Abstract：By using coking coal from Shougang coking plant, experimental study on coking with preliminary disposed coal was done. The main point of preliminary disposing was to increase the bulk density of coal and reduce the percentage of moisture in coking coal obviously. The result shows that the qualities of coke were improved generally if coking experiment was done with preliminary disposed coal in which the percentage of weakly caking coal increases to 45%. With preliminary disposed coal, throughput of coking is improved obviously, output of water is reduced obviously, and the time for coking is reduced. As the by products of coking with preliminary disposed coal were investigated, percentage of aromatic compounds in tar is increased, percentage of H2 in gas is increased, and the percentage of CH4 in gas is decreased.
