Abstract
A process for producing additive compositions, especially via a Fischer-Tropsch reaction, useful for improving the cetane number or lubricity, or both the cetane number and lubricity, of a mid-distillate, diesel fuel. In producing the additive, the product of a Fischer-Tropsch reaction is separated into a high boiling fraction and a low boiling, e.g., a 700.degree. F.- fraction. The high boiling fraction is hydroisomerized at conditions sufficient to convert it to a 700.degree. F.- low boiling fraction, the latter being blended with the 700.degree. F.- fraction and the diesel additive is recovered therefrom.
