A PROCESS FOR STABILIZING LIGNITIC AND SUB-BITUMINOUS COAL AGAINST SPONTANEOUS COMBUSTION

摘要

A process for stabilizing lignitic and sub-bituminous coal against spontaneous combustion which comprises mixing as-mined lignitic or sub- bituminous coal with said hot, completely or partially dried lignitic or sub-bituminous coal in an amount to produce a weight ratio of dried coal to as-mined coal of from about 1:2 to about 10:1.
