Resumen


Numerical simulations are powerful tools to study and analyze gasification processes. Among the applicable models, Computational Fluid Dynamics (CFD) models allow a detailed description of the phenomena taking place inside gasification reactors [1, 2]. The aim of this work is to provide a tool for the development of the terms associated to reaction kinetics needed for CFD models. Thus, the unsteady state steam gasification of a spherical porous char particle using the reaction-diffusion model, presented by [3], is implemented. This model simultaneously describes the kinetics of gasification reactions and the diffusion transport of gaseous species inside the particle.
