Abstract
Described herein are processes for hydroisomerising an unconventional feedstock using a hydroisomerisation catalyst comprising zeolite SSZ-91, zeolite SSZ-32, or zeolite SSZ-32x to provide a diesel fuel.
Claims37
A process for hydroisomerising a diesel feedstock, the process comprising contacting a diesel feedstock with a hydroisomerisation catalyst,
- wherein the diesel feedstock comprises or is a biocomponent feed or a Fischer-Tropsch feed, and the hydroisomerisation catalyst comprises zeolite SSZ-91, zeolite SSZ-32 or zeolite SSZ-32x.
A process for upgrading a diesel feedstock, the process comprising:
- contacting a diesel feedstock with a hydroisomerisation catalyst under hydroisomerisation conditions to provide a diesel fuel having a reduced cloud point and a reduced pour point compared to the cloud point and pour point of the diesel feedstock,
- wherein the diesel feedstock comprises or is a biocomponent feed or a Fischer-Tropsch feed, and the hydroisomerisation catalyst comprises zeolite SSZ-91, zeolite SSZ-32 or zeolite SSZ-32x.
A process for providing a diesel fuel exhibiting a lower cloud point and a lower pour point compared to the cloud point and pour point of a diesel feedstock from which the diesel fuel is produced, the process comprising contacting a diesel feedstock and a hydroisomerisation catalyst comprising zeolite SSZ-91, zeolite SSZ-32 or zeolite SSZ-32x under hydroisomerisation conditions to provide a diesel fuel exhibiting a lower cloud point and a lower pour point compared to the cloud point and pour point of a diesel feedstock from which the diesel fuel is produced, wherein the diesel feedstock comprises or is a biocomponent feed or a Fischer-Tropsch feed.
