Abstract

Process for treating coal by feeding a first batch of raw coal to a first dryer to remove moisture contained in the raw coal to produce demoisturized coal; feeding the demoisturized coal to a devolatilizer to remove volatile material from the demoisturized coal to produce devolatilized coal; feeding a first portion of the devolatilized coal to a combustor to provide heat for the process; feeding a second portion of the devolatilized coal to a coater; feeding a second batch of raw coal to a slave dryer to produce a second batch of demoisturized coal; feeding the second batch of demoisturized coal to the coater where the second portion of devolatilized coal and the second batch of demoisturized coal are coated with volatile material produced in the devolatilizer, to produce a stabilized coal product; and collecting the stabilized coal product.
