Influence of Carbonizing Conditions on coke Properties

Abstract

The influence of various factors like stamping, bulk density, rate of heating, grain size etc., of the coal charge on the properties of coke was studied. On stamping the 10 mm micum index tended to decrease while changes in the other physical properties were erratic. Some blends of high volatile weakly coking and low volatile good coking coals gave better coke on stamping. Small addition of oil produced some improvement in the physical properties of the coke due to increases in the bulk density of the charge. And increase in the bulk density caused by the addition of water gave anomalous results
