Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are produced from non-shifting Fischer-Tropsch processes by separating the Fischer-Tropsch product into a lighter and heavier fractions, e.g., at about 700° F., subjecting the 700° F.+ fraction to

Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are produced from non-shifting Fischer-Tropsch processes by separating the Fischer-Tropsch product into a lighter and heavier fractions, e.g., at about 700° F., subjecting the 700° F.+ fraction to hydro-treating, and combining the 700° F.- portion of the hydrotreated product with the lighter fraction that has not been hydrotreated.

1. A process for producing a distillate fuel heavier than gasoline comprising: (a) separating the product of a Fischer-Tropsch process into a heavier fraction and a lighter fraction; (b) hydroisomerizing the heavier fraction at hydroisomerization conditions and recovering a 700° F.- fraction therefrom; and (c) blending at least a portion of the recovered fraction of step (b) with at least a portion of the lighter fraction. 2. The process of claim 1 wherein a product boiling in the range 250-700° F. is recovered from the blended product of step (c). 3. The process of claim 2 wherein the recovered product of step (c) contains 0.001-0.3 wt % oxygen, water free basis. 4. The product of claim 3. 5. The process of claim 2 wherein the lighter fraction is characterized by the absence of hydrotreating. 6. The process of claim 2 wherein the lighter fraction contains C12+ primary alcohols. 7. The process of claim 6 wherein the lighter fraction contains essentially all of the C12-C24primary alcohols. 8. The process of claim 2 wherein the Fischer-Tropsch process is characterized by non-shifting conditions.
