Abstract

Gasification of biomass using steam enables thermal treatment under a reducing atmosphere that leads to enhanced H2 production. Improved CO concentrations have been observed when CO2 is added as a co-reactive agent. In this work, a biomass gasification process using steam and CO2 in a fluidized-bed gasifier is modeled using ASPEN Plus. The model utilizes Gibbs free energy minimization to predict the effect of operating parameters ...
