Abstract:
Process to prepare a haze free base oil having a kinematic viscosity at 100 DEG C of greater than 10 cSt from a Fischer-Tropsch wax feed having a 10 wt% recovery boiling point of above 500 DEG C and a wax content of greater than 50 wt% by performing the following steps, (a) reducing the wax content of the feed to a value of below 50 wt% by contacting the feed with a hydroisomerisation catalyst under hydroisomerisation conditions at a remote location, (b) transporting an intermediate product having a wax content of below 50 wt% as obtained in step (a) from one location to another location, and (c) solvent dewaxing the transported intermediate product to obtain the haze free base oil at the location closer to the end-user.
