Abstract
The kinetics of the thermal decomposition of Huadian oil shale was studied at five different isothermal atmospheres of 623K, 648K, 673K, 698K, and 723K. The temperature recorded was that of the sample that the temperature error between furnace and sample will eliminate. According to conversion data, the effect of increased temperature is to decrease the pyrolysis time. The conversion data described the oil shale pyrolysis as two stages, rapid conversion and modest conversion. The Arrhenius equations of ki=1.40×105e-109828/RT and kii=1.76×106e-130463/RT were obtain by isothermal kinetics model for each stage.
