Abstract

A single particle model able to predict the evolution of the product yields during biomass fast pyrolysis is developed. Mass balance equations based on a kinetic scheme of solid-phase pyrolysis are coupled to heat-transfer equations. This two-dimensional model is solved by the finite volume method. The model results are compared to experimental data obtained in an image furnace, where biomass pellets are submitted to a controlled and concentrated radiation. Heat flux densities that are available at the biomass surface are similar to those encountered in fluidized beds (0.2-0.8 x 106 W m-2). The comparison between the experimental data and simulated results shows that the kinetic parameters need to be further optimized to accurately represent the final product yields.
