说明书摘要	Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are directly produced from synthesis gas over activated carbon supported cobalt based Fischer-Tropsch catalyst under the condition of temperature within the range of 120 to 400 C., reaction pressure within the range of 0.5 to 10.0 MPa, volume hourly space velocity of a mixture of hydrogen and carbon monoxide within the range of 100 to 5000, the mole ratio of hydrogen to carbon monoxide within the range of 1 to 4. 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.
