Kinetic study for the thermal decomposition of cellulose and pine sawdust in an air atmosphere

摘要

Isothermal and dynamic experiments have been performed to obtain kinetic equations for the thermal decomposition of lignocellulosic materials in an air atmosphere. The experiments were performed with cellulose, which is considered to be the main component in these materials, and pine sawdust. Equations corresponding to the different ranges of temperature and solid conversions have been obtained. A comparison has been carried out between the kinetic constant values obtained with cellulose and pine sawdust under the same operating conditions.
