Abstract
Abstract A method of preparing an extruded catalyst composition. An acidic alumina hydrosol is admixed with a dry mixture consisting essentially of a finely divided alumina and a finely divided crystalline aluminosilicate. The resulting mixture is extruded, dried and calcined to yield a catalyst particularly useful for the selective reforming of a naphtha fraction to produce a high octane reformate product and a liquid petroleum gas.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
A method of preparing an extruded catalyst composition which comprises: a. admixing an acidic alumina hydrosol with a dry mixture consisting essentially of a finely divided alumina and a finely divided cyrstalline aluminosilicate, said crystalline aluminosilicate comprising from about 0.5 to about 20 wt. % of said dry mixture, and said hydrosol component comprising from about 2 to about 10 wt. % of the resulting mixture; b. extruding said resulting mixture while the last-mentioned component thereof is still in the hydrosol form; and c. drying and calcining the extrudate.
Claim 2
Independent Claim
89 words
A method of preparing an extruded catalyst composition which comprises: a. admixing an acidic alumina hydrosol with a dry mixture consisting essentially of a finely divided alumina and a finely divided cyrstalline aluminosilicate, said crystalline aluminosilicate comprising from about 0.5 to about 20 wt. % of said dry mixture, and said hydrosol component comprising from about 2 to about 10 wt. % of the resulting mixture; b. extruding said resulting mixture while the last-mentioned component thereof is still in the hydrosol form; and c. drying and calcining the extrudate.
Claim 3
Dependent Claim
22 words
The method of claim 1 further characterized in that said finely divided alumina comprises at least about 50 wt. % alpha-alumina monohydrate.
Claim 4
Dependent Claim
22 words
