Claims
- 1. A catalyst suitable for the hydroalkylation of an aromatic hydrocarbon comprising(a) a first metal having hydrogenation activity and selected from palladium, ruthenium, nickel, or cobalt; (b) a second metal, different from the first metal, selected from zinc, tin, nickel or cobalt; and (c) a crystalline inorganic oxide material having an X-ray diffraction pattern including the following d-spacing maxima 12.4±0.25, 6.90±15, 3.57±0.07 and 3.42±0.07, wherein the crytalline inorganic material excludes MCM-22.
- 2. The catalyst of claim 1 wherein the crystalline inorganic oxide material is selected from PSH-3, SSZ-25, MCM-36, MCM-49 and MCM-56.
- 3. A catalyst suitable for the hydroalkylation of an aromatic hydrocarbon comprising:ruthenium; tin; and a crystalline inorganic oxide material having an X-ray diffraction pattern including the following d-spacing maxima 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07, wherein the crystalline inorganic oxide material is selected from PSH-3, SSZ-25, MCM-36, MCM-49 or MCM-56.
- 4. A catalyst suitable for the hydroalkylation of an aromatic hydrocarbon comprising(a) a first metal having hydrogenation activity and selected from palladium, ruthenium, nickel, or cobalt; (b) a second metal, different from the first metal, selected from zinc, tin, nickel or cobalt; and (c) a crystalline inorganic oxide material having an X-ray diffraction pattern including the following d-spacing maxima 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07, wherein the crystalline inorganic oxide material is selected from PSH-3, SSZ-25, MCM-36, MCM-49 or MCM-56.
