XRD、TPR、CO2-TPD and XPS techniques. It is shown that there is an interaction between metallic species and NaX, as well as KOH, which results in the easy reduction of Ni2+and the decrease in basicity of the sample. In the reaction of condensation of acetone to methyl isobutyl ketone(MIBK), the reason why a suitable balance between basicity and metallicity of catalysts is necessary for selective MIBK production has been revealed.
