High temperature air-blown gasification experiment of woody biomass was conducted in an entrained down-flow type gasifire. Air was blown as the gasifying agent instead of oxygen to improve the gasification process performance. To archive the higher temperature (over 1273 K), pulverized wood was used as the feed stock of gasification experiment. Air-blown gasification process was evaluated by measuring temperature in the gasifire and produced gas composition against O/C ratio. Carbon to gas conversion, cold gas efficiency and heating value of produced gas in an air-blown gasification experiment was also calculated. These gasification behaviors were compared with that in oxygen-blown gasification experiment. It was found that gasification process with air could be performed as well as gasification with oxygen.
