Kinetic study of orange peel pirólisis
The kinetic study of orange peel pirólisis is realized in this paper. The pirólisis is a complex process because it involves simultaneous chemical reactions, thence the difficulty to realize a kinetic study of the material. We use several equations: Coats (integral), Sharp, Achar (differentials) and isoconversional (free kinetic). The discussion integrated of the kinetic results obtains a larger representability of the same, which results necessary in the treatment of natural materials. The study kinetic is determined for models D4 and F1. The rank of activation energy are 80-90 kJ/mol (free kinetic) and 25-237 kJ/mol (model fitting method) because simultaneous reactions occur and demonstrates the biggest precision of the isoconversional method.
Keywords: heterogeneous hinetic, pirólisis, orange peel.
