Abstract
A process for converting synthol light oil product of Fischer-Tropsch synthesis to heavy distillate comprising the steps of PA1 contacting the light oil at elevated temperature and pressure with acid zeolite conversion catalyst to oligomerize olefins and convert oxygenated hydrocarbons contained in the light oil thereby providing an effluent containing light heavy distillate range hydrocarbon, hydrocarbon vapor and byproduct water; PA1 flashing and separating the effluent to recover a heavy distillate-rich liquid phase and a light hydrocarbon-rich vapor phase containing byproduct water; PA1 condensing the vapor phase to provide a liquid hydrocarbon recycle stream; PA1 removing byproduct water from the recycle stream; PA1 combining the light oil with the pressurized recycle stream as heat sink to prevent excessive reaction temperature during catalytic conversion.
