Analysis of Wood Biomass in Bubbling Fluidized Bed Reactors

Abstract:

This article analysis the computational simulation of wood's gasification in a bubbling fluidized bed reactor. Most articles about this topic, on homogenous reactions, don’t consider methane reforming. However, this article has taken this into consideration in the process of gasification. The bubbling fluidized bed reactor was used in the simulation, in which the advantages of a good mixture is presented, one which provides high rates of mass and heat transfer. The gas-solid flow that occurs in this reactor was described through mass, energy, momentum, and chemical species balances. The model used for the simulation was the computational fluid dynamics (CFD), by means of an open-source program named MFIX (Multiphase Flow with Interphase eXchange). It is concluded that methane reforming is important in the process of gasification.
