Abstract

Abstract In a method for activating a preformed, crystalline aluminum phosphate, the aluminum phosphate is combined with an activating metal oxide, such as silica, and water under conditions, such as mulling, sufficient to increase the acid catalytic activity of the material. The resultant activated phosphate is useful in hydrocarbon cracking.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 54 words
A method of increasing the acid catalytic activity of a crystalline aluminum phosphate catalyst, said method comprising combining: (i) a solid, microporous, crystalline aluminum phosphate material; (ii) an amorphous, activating metal oxide; and (iii) water wherein said aluminum phosphate material and said activating metal oxide are intimately ground in the presence of said water.
Claim 2
Independent Claim 54 words
A method of increasing the acid catalytic activity of a crystalline aluminum phosphate catalyst, said method comprising combining: (i) a solid, microporous, crystalline aluminum phosphate material; (ii) an amorphous, activating metal oxide; and (iii) water wherein said aluminum phosphate material and said activating metal oxide are intimately ground in the presence of said water.
Claim 3
Dependent Claim 20 words
A method according to claim 1, wherein said activating metal oxide is selected from SiO 2 and GeO 2 .
Claim 4
Dependent Claim 13 words
A method according to claim 1, wherein said activating metal oxide is silica.
Claim 5
Independent Claim 22 words
A method according to any preceding claim, wherein said components (i), (ii) and (iii) are further combined with (iv) a basic material.
Claim 6
Independent Claim 26 words
A method according to any preceding claim, wherein the activated catalyst is formed into a composite, said metallic oxide functioning as a binder for the composite.
Claim 7
Independent Claim 32 words
A method according to any preceding claim which further comprises the step of contacting the activated catalyst with steam under conditions sufficient to further increase the acid catalytic activity of the catalyst.
Claim 8
Dependent Claim 50 words
A process for cracking hydrocarbons comprising contacting the hydrocarbons with a catalyst activated by a method as claimed in any preceding claim at a temperature from 300 to 700°C, a pressure of 0.1 to 30 atmosphere (10 to 3039 kPa), and a weight hourly space velocity of 0.1 to 20.
Claim 9
Dependent Claim 29 words
A process as claimed in claim 7, wherein the hydrocarbons are in the form of a gas oil having a boiling range between 450 and 1000°F (232 and 538°C).
