Claims
- 1. A catalyst composition suitable for para-selective conversion of substituted aromatic compounds, said composition comprising a crystalline zeolite catalyst component characterized by a silica to alumina mole ratio of at least 12 and a constraint index within the approximate range of 1 to 12, said composition further having incorporated thereon at least 0.25 weight percent of a metal selected from iron, cobalt and combinations thereof and at least 0.25 weight percent of the element phosphorus, said metal and said phosphorus both being in the oxide form when combined with said catalyst composition.
- 2. The composition of claim 1 wherein said metal comprises between 1 and 20 weight percent of the zeolite catalyst composition.
- 3. The composition of claim 2 wherein said metal is iron.
- 4. The composition of claim 2 wherein said metal is cobalt.
- 5. The composition of claim 2 wherein said composition comprises a zeolite admixed with a binder therefor.
- 6. The composition of claim 3 wherein said zeolite is selected from the group consisting of ZSM-5, ZSM-11, ZSM-12, ZSM-23, ZSM-35, ZSM-38 and ZSM-48.
- 7. The composition of claim 4 wherein said zeolite is selected from the group consisting of ZSM-5, ZSM-11, ZSM-12, ZSM-23, ZSM-35, ZSM-38 and ZSM-48.
- 8. The composition of claim 5 wherein said zeolite is selected from the group consisting of ZSM-5, ZSM-11, ZSM-12, ZSM-23, ZSM-35, ZSM-38 and ZSM-48.
- 9. A catalyst composition suitable for para-selective conversion of substituted aromatic compounds, said composition comprising a crystalline zeolite catalyst component which is zeolite ZSM-5 and said composition further having incorporated thereon at least 0.25 weight percent of a metal selected from iron, cobalt and combinations thereof and at least 0.25 weight percent of the element phosphorus, said metal and said phosphorus both being in the oxide form when combined with said catalyst composition.
- 10. A catalyst composition suitable for para-selective conversion of substituted aromatic compounds, said composition comprising a crystalline zeolite catayst component which is ZSM-11 and said composition further having incorporated thereon at least 0.25 weight percent of a metal selected from iron, cobalt and combinations thereof and at least 0.25 weight percent of the element phosphorus, said metal and said phosphorus both being in the oxide form when combined with said catalyst composition.
