As the bubbles rise, mass transfer of the reactant gases takes place as they flow (diffuse) in and out of the bubble to contact the solid particles where the reaction product is. The pyrolysis of biomass starts in the bed reactor thanks to the high thermal exchange with the oxidant agent. Consequently, this study is aimed at proposing a methodology.
