Abstract

An olefin oligomerization process comprises contacting an olefin feed with a catalyst composition. The catalyst composition includes a crystalline aluminosilicate having FAU, EMT or a combination of FAU and EMT framework type. The crystalline aluminosilicate has cobalt and at least one alkaline earth metal selected from calcium, barium, strontium and mixtures thereof within its intra-crystalline cages.

First claim

The invention claimed is:

1. An olefin oligomerization process comprising contacting an olefin feed with a catalyst composition under conditions suitable for oligomerization, wherein the catalyst composition comprises a crystalline aluminosilicate having the FAU, the EMT or a combination of FAU and EMT framework types, said crystalline aluminosilicate having cobalt and at least one alkaline earth metal selected from calcium, barium, strontium and mixtures thereof within its intra-crystalline cages.

2. The olefin oligomerization process of claim 1 , wherein the crystalline aluminosilicate has a composition according to formula (I):
Co x M1 y M2 z Al p Si 192-p O 384   (I)

in which:
p is the number of aluminium atoms per mol of aluminosilicate, and p is at least 40, but is not greater than 96;
x is the number of Co atoms per mol of aluminosilicate and x is at least 4, but is not greater than (p/2)−5;
M1 is calcium, barium, strontium or a mixture thereof;
y is the number of M1 atoms per mol of aluminosilicate, and y is at least 5, but is not greater than (p/2)−x;
M2 is sodium, potassium or a mixture thereof;
z is number of M2 atoms per mol of aluminosilicate, and z≧0 with z=p−2x−2y.

3. The olefin oligomerization process of claim 2 , wherein p is at least 50, but is not greater than 76, x is at least 4 and is not greater than 10, y is at least 10 and is not greater than 16 and z>0 and z=p−2x−2y.

4. The olefin oligomerization process of claim 2 , wherein M1 is calcium.

5. The olefin oligomerization process of claim 2 , wherein M2 is sodium.

6. The olefin oligomerization process of claim 1 , wherein the crystalline aluminosilicate has the FAU framework type.

7. The olefin oligomerization process of claim 6 , wherein the crystalline aluminosilicate is zeolite Y.

8. The olefin oligomerization process of claim 2 , wherein the olefin feed comprises C3 to C6 olefins.

9. The olefin oligomerization process of claim 8 , wherein the olefin feed comprises butene.

10. A crystalline aluminosilicate of the FAU, the EMT or a combination of the FAU and EMT framework types, having a composition according to formula (I):
Co x M1 y M2 z Al p Si 192-p O 384   (I)

wherein:
p is the number of aluminium atoms per mol of aluminosilicate, and p is at least 50, but is not greater than 76;
x is the number of Co atoms per mol of aluminosilicate and x is at least 4 and is not greater than 10;
M1 is calcium, barium, strontium or a mixture thereof;
y is the number of M1 atoms per mol of aluminosilicate, and y is at least 10, but is not greater than 16;
M2 is sodium, potassium or a mixture thereof;
z is the number of M2 atoms per mol of aluminosilicate, and z>0 with z=p−2x−2y.

11. The crystalline aluminosilicate of claim 10 , wherein M1 is calcium.

12. The crystalline aluminosilicate of claim 11 , wherein M2 is sodium.

13. The crystalline aluminosilicate of claim 10 , wherein the crystalline aluminosilicate has the FAU framework type.

14. The crystalline aluminosilicate of claim 13 , wherein the crystalline aluminosilicate is zeolite Y.
