Abstract
Abstract Ferrierite ore is activated for normal paraffin conversion by exchanging with the ammonium ion, heating in air at a temperature from about 775 DEG F to about 1000 DEG F and exchanging again with the ammonium ion. Activation of ammonium ferrierite for conversion of branched paraffins is accomplished (1) by treatment with HF or (2) by heating in steam at a temperature within the above range, followed by exchange with ammonium ion. Ferrierite ore per se may be treated with HF, but to complete activation for conversion of branched paraffins, the HF treated ore must be exchanged with the ammonium ion.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
A process for the catalytic conversion of a hydrocarbon charge comprising normal paraffins and isoparaffins, both having from 4 to 20 carbon atoms, which comprises contacting same under hydrocarbon conversion conditions with a catalyst comprising a ferrierite activated by steps comprising a first contact of said ferrierite with the ammonium ion or aqueous HF and a second contact wherein the ammonium ion-treated ferrierite is contacted with aqueous HF and the aqueous HF-treated ferrierite is contacted with the ammonium ion.
Claim 2
Dependent Claim
79 words
A process for the catalytic conversion of a hydrocarbon charge comprising normal paraffins and isoparaffins, both having from 4 to 20 carbon atoms, which comprises contacting same under hydrocarbon conversion conditions with a catalyst comprising a ferrierite activated by steps comprising a first contact of said ferrierite with the ammonium ion or aqueous HF and a second contact wherein the ammonium ion-treated ferrierite is contacted with aqueous HF and the aqueous HF-treated ferrierite is contacted with the ammonium ion.
Claim 3
Dependent Claim
15 words
The process of claim 1 wherein the said catalyst is selective toward cracking normal paraffins.
Claim 4
Dependent Claim
19 words
The process of claim 1 wherein the α value of the said catalyst is substantially in excess of 200.
Claim 5
Dependent Claim
20 words
The process of claim 1 wherein the said catalyst is selective toward cracking normal paraffins and controlled amounts of isoparaffins.
Claim 6
Dependent Claim
15 words
The process of claim 1 wherein the ferrierite is first contacted with the ammonium ion.
Claim 7
Dependent Claim
14 words
The process of claim 1 wherein the ferrierite is first contacted with aqueous HF.
Claim 8
Dependent Claim
10 words
The process of claim 1 wherein the hydrocarbon is 2,3-dimethylbutane.
Claim 9
Dependent Claim
10 words
The process of claim 1 wherein the hydrocarbon is 3-methylpentane.
