Abstract

The present invention provides a catalyst composition for use in a catalytic cracking process, said catalyst composition comprises 3.5 to 15.5% of pentasil zeolite, 9 to 40% of ultra-stable Y (USY) or rare earth exchanged USY (REUSY) zeolite, 3.5 to 15% of large pore active matrix based bottom up gradation component and 0.3 to 3% of a metal trap component, the percentage being based on weight of the catalyst composition. The present invention also provides a process for preparing the said catalyst composition and a catalytic cracking process comprising contacting the said catalyst composition with a feedstock.

First claim

What claimed is:

1. A catalyst composition for use in a catalytic cracking process, said catalyst composition comprising 3.5 to 15.5% of pentasil zeolite, 9 to 40% of ultra-stable Y (USY) or rare earth exchanged USY (REUSY) zeolite, 3.5 to 15% of large pore active matrix based bottom up-gradation component and 0.3 to 3% of a metal trap component, the percentage being based on weight of the catalyst composition and wherein the large pore active matrix based bottom up-gradation component comprises 40-60 wt % alumina, 5-25 wt % silica, 20-60 wt % clay, 1-20 wt % PO 4 and has a pore size in the range of 80 Å to 200 Å.

2. The catalyst composition as claimed in claim 1 , wherein the pentasil zeolite is in range of 4 to 8%, ultra-stable Y (USY) or rare earth exchanged USY (REUSY)
zeolite is in the range of 10 to 25%, large pore active matrix based bottom up gradation component is in the range of 6 to 15% and metal trap component is in range of 0.4 to 3%.

3. The catalyst composition as claimed in claim 1 , wherein the pentasil zeolite has a pore size in the range of 5.1 Å to 5.6 Å and is selected from a group comprising of ZSM-5 Zeolite, ZSM-11 Zeolite, ZSM-12 Zeolite, ZSM-22 Zeolite, ZSM-23 Zeolite, and ZSM-35 Zeolite.

4. The catalyst composition as claimed in claim 1 , wherein the REUSY zeolite comprises of 3 to 5 wt. % of a rare earth cation selected from a group comprising of rhenium, lanthanum, cerium, praseodymium, neodymium, samarium and gadolinium.

5. The catalyst composition as claimed in claim 1 , wherein the metal trap component
comprises at least one of a vanadium trap component and a nickel trap component wherein said vanadium trap component is selected from a group comprising of phosphorus, aluminium, lanthanum, cerium, rhenium, praseodymium, neodymium, samarium, gadolinium, tin, strontium, titanium, zirconium and silicon; and said nickel trap component is selected from a group comprising of cerium, antimony, bismuth, phosphorus, aluminium and silicon.

6. The catalyst composition as claimed in claim 1 , wherein a remaining amount is comprised of a binder and filler.

7. The catalyst composition as claimed in claim 6 , wherein the binder is selected from a group comprising of alumina, silica, silica-alumina and phosphate.

8. The catalyst composition as claimed in claim 6 , wherein the filler is selected from a group comprising of kaolin clay, montmorillonite clay, bentonite clay, laolinite clay and halloysite clay, aluminum trihydrate, bayerite, and gamma alumina.

9. The catalyst composition as claimed in claim 1 , wherein the catalyst composition is in the form of a composite catalyst or a mixture of additives.
