Abstract
Hydrocarbons are converted with a catalyst comprising an alumina-zeolite support, a Group VIII metallic component and a Group VI-B metallic component. Key features of the process are the commingling of alumina and zeolite before the rare earth exchange of the faujasite and the extremely low sodium concentration of the finished catalyst.
Claims14
A process for the conversion of a hydrocarbon at hydrocarbon conversion conditions which comprises contacting said hydrocarbon with a catalyst prepared by a method comprising:
- (a) extruding alumina and a sodium form zeolite;
- (b) calcining the resulting extrudate;
- (c) contacting the resulting calcined extrudate with a sodium ion exchange solution to reduce the sodium concentration of said extrudate;
- (d) contacting the resulting extrudate from step c) with a rare earth salt solution;
- (e) calcining the resulting extrudate from step d);
- (f) contacting the resulting calcined extrudate from step e) with a sodium ion exchange solution to further reduce the sodium concentration of extrudate to less than about 0.5 wt. %;
- and
- (g) incorporating at least one metal component selected from Group VI-B and at least one metal component selected from Group VIII on the resulting extrudate from step f).
A process for the hydrocracking of a hydrocarbon oil comprising contacting the hydrocarbon oil under hydrocracking conditions at an elevated temperature and pressure with a hydrocracking catalyst prepared by a method comprising:
- (a) extruding alumina and a sodium form zeolite;
- (b) calcining the resulting extrudate;
- (c) contacting the resulting calcined extrudate with a sodium ion exchange solution to reduce the sodium concentration of said extrudate;
- (d) contacting the resulting extrudate from step (c) with a rare earth salt solution;
- (e) calcining the resulting extrudate from step (d);
- (f) contacting the resulting extrudate from step (e) with a sodium ion exchange solution to further reduce the sodium concentration of the extrudate to less than about 0.5 wt. %;
- and
- (g) incorporating at least one metal component selected from Group VI-B and at least one metal component selected from Group VIII on the resulting extrudate from step (f).
