Claims
- 1. A reforming process comprising contacting mixed hydrocarbon fraction to obtain a higher-octane product at reforming conditions using a catalyst comprising amounts effective to render the catalyst active as a reforming catalyst of:
- (a) at least one MP-NZMS characterized in the calcined form by an adsorption of isobutane of at least 2 percent by weight at a partial pressure of 500 torr and a temperature of 20.degree. C. and also characterized by an adsorption of triethylamine less than about 5 percent by weight at a partial pressure of 2.6 torr and a temperature of 22.degree. C.;
- (b) an inorganic-oxide carrier;
- (c) a chlorine component; and
- (d) at least one group VII metal component.
- 2. The process according to claim 1 wherein the adsorption of triethylamine of the MP-NZMS is less than about 3 percent by weight.
- 3. The process according to claim 1 wherein the inorganic oxide comprises alumina.
- 4. The process according to claim 3 wherein the chlorine component is present on an elemental as is in the catalyst in an amount of between 0.1 and 2 wt. % of the alumina.
- 5. The process according to claim 1 wherein the MP-NZMS is present in the catalyst in an amount of between about 10 and 80 wt. %, based on the total weight of the carrier.
- 6. The process according to claim 1 wherein the Group VIII metal is present in the catalyst on an elemental basis in an amount of between about 0.1 and 2 wt. %, based on the weight of the carrier.
- 7. The process according to claim 1 wherein the Group VIII metal component comprises at least one platinum-group metal component.
- 8. The process according to claim 6 wherein the platinum-group metal component comprises a platinum component.
- 9. The process according to claim 6 wherein the catalyst further comprises a second metal component selected from the group consisting of rhenium, tungsten and tin components.
- 10. The process according to claim 9 wherein the weight ratio of the platinum-group metal to the second metal is between about 1:5 and 5:1 on an elemental basis.
- 11. The process according to claim 1 wherein the MP-NZMS is one or more selected from the group of silicoaluminophosphate molecular sieves.
- 12. The process according to claim 11 wherein the MP-NZMS is one or more from the group consisting of SAPO-11, SAPO-31, SAPO-40 and SAPO-41.
- 13. The process according to claim 1 comprising a dehydrocyclization process to obtain aromatic components at dehydrocyclization conditions.
- 14. A reforming process comprising contacting a mixed hydrocarbon fraction to obtain a higher-octane product at reforming conditions using a catalyst comprising amounts effective to render the catalyst active as a reforming catalyst of;
- (a) one or more MP-NZMSs selected from the group consisting of SAPO-11, SAPO-31, SAPO-40 and SAPO-41;
- (b) an alumina carrier;
- (c) a chlorine component present in an amount of between about 0.1 and 2 wt. % on an elemental basis, based on the weight of the carrier; and
- (d) at least one platinum group metal component.
