EXPERIMENTAL COMPARISON OF THE WEIGHT LOSS DYNAMIC DURING PYROLYSIS BETWEEN LONG FLAME COAL AND OIL RICH COAL

open access: yesInternational Journal of Innovative Research in Advanced Engineering, 2022
For the isothermal pyrolysis of oil rich coal, the activation energy E =235.92 KJ/mol, and the pre-exponential factor lnA=32.324. The activation energy of oil rich coal under isothermal pyrolysis condition is larger than that of long flame coal, E =162.15 KJ/mol, which means that the conversion rate of long flame coal is larger than that of the oil ...
