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.read more

Isoparaffinic lube basestock compositions
TL;DR: In this paper, a liquid hydrocarbon composition, containing paraffinic hydrocarbon components in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching was defined, was investigated.
Patent
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.
Patent
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.

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.
