摘要：
Selective hydrogenation of phenol to cyclohexanone was attempted using a catalytic palladium membrane reactor (CPMR) at atmospheric pressure and temperatures ranging from 150 to 300 degrees C. Four kinds of catalytic membranes made from palladium, Pd93Ni7, Pd93Ru7 and Pd77Ag23 were tested. The results showed the possibility of one-step production of cyclohexanone using the CPMR. Of all the membranes tested, pure palladium showed the highest activity for the production of cyclohexanone. The hydrogen permeating through the membranes was found to have higher reactivity than that pre-mixed into phenol.
