Process simulation of biomass gasification with steam as gasification agent

ABSTRACT

Among all renewable energies, biomass has been receiving more attention because of its availability and economic advantages. In this study, a thermodynamic model was developed using a commercial simulator to analyze the gasification behavior of biomass (pine sawdust) particles in the presence of CaO as CO₂ sorbent. The developed model was validated with the experimental results showed a good agreement. It was found that H₂ and CO₂ increased, as the SBR increased, while an opposite trend is obtained for CO and CH₄. The simulated results also showed that the CO₂ conversion ratio (CCR) increased from 31.12% to 59.45% increased as the SBR increased from 0.25 to 1.0.
