The energy from biomass can be utilized through the thermochemical conversion process of pyrolysis and gasification. The process involves solid phase and fluid phase interactions. Computational Particle Fluid Dynamics (CPFD) tools are most commonly used for simulations. The chemical processes involved is described by reaction rate expressions and equilibrium constants. These expressions are often not well studied, but rather adapted from previous studies in lack of better knowledge. Methodology and tools are presented to aim in the selection and optimization of rate expressions for a particular process. Simulation tools for reactions in batch or plug-flow conditions are shown applicable to study selected chemical reactions in detail. Results from one such study is compared to CPFD as well as CSTR results of a gasification process. The reaction scheme for the simulation model could be simplified.
