Process for producing synthesis gas and coke

Claim 1

A PROCESS FOR PRODUCING SYNTHESIS GASES, COMPRISING, GASIFYING, IN A DUST GASIFIER, A FINELY-DIVIDED SOLID CARBONACEOUS FUEL WITH A CHEMICALLY COMBINED OXYGENCONTAINING FLUID OF THE GROUP CONSISTING OF THE STEAM AND CO2 CAPABLE OF REACTING ENDOTHERMICALLY WITH SAID FINELY-DIVIDED FUEL AND A FREE OXYGEN-CONTAINING GAS OF THE GROUP CONSISTING OF OXYGEN AND OXYGEN ENRICHED AIR, IN PROPORTIONS TO PRODUCE A HOT MIXTURE OF SYNTHESIS GASES, UNREACTED CARBONACEOUS FUEL DUST AND FLUID, FILTERING, SAID HOT MIXTURE THROUGH A FIXED BED OF MOVING SOLID CARBONACEOUS FUEL WHILE FLOWING COCURRENTLY WITH THE FLOW OF SAID MOVING CARBONACEOUS FUEL IN SAID FIXED BED, THE RATE OF FLOW OF SAID MOVING FUEL BEING CONTROLLED, SO THAT ONLY A PORTION, BUT NOT ALL, OF THE TOTAL CARBON CONTAINED THEREIN AND IN SAID UNREACTED FUEL DUST, IS CONSUMED TO PRODUCE SYNTHESIS GASES DURING SAID COCURRENT FLOW OF SAID MOVING FUEL AND SAID MIXTURE, AND SEPARATING SAID GASES FROM THE UNGASIFIED RESIDUE.
