PROCESS FOR OBTAINING WAX FRACTIONS FROM A FEED WAX
A process for obtaining a wax fraction from a feed wax, the process comprising: (a) providing a molten feed wax in a container; (b) solidifying the feed wax by cooling; (c) increasing the temperature of the feed wax to a temperature at which a first fraction of the feed wax melts, said first fraction having a congealing point which is lower than the congealing point of the feed wax; (d) recovering the first fraction of the feed wax; (e) increasing the temperature of the remaining feed wax to a temperature at which a further fraction of the feed wax melts; and (f) recovering the further fraction of the feed wax. The feed wax comprises at least 75 wt.-% of linear alkanes and each recovered fraction comprises at least 19 wt.-% of the feed wax.

Hydro-Dealkylation Process To Generate High Quality Fuels, Base Stocks And Waxes
Provided are methods of hydro-dealkylation of hydrocarbon feedstock to produce an intermediate hydrocarbon product having a boiling point at T10 of greater than about 500 F.+ by distillation method ASTM D7169 and a viscosity index greater than about 120 in accordance with ASTM D2270 where at least about 50 percent of the hydrocarbon feedstock is a SIMDIS of 400 F. The intermediate hydrocarbon product can be used to produce a base stock, a wax and/or paraffinic diesel.

Deoiling process
The present disclosure generally relates to methods for deoiling a hydrocarbon feed and to products formed therefrom. In an embodiment is provided a method of deoiling a feed that includes introducing a waxy feed and a deoiling solvent to a dilution chilling zone; mixing the waxy feed and the deoiling solvent in the dilution chilling zone at a temperature of from about 10 F. to about 30 F. to form a slurry; introducing the slurry to a filter zone, the filter zone comprising one or more filter stages, wherein a temperature of the slurry is from about 40 F. to about 75 F.; separating the wax from the oil and the deoiling solvent to form a wax cake in a first filter stage; and washing the wax cake in the first filter stage with the deoiling solvent to obtain a composition comprising a wax. In another embodiment is provided a composition comprising a wax.
