Evaluation of Current Process Technology in Coal …

Agglomeration of the coal during carbonization can be prevented by a variety of methods; the most attractive one appears to be the bed recirculation method. Finally, desulfurization of the liquid and char products can be achieved by additional treatment with hydrogen but in the case of the char, beneficiation of the feed coal will probably be necessary.
