Abstract:
1. A method of producing transportation fuel, comprising: providing a highly paraffinic formation fluid produced from a subsurface in situ heat treatment process to a gas/liquid separator, wherein a majority of the highly paraffinic formation fluid comprises highly paraffinic hydrocarbons having a boiling point distribution between −5° C. and about 350° C.; in the gas/liquid separator, separating from the highly paraffinic formation fluid a highly paraffinic hydrocarbon stream, wherein the separated highly paraffinic hydrocarbon stream has a boiling range distribution between about 50° C. and about 350° C., a total paraffinic content of at least 70% by weight, and a sulfur content of at least 0.01% by weight; hydrotreating the separated highly paraffinic hydrocarbon stream to produce a hydrotreated highly paraffinic, low sulfur, hydrocarbon stream having a boiling range distribution between about 50° C. and about 350° C., a total paraffinic content of at least 70% by weight, a sulfur content less than the sulfur content of the separated highly paraffinic hydrocarbon stream, and a wear scar diameter of no greater than 0.9 mm; distilling the highly paraffinic, low sulfur, hydrocarbon stream to produce a distilled highly paraffinic, low sulfur, hydrocarbon stream having a boiling range distribution between 150° C. and 350° C., a total paraffinic content of at least 70% by weight and a wear scar diameter of no greater than 0.9 mm; and providing one or more additives to the distilled highly paraffinic, low sulfur, hydrocarbon stream having a boiling range distribution between 150° C. and 350° C., a total paraffinic content of at least 70% by weight, and a wear scar diameter of no greater than 0.9 mm to produce transportation fuel, wherein boiling range distribution is determined using ASTM Method D5307, total paraffinic content is determined using ASTM Method D6730, sulfur content is determined using ASTM Method D4294, and wear scar diameter is determined using ASTM Method D5001.
