Abstract
Abstract A shape-selective hydrocracking catalyst prepared by making a composite of a hydrogenation component and a natural ferrierite that has been treated with oxalic acid to impart thereto catalytic activity for converting slightly branched as well as straight chain hydrocarbons. The catalyst is useful for hydrodewaxing and for upgrading naphtha.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
48 words
A catalyst composition comprising natural ferrierite treated by contact with oxalate ion under conditions effective to impart to said ferrierite a Constraint Index from about 1 to 12, and at least one hydrogenation component selected from the metals of Group VIA and Group VIII of the periodic table.
Claim 2
Dependent Claim
48 words
A catalyst composition comprising natural ferrierite treated by contact with oxalate ion under conditions effective to impart to said ferrierite a Constraint Index from about 1 to 12, and at least one hydrogenation component selected from the metals of Group VIA and Group VIII of the periodic table.
Claim 3
Dependent Claim
31 words
The composition described in claim 1 wherein said contacting comprises first contacting said ferrierite with oxalic acid and then contacting the resultant oxalic acid treated-ferrierite with an aqueous diammonium oxalate solution.
Claim 4
Dependent Claim
32 words
The composition described in claim 2 wherein said contacting with oxalic acid is at a temperature between about room temperature and 200° C. for a period of about 1 to 10 days.
Claim 5
Dependent Claim
34 words
The composition described in claim 2 wherein said contacting with aqueous diammonium oxalate solution is at a temperature between about room temperature and 100° C. for a period of about 1 to 10 days.
Claim 6
Dependent Claim
34 words
The composition described in claim 3 wherein said contacting with aqueous diammonium oxalate solution is at a temperature between about room temperature and 100° C. for a period of about 1 to 10 days.
Claim 7
Dependent Claim
19 words
The composition described in claim 1 or 2 or 3 or 4 or 5 wherein said metal comprises platinum.
Claim 8
Independent Claim
58 words
A method for manufacturing a shape-selective hydrocracking catalyst which comprises contacting natural ferrierite with oxalate ion under conditions effective to impart to said ferrierite a Constraint Index from about 1 to 12 and making a composite of said contacted ferrierite with a hydrogenation component selected from the metals of Group VI and Group VIII of the periodic table.
Claim 9
Independent Claim
58 words
A method for manufacturing a shape-selective hydrocracking catalyst which comprises contacting natural ferrierite with oxalate ion under conditions effective to impart to said ferrierite a Constraint Index from about 1 to 12 and making a composite of said contacted ferrierite with a hydrogenation component selected from the metals of Group VI and Group VIII of the periodic table.
Claim 10
Dependent Claim
31 words
The method described in claim 7 wherein said contacting comprises first contacting said ferrierite with oxalic acid and then contacting the resultant oxalic acid treated-ferrierite with an aqueous diammonium oxalate solution.

The method described in claim 7 wherein said contacting with oxalic acid is at a temperature between about room temperature and 200° C. for a period of about 1 to 10 days.
Claim 12
Dependent Claim
34 words
The method described in claim 8 wherein said contacting with aqueous diammonium oxalate solution is at a temperature between about room temperature and 100° C. for a period of about 1 to 10 days.
Claim 13
Dependent Claim
34 words
The method described in claim 9 wherein said contacting with aqueous diammonium oxalate solution is at a temperature between about room temperature and 100° C. for a period of about 1 to 10 days.
Claim 14
Dependent Claim
18 words
The method of claim 7 or 8 or 9 or 10 or 11 wherein said metal comprises platinum.
