Temperature dependence of reaction rate in the oxidation of Dafosi coal

摘要：

　　Adiabatic self-heating tests had been conducted on Dafosi coal.Analysis of the relationship of temperature and reaction rate revealed that the dependence of coal sample temperature on reaction rate can be described by a third order polynomial from 40℃ up to 155℃.But at a small interval of temperature, the reaction rate still conforms to the Arrhenius kinetic model.When Arrhenius equation is used to solve the kinetic parameters of the coal spontaneous combustion, the coal temperature should be processed in segment.
