Biomass gasification and in-bed contaminants removal: Performance of iron enriched Olivine and bauxite in a process of steam/O2 gasification

► Iron enriched-Olivine and bauxite were tested in process of steam/O2 gasification. ► Relevant differences were found in the raw gas for tar and particulate contents. ► Bauxite was effective in the removal of KCl, but not towards NaCl. ► No significant differences were found on gas composition and gas yield.
