고정발생원으로부터 나오는 황산화물과 질소산화물을 제올라이트 담체상의 산화구리를 이용하여 제거하는 실험을 하였다. 실험결과 CuO/Zeolite는 배기중 SOx 및 NOx의 제거에 적합한 만응물이며 반복재생 후에도 효율이 떨어지지 않는 것을 알 수 있었고 최적 반응온도는 400-450℃이었다. SO₂ 제거효율은 온도가 높을수록 증가하였으나 550℃ 이상에서는 생성된 CuSO₄의 열분해로 인하여 감소하였고, SO₂와 함께 NO를 제거시킬 경우에도 SO₂의 반응 및 재생에는 영향이 없었으며, NO의 제거율은 거의 100%이었다. CuO/Zeolite와 SO₂의 반응은 grain model을 사용하여 SO₂농도에 대하여 1차인 화학반응율속으로 설명할 수 있었으며 반응속도상수는 다음과 같다.
k (cm/s) = 7.92exp[-12,450(cal/mol) /RT]

Removal of SO_X and NO_X from flue gas was experimented by using cupric oxide supported on zeolite. Experimental results showed that CuO/Zeolite is a good reactant for the removal of SO₂ and NO from flue gas and the optimum reaction temperature is 400℃ to 450℃. Removal efficiency of SO₂ was not decreased even after repeated cycles of removal and regeneration and it was increased with temperature but decreased at above 550℃ because of the thermal decomposition of CuSO₄. In case of simultaneous removal of SO₂ and NO, the efficiency of the removal and the regeneration of SO₂ was not changed by the NO reaction and in particular the removal efficiency of NO was approx-imately 100 percent. The reaction of CuO/Aeolite with SO₂ could be well explained by the grain model using 1st order chemical reaction control and the reaction rate constant was obtained as
k(cm/s)=7.92exp[-12,540(cal/mol)/RT].
