Reaction kinetics of paddy husk thermal decomposition

The physical characteristics, proximate analysis, elemental analysis and ch emical analysis of paddy husk, an important renewable source of energy, are reported in this paper. The kinetic parameters far the thermal degradation of paddy husk at heating rates of 10 and 100 degrees C min(-1) and under a tmospheres of air and oxygen-nitrogen mixture (5:95) have been evaluated fr om experimentally obtained TGA data. The limitations of the existing TGA mo dels are discussed, and a modified model has been used for correlation of t he data.
