Abstract

A process for drying and passivating coal that contains from about 10 to about 40 weight percent moisture. The coal is passed through a fluidized bed and is contacted with a fluidizing gas that contains oxygen at temperatures of about 575 to about 620 degrees Fahrenheit. The dried coal is then rapidly cooled to about 200 to about 300 degrees Fahrenheit in less than about 120 seconds. It is then cooled further to less than about 100 degrees Fahrenheit in less than about 60 minutes.
