The evolution of HCN, NH_3 and H_2S during carbonization of seven coking coals has mainly been studied with a flow-type fixed bed quartz reactor to examine the effects of nitrogen and sulfur on coal fluidity. The formation of HCN or NH_3 from these coals starts at about 400℃, and each concentration profile observed provides the main and shoulder peaks around 450 and 670℃, respectively. On the other hand, H_2S evolution occurs mainly around 450 and 550℃. Each coal used also gives a maximum value in fluidity (MF) aroound 450℃. There is an almost linear correlation between MF value and total amount of HCN, NH_3 or H_2S released up to 450℃.
