Abstract

An experimental study of a fixed bed reactor is shown in this paper. Pine wood sawdust was used to feed the reactor in order to get a more efficient conversion gasification process. The Discrete Phase Method (DPM) methodology was applied in a commercial Computational Fluid Dynamics (CFD), the numerical study included the processes of combustion, gasification and pyrolysis. A two-dimensional modelling for the geometry was used in conjunction with 0.001 mm diameter spherical particles. The interaction of particles (discrete phase) with the continuous phase was performed by modifying the transport equations. The numerical gasification model results were validated with experimental temperature profiles and composition of synthesis gas produced in the reactor. The influence of concentration of an oxidant agent was numerically investigated. The maximum temperatures reached for the processes of combustion, gasification, and pyrolysis were 2207.91, 1559.47 and 1097.55 K respectively. The gasification temperature was computed and showed a standard deviation of 5.2%.
