Abstract: Cement-forming raw materials are introduced into a swirling stream of hot gas in a cylindrical reaction zone where the raw materials react to form clinkers and where the gas stream holds the clinker particles in suspension until the particles grow heavy enough to drop to the lower portion of the reaction zone. Apparatus suitable for carrying out the process is also described.

Abstract: A PROCESS FOR MANUFACTURING CARBON BLACK WHICH CONSISTS OF INJECTING A HYDROGEN FEED MATERIAL INTO A STREAM OF VERY HOT, HIGH VELOCITY COMBUSTED GASES. THE VELOCITY MUST BE GREATER THAN 1,000 FEET PER SECOND, AND THE TEMPERATURE 4,000*F.-6,000*F. THE COMBUSTED GASES ARE OBTAINED BY BURNING FUEL WITH PURE OXYGEN OR OXYGEN ENRICHED AIR. THE PROCESS MAKES IT POSSIBLE TO OBTAIN CHANNEL GRADE CARBON BLACK BY MEANS OF A FURNACE PROCESS.

Abstract: A BURNER SUITABLE FOR THE MANUFACTURE OF CARBON BLACK COMPRISES AN INTERNAL COMBUSTION CHAMBER COMMUNICATING AXIALLY AT ITS DISCHARGE END WITH A PROCESSING CHAMBER. THE BURNER OPERATES BY HAVING FLUID HYDROCARBON STOCK INJECTED AXIALLY AS A CONTINOUS COHERENT STREAM FROM THE INLET END OF THE COMBUSTION CHAMBER THROUGH SUCH CHAMBER AND INTO THE PROCESSING CHAMBER WHERE A CONSTRICTED, HIGH VELOCITY STREAM OF HOT COMBUSTION PRODUCTS DISPERSE, SHEAR AND PYROLYZE THE HYDROCARBON FEED STOCK TO FORM CARBON BLACK. USE OF A WATER-COOLED, HEAT CONDUCTIVE METAL BODY WHICH FORMS THE WALLS OF BOTH THE COMBUSTION AND PROCESSING CHAMBERS PERMITS USE OF VERY HIGH OPERATING TEMPERATURES.
