Claims
- 1. A dual-function chlorination-condensation catalyst composition consisting essentially of (a) Deacon-type catalyst comprising cupric halide, alkaline earth halide and/or alkali metal halide, and/or rare earth metal halide and (b) crystalline aluminosilicate zeolite component having a silica to alumina ratio of at least 12 and constraint index of 1 to 12.
- 2. The catalyst composition of claim 1 wherein the Deacon-type catalyst comprises about 1 to 20 weight percent of the zeolite component.
- 3. The catalyst composition of claim 2 wherein the dual function catalyst contains 10 to 90 weight percent alumina binder.
- 4. The catalyst composition of claim 2 wherein the zeolite consists essentially of acidic ZSM-5, having a silica:alumina mole ratio greater than 30:1.
- 5. The dual-function catalyst of claim 4 wherein the Deacon-type catalyst is deposited on alumina and composited with HZSM-5 crystals.
- 6. The catalyst composition of claim 1 wherein the Deacon-type catalyst include CuCl.sub.2, alkali metal or alkaline earth chloride, and rare earth chloride impregnated on alumina.
- 7. A dual function composite catalyst comprising an intimate mixture of a Deacon-type catalyst and a medium pore acid ZSM-5 type zeolite catalyst.
- 8. The component catalyst of claim 7 wherein the zeolite comprises a crystalline aluminosilicate having a silica:alumina mole ratio of at least 30:1 and a constraint index of about 1 to 12.
