Abstract

The present invention relates to a catalyst precursor composition comprising a first component having active sites, said first component being at least one of the surface modified clay and/or pore modified zeolite; and a second component being metal species comprising of at least one metal selected from Group VI B and at least one metal selected from VIII B and the second component is in intimate contact with the active sites of the first component. The present invention also provides a process for preparing the catalyst precursor composition. The present invention also relates to a catalyst composition and process of preparation thereof by using the catalyst precursor. More particularly, the present invention provides a catalyst composition suitable for converting hydrocarbon feeds to diesel range product.

First claim

We claim:

1. A catalyst precursor composition comprising:
a. a first component comprising active sites, said first component being a surface modified clay and a pore modified zeolite, and
b. a second component being metal species comprising of at least one metal selected from Group VI B and at least one metal selected from VIII B;
wherein the second component is in intimate contact with the active sites of the first component;
wherein the surface modified clay is obtained by calcination at a temperature in the range of 500° C. to 1000° C., followed by controlled acid leaching of a kaolin clay and the pore modified zeolite is obtained by controlled acid leaching of a faujasite zeolite.

2. The catalyst precursor composition as claimed in claim 1 , wherein the second component is present in an amount of 1 to 30 wt %, of the total weight of the catalyst precursor composition.

3. The catalyst precursor composition as claimed in claim 2 , wherein the second component is present in an amount of 5 to 25 wt % of the total weight of the catalyst precursor composition.

4. The catalyst precursor composition as claimed in claim 2 , wherein the second component is present in an amount of 10 to 20 wt % of the total weight of the catalyst precursor composition.

5. The catalyst precursor composition as claimed in claim 1 , wherein the ratio of Group VIII B metal to total metal component comprising both Group VIB and VIIIB metals is from 0.1:1 to 0.5:1.

6. The catalyst precursor composition as claimed in claim 1 , wherein the ratio by weight of the surface modified clay to the pore modified zeolite is in the range of 1:1 to 9:1.

7. The catalyst precursor composition as claimed in claim 1 , wherein the ratio by weight of the surface modified clay to the pore modified zeolite is in the range of 1.5:1 to 6:1.

8. The catalyst precursor composition as claimed in claim 1 , wherein the ratio by weight of the surface modified clay to the pore modified zeolite is in the range of 2:1 to 4:1.

9. The catalyst precursor composition as claimed in claim 1 , wherein the first component comprises a major amount of the surface modified clay and a minor amount of the pore modified zeolite.

10. The catalyst precursor composition as claimed in claim 1 , wherein the surface modified clay have mesopores with an average diameter in the range of 40 to 1000 Å.

11. The catalyst precursor composition as claimed in claim 1 , wherein the zeolite have primary pores and secondary pores, said primary pores having an average pore diameter in the range of 3 to 13.5 Å and said secondary pores having an average pore diameter in the range of 40 to 1000 Å.

12. A process for preparing a catalyst precursor composition as claimed in claim 1 , said process comprising treating said first component with a solution comprising said second component.

13. A hydroprocessing catalyst composition comprising: a catalyst precursor composition as claimed in claim 1 and a binder material, wherein the binder material is present in the range of 8 to 40% by weight of the catalyst composition.

14. A process for preparing a hydroprocessing catalyst composition, said process comprising of admixing a catalyst precursor composition of claim 1 with a binder in presence of a mineral acid and shaping to extrudates.
