Numerical analysis of a biomass pyrolysis particle model: Solution method optimized for the coupling to reactor models

► Different solution methods of a biomass pyrolysis particle model are compared. ► When coupling a particle model to a reactor model a new method is the fastest. ► ODEs solvers are just the fastest method with constant boundary conditions. ► The new method is an iterative, fractional-step algorithm. ► It is based on the analysis of the characteristic times of each phenomenon.
