RECOVERY OF UNGASIFIED SOLID FUEL PARTICLES FROM SUSPENSION IN WATER (D)76, 293-F) ABSTRACT A continuous process for the partial oxidation of solid carbonaceous fuels in the presence of H2O to produce a gas comprising CO and H2 with recovery and recycling of uncombusted solid fuel particles to the partial oxidation zone is disclosed. The uncombusted fuel particles entrained in the product gas are trapped in quench water through which the product gas is bubbled. The quench water containing said fuel particles is held in a settling zone for three to thirty minutes in the temperature range of 100°F. and 706°F., and the pressure range of 50 p.s.i.g. and 3500 p.s.i.g., resulting in a concentrated solid fuel particle bearing lower section and a clarified upper section wherein at least a portion of said lower section is returned to the partial oxidation zone.
