Annotation	The nickel-based catalyst was exposed to the raw gas from gasification of woody biomass with air in a fluidized-bed. Steam reforming reactions led to decomposition of tar and all hydrocarbons higher than CH4 into mainly H2 and CO which further underwent reaction with steam via the water gas shift reaction to CO2. The reforming reactions caused approximately 10-20 % decrease in the lower heating values of the producer gas from the inlet values 5.0–6.5 MJ m-3. The gas yield increased from values 2.4–2.6 m3 kg-1 to values 2.8–3.0 m3 kg-1 on dry biomass basis. The chosen tar removal concept based on combination of dolomite in the fluidized-bed with the secondary catalytic reactor was proved by 20 hours long experiment in which the final tar content below 30 mg m-3 was attained corresponding to more than 97 % tar conversion.
