Abstract
Official abstract text for this publication.
Provided is an improved process for olefin oligomerization allowing one to realize superior selectivity. The process comprises contacting a hydrocarbon feed comprised of straight and branched chain olefins under oligomerization conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing for elimination of mass transfer in comparison with regular SSZ-70. The result is superior selectivity.
First claim
Opening claim text (preview).
What is claimed is: 1. An oligomerization process comprising reacting an olefin feed comprising at least one olefin having from 2 to 21 carbon atoms under oligomerization conditions with a catalyst comprising delaminated SSZ-70 having a layer with a single unit cell of thickness in one dimension. 2. The process of claim 1 , wherein the olefin feed comprises straight and branched chain olefins. 3. The process of claim 1 , wherein the olefin feed comprises ethylene. 4. The process of claim 1 , wherein the oligomerization conditions include a temperature in a range of from 0° C. to 500° C. 5. The process of claim 1 , wherein the catalyst further comprises at least one transition metal. 6. The process of claim 5 , wherein the catalyst comprises at least one Group VIII metal. 7. The process of claim 1 , wherein the delaminated SSZ-70 is a delaminated Al-SSZ-70 material. 8. The process of claim 1 , wherein the delaminated SSZ-70 is a delaminated B-SSZ-70 material. 9. The process of claim 1 , wherein a product comprising a mixture of alpha-olefins containing from 4 to 54 carbon atoms is recovered. 10. The process of claim 1 , wherein the reaction is conducted in the liquid phase.
