Biomass has the highest potential to contribute to a sustainable energy supply. Gasification is a process that converts carbonaceous materials, such as coal or biomass, into a rich gas in carbon monoxide and hydrogen by reacting the raw material at high temperatures with a controlled amount of oxygen and/or steam. The use of air as gasifying agent typically leads to a reduction of the CV of the syngas due to the dilution with nitrogen. The...
