Experimental comparison of the volatile matter loss dynamic during pyrolysis between long flame coal and oil rich coal

For the isothermal pyrolysis of oil rich coal, the activation energy E =182.39 KJ/mol, and the pre-exponential factor lnA=24.12. The activation energy of oil rich coal under isothermal pyrolysis condition is smaller than that of long flame coal, E =239.73 KJ/mol, which means that the conversion rate of long flame coal is smaller than that of the oil rich coal. For the constant heating rate pyrolysis of oil rich coal, the activation energy E =37.338 KJ/mol, and the pre-exponential factor lnA=4.405.
