Abstract

See full text

In a process for activating a hydroalkylation catalyst, a catalyst precursor comprising a solid acid component and a compound of a hydrogenation metal is heated at a heating rate of less than 50° C./hour in the presence of hydrogen to an activation temperature in a range from 100° C. to 260° C. and then the heated catalyst precursor is treated with hydrogen for a duration effective to reduce at least a portion of the metal compound to an elemental form.
