Abstract
A crystalline aluminosilicate zeolite catalyst made by a process comprising the steps of exchanging the zeolite, heating it, compositing the resulting product with a porous matrix and reexchanging the composite product is provided. The invention also provides a method of converting a hydrocarbon charge using such catalyst.
Claims15
A method of converting a charge of hydrocarbon material to hydrocarbon products which comprises contacting said charge under hydrocarbon conversion conditions with a crystalline zeolite catalyst composition prepared by:
- a. exchanging the zeolite with a solution containing at least one exchangeable cation to at least partially replace the original cation;
- b. heating the exchanged zeolite at a temperature of 500.degree. to 1600.degree.F;
- c. compositing the resulting zeolite with a porous matrix material;
- and
- d. contacting the resultant composite with a solution containing at least one exchangeable cation other than the original cation.
A method for cracking a hydrocarbon charge which comprises contacting said charge under catalytic cracking conditions with a crystalline zeolite-containing catalyst composition prepared by:
- a. contacting the crystalline zeolite with a solution which includes a salt of a rare earth cation;
- b. heating the exchanged zeolite at a temperature of 500.degree. to 1600.degree.F;
- c. compositing the resulting zeolite with a porous matrix material;
- and
- d. contacting the resultant composite with a solution which includes an ammonium salt.
