Abstract
Abstract A composition of matter having high catalytic activity, especially for cracking hydrocarbons, is prepared by intimately mixing from 15 to 80 percent by weight of synthetically produced interstratified montmorillonite-mica-like silicate mineral, exemplified by that obtainable in accordance with U.S. Pat. Nos. 3,252,757 and 3,252,889; from 1 to 40 percent of faujasite, natural or synthetic, having a silica-to-alumina ratio within the range of about 3 to about 6 1/2; and from 5 up to about 70 percent of a silicate material chosen from the class consisting of kaolinite, metakaolinite, halloysite, metahalloysite, and montmorillonite, and mixtures thereof, said mixing being carried out in an aqueous slurry with the base-exchangeable components in their ammonium form, followed by drying and calcining and grinding.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
48 words
A COMPOSITION OF MATTER ADAPTED FOR THE PRODUCTION OF HYROCARBON CRACKING CATALYST CONSISTING ESSENTIALLY OF COHERENT PARTICLES OF AN INTIMATE INTERMIXTURE OF FROM ABOUT 15 TO ABOUT 80 PERCENT BY WEIGHT OF A SYNTHETIC CLAY-TYPE MINERAL SELECTED FROM THE CLASS CONSISTING OF A FIRST SPECIES HAVING THE COMPOSITION:
Claim 2
Dependent Claim
48 words
A COMPOSITION OF MATTER ADAPTED FOR THE PRODUCTION OF HYROCARBON CRACKING CATALYST CONSISTING ESSENTIALLY OF COHERENT PARTICLES OF AN INTIMATE INTERMIXTURE OF FROM ABOUT 15 TO ABOUT 80 PERCENT BY WEIGHT OF A SYNTHETIC CLAY-TYPE MINERAL SELECTED FROM THE CLASS CONSISTING OF A FIRST SPECIES HAVING THE COMPOSITION:
Claim 3
Dependent Claim
63 words
A process for the production of the composition of matter of claim 1 which comprises admixing the individual components in comminuted form with sufficient water to form a slurry therewith, agitating said slurry until compositional homogeneity is obtained therein, and thereafter drying said slurry so as to produce solid particles having an essentially spherical form and exhibiting said compositional homogeneity within said particle.
Claim 4
Dependent Claim
61 words
A hydrocarbon cracking catalyst consisting essentially of coherent particles, said particles consisting essentially of an intimate intermixture of from about 15 to about 80 percent by weight of a synthetic clay-type mineral selected from the class consisting of a first species having the composition: 2.4 to 3.0 SiO.sub.2 :Al.sub.2 O.sub.3 :0.2 to 0.6 AB kSiO.sub.2 :Al.sub.2 O.sub.3 :0.4 to 0.8 AB
Claim 5
Dependent Claim
61 words
A hydrocarbon cracking catalyst consisting essentially of coherent particles, said particles consisting essentially of an intimate intermixture of from about 15 to about 80 percent by weight of a synthetic clay-type mineral selected from the class consisting of a first species having the composition: 2.4 to 3.0 SiO.sub.2 :Al.sub.2 O.sub.3 :0.2 to 0.6 AB kSiO.sub.2 :Al.sub.2 O.sub.3 :0.4 to 0.8 AB
Claim 6
Dependent Claim
39 words
A catalyst in accordance with claim 3 wherein said faujasite is selected from the class consisting of decationized faujasite and faujasite containing cations selected from the class consisting of hydrogen, magnesium, calcium, rare earth metal cations, and mixtures thereof.
Claim 7
Dependent Claim
40 words
A catalyst in accordance with claim 4 in which said magnesium, calcium, and rare earth metal cations are present in a total amount of from about 2 to about 100 percent of the total cation exchange capacity of said faujasite.
Claim 8
Dependent Claim
46 words
A process for the production of a hydrocarbon cracking catalyst which comprises the step of calcining the composition of matter of claim 1 at a temperature within the approximate range of about 1,200.degree.F. to about 1,500.degree.F. until said composition is substantially free of water and ammonia.
Claim 9
Dependent Claim
34 words
The process in accordance with claim 6 in which said calcining step is followed by treating with steam for a plurality of hours at a temperature within the range specified for said calcining step.
