Abstract
A catalyst for producing phenol consisting essentially of a nickel compound supported on a metal oxide carrier, or a catalyst for producing phenol consisting essentially of iron oxide and nickel oxide, and processes for producing phenol using either of the above catalyst. The catalysts of the invention exercise a high conversion of benzoic acid and a high selectivity to phenol, and phenol can be produced in a high yield, particularly in a high space time yield through the processes of the invention using the above catalysts. The above conversion, selectivity and space time yield can be improved by calcining the catalyst at 600.degree. to 900.degree. C.
