Catalytic gasification of woody biomass in an air-blown fluidized-bed reactor using Canadian limonite iron ore as the bed material

► Limonite iron ore is a catalytic bed material for biomass fluidized-bed gasification. ► Limonite iron ore is more active than olivine for tar reduction. ► The iron ore was less active than olivine for producing combustible gases. ► The use of the iron ore produced a higher yield of hydrogen than that of olivine.
