초록

The fixed bed gasification reactor with 1 m hight and 10.2 cm diameter was utilized for the hydrogen production from biomass wastes. Lauan sawdust was used for non-catalytic and catalytic gasification reaction as a sample in the fixed bed reactor. The fixed bed temperature and catalyst are the major variables affecting the process operation. Thus, the effect of fixed bed temperature and the catalysts on gas composition were studied at the temperature range from $400^{\circ}C$ to $700^{\circ}C$. The yield of hydrogen was increased at higher temperature in the fixed bed reaction. Fractions of hydrogen, carbon monoxide and methane gas in the product gas increased when sodium carbonate ($Na_2CO_3$) and potassium carbonate ($K_2CO_3$) catalysts were used. Furthermore, sodium carbonate catalyst was more effective to obtain higher hydrogen yield compared to potassium carbonate catalyst.

바이오매스 폐기물로부터 수소를 생산하기 위하여 1 m 높이와 10.2 cm의 외경을 갖는 고정층 가스화 반응기를 이용하였다. 촉매를 첨가하지 않은 나왕톱밥과 촉매를 혼합한 나왕톱밥이 시료로 사용되었다. 고정층 가스화 실험 변수로써 온도와 촉매가 공정운전에 미치는 영향을 파악하였다. 반응온도가 $400^{\circ}C$에서 $700^{\circ}C$ 범위에서 온도변화에 따른 생성기체 조성의 변화는 온도증가에 따라 수소 생성량이 증가하였으며, 수소, 일산화탄소와 메탄의 생성분율은 탄산나트륨($Na_2CO_3$)과 탄산칼륨($K_2CO_3$) 촉매 사용에 의해서 증가하였다. 또한, 탄산나트륨 촉매는 탄산칼륨 촉매에 비하여 수소생산 효율에 보다 효과적인 것으로 판명되었다.
