<p>The specification discloses a catalyst and a process for hydroalkylating aromatic hydrocarbons. The catalyst comprises a molecular sieve material having an acid function, a hydrogenation component and a shape selective function. The sieve material has a pore size that is capable of accommodating molecules of the products and excluding molecules of reactants that are too large. Sieve materials described include zeolite types X and Y, ZSM 20 and zeolite beta. The hydrogenation component includes copper and/or nickel and/or a rare earth metal. Promoters for the catalyst include ruthenium and platinum. The process involves contacting a stream of aromatic hydrocarbons with hydrogen in the presence of the catalyst under hydroalkylation conditions.</p> |
