1. 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 selected from vegetable oils and animal fats which comprise triglycerides and free fatty acids; or a Fischer-Tropsch feed having a 90% distillation temperature of less than about 750° F. (about 399° C.), and the hydroisomerisation catalyst comprises zeolite SSZ-91.
