Abstract: A process to prepare paraffins and waxes is provided, the process comprising:subjecting a Fischer-Tropsch product stream comprising paraffins having from 10 to 300 carbon atoms to a hydrogenation step, thereby obtaining a hydrogenated Fischer-Tropsch product stream comprising 10 to 300 carbon atoms;separating the hydrogenated Fischer-Tropsch product stream, thereby obtaining at least a fraction comprising 10 to 17 carbon atoms and a fraction comprising 18 to 300 carbon atoms;separating the fraction comprising 18 to 300 carbon atoms, thereby obtaining one or more first light waxes having a congealing point in the range of 30 to 75° C. and a second heavy wax having a congealing point in the range of 75 to 120° C.; andhydrofinishing one or more wax fractions having a congealing point in the range of 30 to 75° C. thereby obtaining one or more hydrofinished wax fractions having a congealing point in the range of 30 to 75° C.

Abstract: A process for production of middle distillate fraction from gas-to-liquid (GTL) conversion comprising providing a feed stream comprising natural gas and separating a condensate from the feed stream to produce a condensate stream and a feed stream; processing the feed stream via a Fischer-Tropsch (FT) reaction to generate a long chain hydrocarbon product stream; processing the product stream via a heavy paraffinic conversion in order to produce a FT product stream; treating the condensate stream with a desulfurization step to generate a condensate product stream; combining the FT product stream with the condensate product stream to provide a distillate feed stream; and performing a distillation step on the distillation feed stream, wherein the processing steps occur substantially concurrently with the treating step and wherein distillation provides for isolation of middle distillate products. Middle distillate fractions and fuel oils/fuel oil blends obtained according to the process are also provided.
