Abstract

Medium-density fiberboard (MDF) and particle board (PB) showed similar pyrolysis characteristics. Thermogravimetric analysis displayed the main weight loss between 200 and 400 °C, continued up to 600 °C. The activation energy (E_a) values at each conversion were in the range of 166–372 kJ/mol for MDF and 161–325 kJ/mol for PB and indicated independent reactions of hemicellulose, cellulose, lignin and char stabilization. Isothermal pyrolysis produced hemicellulose pyrolyzates at 300 °C. The main products at 400 °C had similar distribution between MDF and PB. At 600 °C, gas products were increased due to the secondary cracking of pyrolyzates.
