Claims
- 1. A method of increasing the BET micro pore volume and pore diameter of a catalytic material prepared from an inorganic oxide gel by incorporating into the catalyst mix, before drying and without subsequent removal, a calcium sulfate whisker fiber having a diameter less than about 5 microns, a length less than about 100 microns, and having a length to diameter ratio of at least about 3.
- 2. Method of claim 1 in which the amount of whisker fiber in the final catalyst is between 5 and 50%.
- 3. Method of claim 1 in which the whisker fiber is calcium sulfate anhydrite.
- 4. Method of claim 1 in which the whisker fiber is calcium sulfate hemihydrate.
- 5. Method of claim 1 in which the catalytic material contains a hydrous alumina.
- 6. Method of claim 1 in which the catalytic material contains a hydrous silica.
- 7. Method of claim 1 in which the catalytic material contains hydrous silica and alumina.
- 8. Method of claim 1 in which the catalytic material contains hydrous alumina and is activated with cobalt and molybdenum.
- 9. Method of claim 1 in which the catalytic material contains hydrous alumina and is activated with nickel and molybdenum.
- 10. Method of claim 1 in which the catalytic material contains hydrous alumina and is activated with zeolites to produce a catalytic cracking material.
- 11. Method of claim 1 in which the catalytic material contains hydrous silica and is activated with zeolites to produce a catalytic cracking material.
- 12. Method of claim 1 in which the catalytic material contains hydrous silica and alumina and is activated with zeolites to produce a catalytic cracking material.
- 13. A catalytic material of increased BET micro pore volume and pore diameter produced by the process of claim 1.
