Abstract
786,207. Coking. GREAT LAKES CARBON CORPORATION. Dec. 9, 1955 [April 18, 1955], No. 35486/55. Class 55 (1). Carbonaceous material, suitable as a filter aid, is produced by heat treatment of a bituminous material which is solid at ordinary temperatures and expands and becomes plastic on heating. The bituminous material is finely ground and is first subjected to a flash-calcination in an atmosphere containing oxygen in such amount that at least 10 per cent of the evolved combustible volatiles remain unburned. The solids are then separated from the gaseous and vaporous products at a temperature not less than that required to maintain substantially all the vaporous products in the vapour state, and, finally, the solids are heated to remove residual volatile matter remaining on the surfaces of the particles. Pulverulent bituminous coal is fed into a pressurized hopper 12 having a rotary agitator 13 and a feed screw 14 which delivers the coal to an entraining airstream for delivery to the top of the flash-calcination chamber 15. By " flash-calcination " is meant a very rapid upheat rate, i.e. in excess of 2000‹ F. at the surfaces of the particles, in a chamber, i.e. the chamber 15, maintained at a temperature sufficient to ignite the particles. A temperature in excess of 1150‹ F., and preferably between 1350‹ and 1650‹ F., is mentioned. A blower 24 supplies air through valves 27, 28. The gaseous and vaporous products are conveyed from the chamber 15 to the cyclone 16, the separated gases and vapours passing to a combustion chamber 26 supplied with air by a blower 25. The solids for the cyclone 16, which is maintained under pressure by a valve 30, are entrained in air from the blower 24 and passed to a chamber 17 supplied with secondary air at 33 to maintain the temperature at 1300-2300‹ F. The products are passed through a cyclone 18, the separated gases being scrubbed at 19. A blower 22 maintains a negative pressure in the chamber 17, and sludge from the scrubber is collected at 20. The final filter aid material is passed through a valve 34 into a drum 21. The plant is brought initially to operating temperatures by. auxiliary burners in the chambers 15, 17 supplied with fuel gas by a blower 23.
