Abstract
Thermal degradation behavior of rice straw fibers under isothermal heating conditions was studied. The data were modeled by considering the fiber as one pseudo-component using the Málek method. The kinetic model with reaction order n>1 [i.e., RO(n>1)=(1-α)n] described the degradation process of rice straw fiber fairly well in a temperature range up to about 265°C. The kinetic parameters used include activation energy of 116±5kJ/mol, reaction order of 3.0±0.2, and logarithmic value of pre-exponential factor [lnA] of 18.7±0.1lns-1. The model obtained can be used to aid the development of straw fiber-engineering plastic composites. © 2012 The Korean Society of Industrial and Engineering Chemistry.
