I was referring to the patent language in the referenced patent which indicated it was a GTL process:
" In an F-T synthesis process, a synthesis gas comprising a mixture of H2 and CO is catalytically converted into hydrocarbons, usually waxy hydrocarbons (referred to as F-T wax) that are generally converted to lower boiling material by process comprising hydroisomerisation and optionally dewaxing. These proces are well known by the person of ordinary skill in the art.
 The process of making a lubricant base oil from an F-T wax may include preliminary treatment(s). Treatment to remove any sulfur and nitrogen compounds is not normally needed because F-T waxes have only trace amounts of sulfur or nitrogen. However, F-T waxes may benefit from prehydrotreatment to remove oxygenates.
 Particularly favorable processes that can be used for the production of the FT Group III oil are described in U.S. Pat. Nos. 4,594,172; 4,943,672; 6,046,940; 6,475,960; 6,103,099; 6,332,974; and 6,375,830.
 F-T base stocks have a beneficial kinematic viscosity advantage over conventional Group II and Group III base stocks and base oils. Such F-T base stocks and base oils can have significantly higher kinematic viscosities, up to about 20-50 mm /s at 1000C, whereas by comparison commercial Group II base oils can have kinematic viscosities, up to about 15 mm /s at 1000C, and commercial Group III base oils can have kinematic viscosities, up to about 10 mm /s at 1000C. The higher kinematic viscosity range of F-T base stocks and base oils, compared to the more limited kinematic viscosity range of Group II and Group III base stocks and base oils, in combination with the instant invention can provide additional beneficial advantages in formulating lubricant compositions.
 The F-T Group III oils used in the present invention are characterized as having predominantly paraffinic components and are further characterized as having high saturates levels, low-to-nil sulfur, low-to-nil nitrogen, low-to-nil aromatics, and are essentially water-white in color. The preferred F-T base oils have less than 0.1 wt% aromatic hydrocarbons, less than 20 wppm nitrogen containing compounds, and less than 20 wppm sulfur containing compounds, The FT oils more often have a nominal boiling point of 3700C+..."
