Abstract

This study investigated and discussed the drying characteristics of municipal wood wastes (wood, particle board, medium density fiber-board(MDF)) in the $N_2$ environment with an isothermal thermogravimetric analyzer. The drying rate could be expressed by a first order reaction model on remaining fraction of moisture. The activation energy ranged from 12.72 kJ/g mol to 18.31 kJ/g mol and the frequency factor from 0.2155 1/s to 1.249 1/s.
