Modeling Pyrolysis of Cotton Fabric Wastes Used for Renewable Energy Source

A computational model of pyrolysis of cotton fabric wastes used for bio-energy source is presented. The model describes thermal and oxidative degradation of cotton fabric under the oxygen-containing atmosphere and considers pseudo bi-component separate-stage kinetic process. Both exothermic and endothermic reactions are included in the decomposition process. At present, gas phase oxidation reactions are not included. Comparison with experimental results demonstrates that the predictions of the mass loss rate and temperature profile with these cotton fabrics are in agreement with the experiment. Effects of thermal radiation and ambient oxygen concentration on decomposition have also been investigated.
