활성탄과 알루미나에 담지된 Co와 Mo 산화물 촉매의 환원특성 연구를 Cahn Balance를 이용하여 수소 분위기하에서 수행하였다. 승온환원실험 및 Elovich Mechanism 모델을 이용하여 해석된 환원속도실험 결과로부터, 활성탄에 담지된 Co, Mo 촉매계는 알루미나 담지계에 비해 담체와 약한 상호작용을 보이며, 보다 균일한 상태로 담지되어 있음을 제안하였다. X선 회절분석（XRD） 및 산란반사 스펙트럼(DRS)을 이용하여 분석된 산화물 상태의 촉매상태와, 부분적으로 환원된 촉매상에서의 수소 화학흡착 실험 및 에틸렌 수소화 반응 활성으로 나타난 촉매 특성은, 상기 환원특성 연구 결과와 잘 일치하였다.

Reduction characteristics of Co or Mo oxide catalysts supported on activated carbon and alumina was studied under hydrogen atmosphere using a flow microbalance reactor. The results of TPR study and reduction kinetics study analyzed by the Elovich mechanism showed that the catalysts supported on the carbon had higher rate of reduction and lower variation of reduction activation energy with the extent of reduction. This suggested that the carbon support had less and more homogeneous interaction with the metal phases. The precursor oxide states examined by XRD and DRS and the reduced states investigated by ethylene hydrogenation and hydrogen chemisorption were in good correlation with the proposed explanation.
