다국어 초록 (Multilingual Abstract)

A quartz type gasification reactor was designed and used for pyrolysis and gasification of sawdust, ricestraw and ricehusk. The initial reaction temperature was 350℃, and up to 550℃ to complete pyrolysis and gasification reaction. In order to examine the effect of catalyst on reaction temperature, K₂CO₃ and Na₂CO₃ as catalyst were also used.
The product gas mixtures are identified to be CO, CO₂ , CH₄ and GH₃CHO etc. by Gas Chromatography and Mass Spectrometer.
The highest gas volume of the gasified sawdust at 550℃ amounts to 1809㎖/g of sawdust, even though the yield and composition of this product gas are depending on the reaction temperature of the reactor and catalyst used.
