수소에 의한 In₂O₃환원반응속도론적 연구 = Kinetics on In₂O₃Reduction by Hydrogen

국문 초록 (Abstract)

수소에 의한 In₂O₃의 환원반응을 열증량분석기를 이용하여 실험하였다. 환원반응이 일어나는 온도는 300℃이상이었고 반응온도에 따라 반응속도는 급격히 증가하였으나. 수소의 유량에 따라서는 크게 변화하지 않았다. 환원반응기구는 unreacted shrinking core model 이 잘 맞았으며, 고체에 표면반응이 율속단계였다. 반응속도는 수소농도에 대해 일차반응이었다.

The reduction of In₂O₃by hydrogen have been investigated by using thermogravimetric analyzer. The reaction proceeded smoothly at 300℃. The effect of reaction temperature on reaction rate was great, but the rate was not depended on hydrogen flow rate. The unreacted shrinking core model was well fitted to the reaction of In₂O₃by hydrogen. The chemical reaction on the solid surface was rate controling step. The reaction rate was 1st order with respect to hydrogen.
