Abstract

유동층 전극반응기내의 반응속도분포를 검토하였다. 산성구리용액중 구리전착반응계에서 연속상유효비전기전도도（Ks）에 대한 분산상 유효비전기전도도(K_m)의 비 K_m/K_s = 4∼20 정도이면 반응의 대부분이 격막인접 영역(격막으로부터 약 0.8 ㎝까지)에서 일어나고 있으며, K_m/K_o = 0.07∼0.2 정도이면 반응은 거의 전류공급판 인접영역(전류공급판으로부터 약 0.6 ㎝까지)에서 일어나고 있다. 그리고 K_m/K_s ≃ 1 이면 반응기 양끝 부분이 활성영역임을 알았다.

The distribution of the reation rate in a fluidized bed electrode reactor was studied. The distribution was strongly influenced by the effective specific electrical conductivities of the continuous electrolyte phase（K_s） and of the dispersed particle phase(K_m).
For the ratio of conductivities（K_m/K_s） in the range of 4∼20, the reaction mainly occurred in the diaphragm region(0∼0.8 ㎝ from the diaphragm). However, the main reaction occurred in the feeder region(0∼0.9 ㎝ from the feeder) for the ratio of K_m/K_s in the range of 0.07∼0.2.
For the case of K_m≃K_s, the reaction occurred mostly at both ends of the reactior.
