Abstract

Provided is an improved hydroprocessing process allowing one to realize superior isoselectivity. The process comprises contacting a feed comprised of normal hydrocarbons under hydroprocessing conditions with a catalyst comprising delaminated SSZ-70.

First claim

What is claimed is:

1 . A hydroprocessing process comprising contacting a feed having normal hydrocarbons under hydroprocessing conditions with a catalyst comprising delaminated SSZ-70.

2 . The process of claim 1 , wherein the delaminated SSZ-70 is predominantly in the hydrogen form.

3 . The process of claim 1 , wherein the catalyst further comprises at least one metal selected from the group consisting of nickel (Ni), palladium (Pd), platinum (Pt), cobalt (Co), iron (Fe), chromium (Cr), molybdenum (Mo), tungsten (W), and mixtures thereof.

4 . The process of claim 1 , wherein the delaminated SSZ-70 is a delaminated Al-SSZ-70 material.

5 . The process of claim 1 , wherein the delaminated SSZ-70 is a delaminated B-SSZ-70 zeolite.

6 . The process of claim 1 , wherein the feed comprises linear paraffinics, FT-derived hydrocarbons, vacuum gas oil and mixtures thereof.

7 . The process of claim 6 , wherein the hydroprocessing process realizes an isoselectivity of at least 40 wt % for nC 16 conversion.

8 . The process of claim 7 , wherein the hydroprocessing process realizes an isoselectivity of at least 50 wt % for nC 16 conversion.

9 . The process of claim 7 , wherein the yield of isomerized C 16 products from nC 16 hydrocarbons is at least 40 wt %.

10 . The process of claim 1 , wherein the delaminated SSZ-70 is prepared by
preparing a mixture comprising chloride and fluoride anions and an SSZ-70 zeolite; maintaining the mixture at a pH of 12 or less at a temperature in the range of 5-150° C. for a length of time sufficient to effect the desired delamination; and recovering the delaminated SSZ-70 material.

11 . The process of claim 10 , wherein the pH is about 9 or less.

12 . The process of claim 10 , wherein the mixture comprises a mixture of an alkylammonium chloride and an alkylammonium bromide.

13 . The process of claim 12 , wherein the mixture further comprises an alkylammonium bromide.

14 . The process of claim 12 , wherein DMF is used in preparing the mixture.

15 . The process of claim 1 , wherein the hydroprocessing process is a hydrocracking process comprising contacting the feed under hydrocracking conditions with the delaminated SSZ-70 catalyst.

16 . The process of claim 1 , wherein the hydroprocessing process is a hydroisomerization process comprising contacting the feed under hydroisomerization conditions with the delaminated SSZ-70 catalyst.

17 . The process of claim 16 , wherein the delaminated SSZ-70 catalyst comprises a metal from Group VI and a metal from Group VIII.

18 . The process of claim 16 , wherein the delaminated SSZ-70 is a delaminated Al-SSZ-70 material.

19 . The process of claim 16 , wherein the delaminated SSZ-70 is a delaminated B-SSZ-70 material.
