Kinetic modelling of the pyrolysis of biomass and biomass components
TLDR
In this article, the kinetics of pyrolysis of lignocellulosic materials were studied with a view of providing simple kinetic models for engineering purposes, based on the results obtained by means of thermal analysis techniques.Abstract:
The kinetics of the pyrolysis of lignocellulosic materials was studied with a view of providing simple kinetic models for engineering purposes. Experimental data obtained by means of thermal analysis techniques suggest that the pyrolysis of fine particles (below 1 mm) can be considered to be controlled by pyrolysis kinetics. The rate of pyrolysis of one biomass type can be represented by the sum of the corresponding rates of the main biomass components (cellulose, lignin, hemicellulose). The kinetics of each of these components was simulated by a kinetic scheme capable of predicting the pyrolysis rate and the final weight-loss for a wide range of pyrolysis parameters including various heating conditions.read more
