    1996-1-1 · It is seen that by adding chemical agents to the coal (up to 25 ) weight loss is decreased as a result of the inhibition of tar production by these chemicals hence enhancing carbon yield. With increasing KOH and ZnCI to coal ratio further from 25 to 75 the weight loss increases and beyond 75 chemical ratio the weight loss is again reduced.
