Abstract
An aromatic hydrocarbon is contacted under suitable hydroalkylation conditions with a composition comprising a calcined, acidic, nickel and rare earth-treated crystalline zeolite.
Claims5
A process of preparing a highly active hydroalkylation catalyst, said process comprising:
- ion exchanging a crystalline zeolite with rare earth, nickel and ammonium cations;
- and
- calcining the ion exchanged crystalline zeolite in the presence of air at a temperature essentially maintained in the range of between about 150.degree. C. to about 400.degree. C.
