METHOD FOR PASSIVATING PARTICULATE COAL Abstract A method is disclosed for drying and passivating wet coals, for example bituminous, subbituminous or lignite. The wet coal is preheated with hot dry gas in an initial heating zone, then is contacted with a heavy hydrocarbonaceous treatment material having a softening point at least 60°C. The coated particles are further heated to a temperature of at least 200°C but below the coal decomposition temperature for a time of about 0.5 to 20 minutes, and cooled.
