Abstract: Biomass Chemical Looping Gasification (BCLG) is a promising route to obtain N2 free high purity syngas. In this work, heat and mass balances were solved to determine the auto-thermal operation conditions that maximize the syngas yield in a BCLG system. A Fe-based oxygen carrier and pine wood as fuel were considered for the simulation. Two methods to control the transference of oxygen between the air reactor (AR) and fuel reactor (FR) were analysed. Syngas yield was higher controlling the oxygen fed to the AR by the air flow (OCM-1) than controlling the oxygen supplied to the FR by the oxygen carrier circulation flow (OCM-2).
