Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
45 words
A cracking process comprising cracking a metal-free hydrocarbon feed in the presence of a fluidizable cracking catalyst composition containing a sepiolite, an ultrastable Y-zeolite, a clay selected from the group consisting of kaolin, bentonite, a layered clay and a montmorillonite clay, and a matrix material.
Claim 2
Dependent Claim
45 words
A cracking process comprising cracking a metal-free hydrocarbon feed in the presence of a fluidizable cracking catalyst composition containing a sepiolite, an ultrastable Y-zeolite, a clay selected from the group consisting of kaolin, bentonite, a layered clay and a montmorillonite clay, and a matrix material.
Claim 3
Dependent Claim
23 words
A process according to claim 1, characterized in that the sepiolite, the ultrastable Y-zeolite, and the clay are collectively incorporated in a matrix.
Claim 4
Dependent Claim
28 words
A process according to claim 2, characterized in that the sepiolite is present in the cracking catalyst composition in an amount of 5 to 70 percent by weight.
Claim 5
Dependent Claim
28 words
A process according to claim 3, characterized in that the sepiolite is present in the cracking catalysts composition in an amount of 20 to 30 percent by weight.
Claim 6
Dependent Claim
29 words
A process according to claim 1, characterized in that the ultrastable Y-zeolite is present in the cracking catalyst composition in an amount of 5 to 70 percent by weight.
Claim 7
Dependent Claim
29 words
A process according to claim 5, characterized in that the ultrastable Y-zeolite is present in the cracking catalyst composition in an amount of 20 to 40 percent by weight.
Claim 8
Dependent Claim
13 words
A process according to claim 1, characterized in that the sepiolite is non-dispersed.
Claim 9
Dependent Claim
