Claims
- 1. A hydrocarbon conversion process comprising contacting a hydrocarbon stream with a catalytic composite at hydrocarbon conversion conditions to give a converted product, the hydrocarbon conversion process selected from the group consisting of alkylation of aromatics, alkylation of isoparaffins, transalkylation of aromatics and isomerization of aromatics and the catalytic composite comprises a zeolite selected from the group consisting of UZM-8, UZM-8HS and mixtures thereof: where UZM-8 has a layered framework of at least AlO2 and SiO2 tetrahedral units and a composition on an as-synthesized and anhydrous basis expressed by an empirical formula of:
- 2. The process of claim 1 where the hydrocarbon conversion process is alkylation of aromatics.
- 3. The process of claim 1 where the hydrocarbon conversion process is transalkylation of aromatics.
- 4. The process of claim 1 where the hydrocarbon conversion process is isomerization of aromatics and the catalytic composite further comprises at least one platinum group metal.
- 5. The process of claim 1 where the hydrocarbon conversion process is alkylation of isoparaffins.
- 6. The process of claim 2 wherein the alkylation process comprises monoalkylation of aromatic compounds where an alkylatable aromatic compound is reacted with an olefin under alkylation conditions to provide an alkylated compound.
- 7. The process of claim 6 where the aromatic compound is benzene, the olefin is propylene and the alkylated compound is cumene.
- 8. The process of claim 6 where the alkylatable aromatic compound is selected from the group consisting of benzene, naphthalene, anthracene, phenanthrene and substituted derivates thereof.
- 9. The process of claim 6 where the olefin contains from 6 up to about 20 carbon atoms.
- 10. The process of claim 3 where the polyalkylated aromatic compound is a polyisopropyl benzene and the nonalkylated aromatic compound is benzene.
- 11. The process of claim 4 where the hydrocarbon stream comprises a non-equilibrium mixture of xylenes and ethylbenzene.
- 12. The process of claim 4 where the platinum group metal is platinum and is present from about 0.01 to about 5 mass-% of the catalytic composite on an elemental basis.
- 13. The zeolite of claim 1 where the zeolite is thermally stable up to a temperature of about 600° C.
- 14. The zeolite of claim 1 where M is selected from the group consisting of lithium, sodium, cesium, strontium, barium and mixtures thereof.
- 15. The zeolite of claim 1 where R is selected from the group consisting of diethyldimethylammonium, ethyltrimethylammonium, hexamethonium and mixtures thereof.
- 16. The zeolite of claim 1 where “m” is zero.
