산화동을 건식탈황제로 이용하기 위하여 세공분포도가 서로 다른 세 가지 유형의 구형 Υ-Al₂O₃에 산화동을 담지시킨 후 담지노동에 따른 반응 흡착능력을 평가하였다.
실험결과 반응흡착 능력은 담체의 세공분포도와 밀접한 관계를 갖고 있으며 고른 세공분포도를 갖는 담체가 산화동을 고농도로 담지시킬 수 있음을 알았다.
본 연구에서 최적 조건은 단위 반응흡착량을 기준으로 할 때 반응온도 450℃, 아황산가스 농도 2,000ppm, 담지농도 6wt%였으며 ALO-3 담체의 경우 산화동 10g당 아황산가스 5.10g을 처리하여 최대치를 보였다. 흡착 처리능력을 기준으로 할 때는 담지농도 14wt%에서 KHT와 X-5 담체가 ALO-3 담체보다 산화동 10g당 1.15-1.55g의 아황산가스를 더 반응흡착할 수 있었다.

To use copper oxide as a dry desulfurizer the reactive adsorption capability was evaluated after it was impregnated in three types of spherical γ-Al₂O₃ possessing diifferent pore size distribution. As a result, it was found that the reactive adsorption capability has a close correlation with the pore size distribution of the carrier, and that the carrier having even pore size distribution was able to impregnate copper oxide in high concentration. In this study, on the basis of unit reactive adsorption capacity, the optimum conditions were found to be the reac-tion temperature 450℃, the sulfur dioxide concentration 2,000 ppm and the mpregnation concentration of 6wt%, which was evaluated to the maximum value of sulfur dioxide 5.10g per 10g of CuO when the carrier ALO-3 was used. Based on the adsorption treatment capability, the carriers, KHT and X-5, were able to adsorb more sulfur dioxide than ALO-3 by 1.15-1.55g per 10g of CuO in the impregnation concentration of 14wt%.
