Skinner, J L

Dried particulate low rank coal fuel having a reduced reactivity and a reduced dusting tendency is produced from dried particulate low rank coal by a method consisting essentially of: intimately contacting the dried particulate low rank coal with a deactivating oil in an amount sufficient to reduce the reactivity of the dried coal by a desired amount and thereafter intimately contacting the deactivated dried coal with a dedusting oil in an amount sufficient to reduce the dusting tendency of the deactivated dried coal by a desired amount. The deactivating oil has a 5 percent point in excess of about 900/sup 0/ F. and the dedusting oil has a 5 percent point from about 400/sup 0/ F. to about 750/sup 0/ F.
