Kinetic modelling of the pyrolysis of Miscanthus × Giganteus from the thermogravimetric analysis of its fractionated components

In this paper the thermal behaviour of Miscanthus × Giganteus (M×G) is studied by thermogravimetric analysis. In order to characterise the thermal behaviour of its cellulose, hemicellulose and lignin, the raw M×G material was treated sequentially by water, H₂SO₄ and KOH. The global kinetic parameters for each component were determined by subsequent modelling of the TG data with the Ozawa-Flynn-Wall method and multivariate non-linear regression. It is found that the global pyrolysis of M×G can be satisfactorily described using a six steps-kinetic scheme. The analytical method proposed here can be probably extended without too many efforts to other biomass products. An erratum to this article can be found at
