摘要:
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.
