ABSTRACT:
Upgrading of Fischer-Tropsch synthesis product is accomplished by water washing the product effluent to separate oxygenates therefrom, separating the washed effluent to recover a C.sub.3 -C.sub.4 rich fraction, a C.sub.5 plus gasoline fraction, a light fuel oil fraction and a heavy fuel oil fraction which is subjected to hydrodewaxing conditions to produce additional light fuel oil and gasoline boiling product. The light fuel oil products were hydrotreated and the synthesis gasoline is octane improved with ZSM5 crystalline zeolite.
