Abstract
The use of high silica to alumina ratio large pore zeolites, in combination with a hydrogenation/dehydrogenation component, to convert Fischer-Tropsch heavy end products which may contain paraffins, olefins and oxygenates into low pour point distillates with high cetane number and extra high VI lube is described. The lube can be dewaxed by a conventional solvent process, by a catalytic process, or by increasing the severity of the hydroisomerization step.
