TLDR
Fischer-Tropsch wax is converted to a lubricating oil having a high viscosity index and a low pour point by first hydrotreating the wax under relatively severe conditions and thereafter hydroisomerizing the hydrotreated wax in the presence of hydrogen on a particular fluorided Group VIII metal-on-alumina catalyst.
Abstract
Fischer-Tropsch wax is converted to a lubricating oil having a high viscosity index and a low pour point by first hydrotreating the wax under relatively severe conditions and thereafter hydroisomerizing the hydrotreated wax in the presence of hydrogen on a particular fluorided Group VIII metal-on-alumina catalyst. The hydroisomerate is then dewaxed to produce a premium lubricating oil base stock.

Premium synthetic lubricant base stock having at least 95% non-cyclic isoparaffins

TL;DR: In this paper, a premium synthetic lubricating oil base stock having a high VI and low pour point is made by hydroisomerizing a Fischer-Tropsch synthesized waxy, paraffinic feed wax and then dewaxing the hydro isomerate to form a 650-750° F.+ dewwaxate.

Process for the preparation of hydrocarbons

TL;DR: In this article, a process for the preparation of hydrocarbons by catalytic reaction of carbon monoxide with hydrogen is described, in which a feed comprising hydrogen and carbon dioxide is contacted at elevated temperature and pressure with a catalyst comprising cobalt and manganese in which catalyst the cobalt/manganese molar ratio is between 14:1 and 7:1, and the GHSV is at least 1600 N 1/1/h.

Lubricant production process

TL;DR: In this article, a high viscosity index (V.I.) and low pour point are produced by hydroisomerizing a waxy lube feed such as slack wax or a Waxy gas oil over zeolite beta after which aromatic components are removed by extraction, e.g. with furfural.

Process for the hydroisomerization/hydrocracking of fischer-tropsch waxes to produce syncrude and upgraded hydrocarbon products

TL;DR: In this paper, a process for producing a pumpable syncrude from a Fischer-Tropsch wax by fractionating (D-O) the wax into relatively low boiling fraction containing oxygenate compounds and a relatively high boiling fraction which is substantially free of oxygenates compounds and thereafter isomerizing/hydrocracking (R-1) the high boiler fraction in the presence of hydrogen and a fluorided Group VIII metal-on-alumina catalyst.

Process for upgrading wax from Fischer-Tropsch synthesis

TL;DR: In this paper, the waxy liquid phase of an oil suspension of Fischer-Tropsch catalyst containing dissolved wax is separated out and the wax is converted by hydrocracking, dewaxing or by catalytic cracking with a low activity catalyst to provide a highly olefinic product which may be further converted to premium quality gasoline and/or distillate fuel.
