抄録

The evolution of gaseous O-containing species (CO, CO_2 and H_2O) during carbonization of seven caking coals at a heating rate of 3℃/min has been studied with a quartz-made fixed bed reactor to make clear the influence of oxygen element on coal fluidity. The seven coals provide a Gieseler maximum fluidity (MF) value between 435 and 480℃, and the value depends strongly on the kind coal and ranges from 1.1 to 4.1 log(ddpm). Interestingly, the MF value decreases almost linearly with increasing total amount of (CO plus CO_2 plus H_2O) evolved up to the maximum fluidity temperature described above. Furthermore, the addition of O-containing compounds [phthalide (C_8H_6O_2), 2-naphthoic acid (C_<11>H_8O_2) and fluorescein (C_<20>H_<12>O_5)] to an Australian caking coal lowers the MF value considerably: the value decreases from the original 3.5 to 1.6-2.8 log(ddpm). It is thus probable that some of O-functional groups inherently-present in coal have a negative effect on coal fluidity.
