Abstract
Described herein is a process for hydroisomerising a hydrocarbon feed. The process may comprise: combining a hydrocarbon feed and a hydroisomerisation additive to provide a combined feed; and contacting the combined feed with a hydroisomerisation catalyst comprising zeolite SSZ-91, where the hydroisomerisation additive is a substituted or unsubstituted nitrogen heterocycle.

A process for hydroisomerising a hydrocarbon feed, the process comprising:
- combining a hydrocarbon feed and a hydroisomerisation additive to provide a combined feed;
- and
- contacting the combined feed with a hydroisomerisation catalyst,
- wherein the hydroisomerisation additive is a substituted or unsubstituted nitrogen heterocycle, and the hydroisomerisation catalyst comprises zeolite SSZ-91.
A process for increasing the yield of a base oil produced by hydroisomerising a hydrocarbon feed, the process comprising:
- combining a hydrocarbon feed and a hydroisomerisation additive to provide a combined feed;
- and
- contacting the combined feed with a hydroisomerisation catalyst comprising zeolite SSZ-91 to form a base oil product,
- wherein the hydroisomerisation additive is a substituted or unsubstituted nitrogen heterocycle, and
- the yield of the base oil product is improved by at least 1.0 wt. % compared to the process conducted in the absence of the hydroisomerisation additive.
A process for improving the yield of a base oil produced by contacting a hydrocarbon feed and a hydroisomerisation catalyst, the process comprising combining the hydrocarbon feed with a hydroisomerisation additive to form a combined feed before contacting the combined feed and the hydroisomerisation catalyst,
- wherein the hydroisomerisation additive is a substituted or unsubstituted nitrogen heterocycle, and the hydroisomerisation catalyst comprises zeolite SSZ-91.
