Abstract

757,083. Carbonizing coal. PITTSBURGH CONSOLIDATION COAL CO. May 25, 1954 [June 8, 1953], No. 15754/53. Class 55(1). In a process of carbonizing a coking bituminous coal at a temperature between 800‹ and 1400‹F. the coal is pre-oxidized in particulate form by a gas containing free oxygen under non- agglomerating conditions within the plastic range of the coal, i.e. between 700‹ and 800‹F., and preferably between 750‹-790‹F., until the coal is rendered substantially non-agglomerative when heated to the carbonizing temperature. The process is preferably carried out using the fluidized solids technique but it may be carried out with the coal particles suspended in a gas as a dilute phase. As shown in Fig. 1, coal of fluidizable size is fed from a hopper 10 through line 18 entrained in a stream of recycle gas introduced at 16 into a fluidized preheater 20 which is externally heated and wherein the temperature of the coal is raised to 100‹-650‹F. The preheated solids and-gas overflow into a pipe 22 and pass into a fluidized pre-oxidation zone 26, preheated air being introduced at about 200‹F. into the bottom of the zone. Partial combustion raises the temperature to between 715‹ and 800‹F. and after residence in the zone for between 10-40 minutes the preoxidized coal passes by overflow 28 into a fluidized carbonization zone 32, additional heat being supplied for the carbonization by introducing at 34 hot recycle gas or steam at a temperature of 1200‹-1800‹F. Carbonization is completed at 800‹-1400‹F. in 1-1¢ hours. Coke is withdrawn at 38 and the gases leave by line 42 and pass into a condenser 44 where tar is recovered. In a modification the gases and tar evolved in the pre-oxidation zone may be collected separately from those evolved in the carbonization zone. The preheating of the coal may be carried out by means of hot gases or the preheating may be omitted and any additional heat required in the pre-oxidation zone may be supplied by recycling hot coke from the carbon izing zone or by partial combustion in the preoxidation zone. The heat required for the carbonization may also be supplied by partial combustion or by recycling hot coke from a separate coke combustion zone.
