Abstract
An improved hydrocarbon reforming process comprising: 1. contacting a hydrocarbon feed with a platinum group metal, rhenium-containing catalyst in the presence of hydrogen in at least one reaction zone at a temperature in the range of about 500.degree. F. to about 650.degree. F. for a time sufficient to improve the catalytic activity stability of the catalyst; and thereafter, 2. contacting the hydrocarbon chargestock with the catalyst in the presence of hydrogen at hydrocarbon reforming conditions including a higher temperature than the temperature at which step (1) occurred.
Claims10
A hydrocarbon reforming process which comprises:
- 1. contacting a hydrocarbon feed with a catalyst comprising a major amount of a porous solid support, a minor catalytically effective amount of at least one platinum group metal component and a minor catalytically effective amount of at least one rhenium component in the presence of hydrogen in at least one reaction zone at hydrocarbon reforming conditions including a temperature in the range of about 500.degree. F. to about 650.degree. F. for a time sufficient to improve the catalytic activity stability of said catalyst;
- and thereafter,
- 2. contacting a hydrocarbon feed with said catalyst in the presence of hydrogen at hydrocarbon reforming conditions including a higher temperature than the temperature at which step (1) occurred.
