Process for gasifying carbonaceous solids

Claim 1

IN A PROCESS FOR THE PRODUCTION OF CARBON MONOXIDE AND HYDROGEN BY REACTION OF A SOLID CARBONACEOUS FUEL WITH STREAM AND SUBSTANTIALLY PURE OXYGEN WITHIN A CLOSED REACTION ZONE MAINTAINED AT AN ELEVATED PRESSURE, THE IMPROVEMENT WHICH COMPRISES PASSING AS A CONTINUOUS STREAM IN TURBULENT FLOW THROUGH A TUBULAR HEATING ZONE WITHIN SAID REACTION ZONE AT A PRESSURE IN EXCESS OF THE PRESSURE IN SAID REACTION ZONE A SUSPENSION OF PARTICLES OF SAID FUEL IN A LIQUID WHICH IS SUBSTANTIALLY INERT WITH RESPECT TO REACTION WITH SAID FUEL UNDER THE CONDITIONS EXISTING IN SAID HEATING ZONE, VAPORIZING SAID LIQUID WITHIN SAID HEATING ZONE BY HEAT EXCHANGE WITH SAID REACTION THEREBY FORMING A DISPERSION OF PARTICLES OF SAID FUEL IN VAPOR WITHIN SAID HEATING ZONE AND REMOVING HEAT FROM SAID REACTION ZONE, AND CONTINUOUSLY INTRODUCING RESULTING DISPERSION OF SOLID CARBONACEOUS FUEL IN VAPOR INTO SAID GASIFICATION ZONE AS REACTANT FOR THE PRODUCTION OF CARBON MONOXIDE AND HYDROGEN.
