Abstract

A diesel engine fuel is produced from Fischer-Tropsch wax by separating a light density fraction, e.g., C.sub.5 -C.sub.15, preferably C.sub.7 -C.sub.14 cut having at least 80+ wt % n-paraffins, no more than 5000 ppm alcohols as oxygen, less than 10 wt % olefins, twice aromatics and very low sulfur and nitrogen.
