Study of kinetic parameters of thermal decomposition of bagasse and sugarcane straw using Friedman and Ozawa–Flynn–Wall isoconversional methods

摘要: Pyrolysis process of sugarcane bagasse and straw was studied with the objective determining kinetic parameters activation energy (E), logarithm pre-exponential factor (log A) in agreement converted fraction (α). The determination done through software thermokinetics by NETZSCH, which associated “Model Free” package enabled these Friedman Ozawa–Flynn–Wall isoconversion models a probable mechanism that describes thermal decomposition materials. degradation carried out range 303–1073 K under nitrogen flow heating rate used 5, 10, 15, 20 K min−1. obtained results showed most appropriate model to describe autocatalytic reactions three parallel stages (F n C n model) for also two parallels model).
