The study of the kinetics involved in lignocellulosic biomass pyrolysis has received great attention in the last decades and different mathematical models have been derived. In this chapter, a literature review was performed in order to summarize the existing models that use thermogravimetric data to estimate the kinetic parameters, which are important to improve and optimize the process. Additionally, a case study was presented exemplifying the application of kinetic modeling for the residue of one Brazilian species (Brazil nut woody shell). The isoconversional models of Ozawa-Flynn-Wall, modified Coats-Redfern, and Friedman were applied, as well as three and four independent parallel reactions models. The four reactions model presented the best fit between experimental and theoretical data, providing a better representation of the biomass pyrolysis reaction. |
