Diesel fuels containing at least 95 wt % paraffins with an iso to normal ratio of about 0.03 to 0.3, <50 ppm (wt) of sulfur and nitrogen, less than about 2 wt % unsaturates, and about 0.001 to less than 0.3 wt % oxygen were obtained by separating the Fischer-Tropsch product into a lighter (180 to 245 C. fraction) and heavier fractions (245 to 380 C. fraction) utilizing a rough flash, and combining the 180 to 245 C. portion of the lighter product with the 245 to 380 C. fraction in desired ratios. |
