Abstract
A process for producing a pumpable syncrude from a Fischer-Tropsch wax by fractionating the wax into relatively low boiling fraction containing oxygenate compounds and a relatively high boiling fraction which is substantially free of oxygenate compounds and thereafter isomerizing/hydrocracking the low boiling fraction in the presence of hydrogen and a fluorided Group VIII metal-on-alumina catalyst. The preferred Group VIII metal is platinum. The pumpable syncrude is thereafter fractionated to produce a low boiling fraction which is thereafter isomerized/hydrocracked in the presence of hydrogen and a fluorided Group VIII metal-on-alumina catalyst to produce upgraded middle distillate fuel products. The preferred catalyst for middle distillate production is a fluorided platinum-on-alumina catalyst where a major portion of the fluoride within the catalyst is present as aluminum fluoride hydroxide hydrate.
