ABSTRACT:
Low rank coals such as subbituminous or lignites containing more than about 10 wt. % moisture are first dried and then passed to a fluidized bed where the coal is passivated against reabsorption of moisture by coating the warm coal particles with a heavy liquid hydrocarbon material. Such coating substantially prevents the reabsorption of moisture in the coal, and thereby prevents autogenous heating and possible spontaneous ignition during subsequent transportation or storage of the passivated coal.
