Claims
- 1. A process for converting hydrocarbons by contacting a feed with a solid acid catalyst to generate a converted product, the catalyst comprising a support comprising a tungstated oxide or hydroxide of at least an element of Group IVB (IUPAC 4) of the Periodic Table, a first component selected from the group consisting of at least one Group IVA (IUPAC 14) component, at least one Group VA (IUPAC 15) component, and mixtures thereof, and a second component selected from the group consisting of platinum-group metals and mixtures thereof.
- 2. The process of claim 1 wherein the hydrocarbon conversion process is selected from the group consisting of cracking, hydrocracking, aromatic alkylation, isoparaffin alkylation, isomerization, polymerization, reforming, dewaxing, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, dehydration, hydrotreating, hydrodenitrogenation, hydrodesulfurization, methanation, ring opening, and syngas shift.
- 3. A process for the isomerization of a paraffinic feedstock to obtain a product having an increased isoparaffin content comprising contacting the paraffinic feedstock in an isomerization zone maintained at isomerization conditions comprising a temperature from about 25° C. to about 300° C., a pressure from about 100 kPa to about 10 Mpa and liquid hourly space velocity from about 0.2 to about 15 hr−1 with a solid acid isomerization catalyst, comprising a tungstated oxide or hydroxide of elements of Group IVB (IUPAC 4) of the Periodic Table, a first component selected from the group consisting of at least one Group WVA (IUPAC 14) component, at least one Group VA (IUPAC 15) component, and mixtures thereof, and a second component selected from the group of platinum-group metals and mixtures thereof, and recovering an isoparaffin-rich product.
- 4. The process of claim 3 wherein free hydrogen is present in the isomerization zone in an amount from about 0.01 to about 20 moles per mole of C5+ hydrocarbons present in the zone.
- 5. The process of claim 3 wherein the isomerization conditions comprise a temperature from about 100° C. to about 250° C., a pressure from about 300 kPa to about 4 mPa, and a liquid hourly space velocity from about 0.5 to about 15 hr−1, and wherein free hydrogen is present in the isomerization zone in an amount from about 0.01 to about 20 moles per mole of C5+ hydrocarbons present in the zone.
- 6. The process of claim 3 wherein the isomerization catalyst further comprises a refractory inorganic-oxide binder.
- 7. The process of claim 6 wherein the refractory inorganic-oxide binder comprises alumina.
- 8. The process of claim 3 wherein the first component is selected from the group consisting of silicon, phosphorus or mixtures thereof and the second component is platinum.
- 9. The process of claim 3 wherein the catalyst further comprises a third component selected from the group consisting of iron, cobalt, nickel, rhenium, and mixtures thereof.
- 10. The process of claim 9 wherein the third component is iron in an amount from about 1 to about 5 mass-%.
- 11. The process of claim 3 further comprising using at least a portion of the isoparaffin-rich product to blend a gasoline product.
