Abstract: Coal fines developed from the processing of coal through a preheating system are accumulated in a secondary cyclone system. The coal fines, at an elevated temperature, are mixed with a hydrocarbon organic binder and compressed into larger particles of sufficient structural integrity and mass to be fed directly through pneumatic pressure coke oven coal charging lines without significant size reduction, resulting in the elimination of fine coal build-up in one coke oven standpipes and charging mains as well as overloading of the charging liquor system.

Abstract: An improved method of rapid liquid quenching of coke wherein hot coke is distributed on a surface, preferably an inclined surface, and a substantially uniform stream of quench liquid is flowed through said hot coke at spaced apart locations so that the quench liquid penetrates the depth of the bed prior to complete vaporization and percolates through the bed quenching coke as it goes. Particularly good results are obtained by oscillating the stream or streams slowly over the coke.
