Abstract [en]

To study biomass pyrolysis process, a mathematic model is developed in this work focusing on the cellulose constituent. A single cellulose particle is supposed to experience pyrolysis once exposed to an environment of 800 C°. The model involves the pyrolytic kinetic scheme and the detailed heat and mass transfers caused by radiation, conduction, diffusion and convection with respect to the solid, liquid and gas products from pyrolysis. Based on the model computation results, the heat and mass transfer limits to the pyrolysis are discussed. The central role of the pyrolytic reaction heat versus a slow heat supply through the particle is identified. Various predictions by the model provide a good understanding of the complex process of biomass pyrolysis, which can be useful for applications of thermochemical conversions of biomass.
