Abstract
Catalytic oxidation of volatile organic compounds(benzene, toluene, xylene) over transition metals/ALO-6 catalysts was investigated in a fixed bed flow reactor system at atmospheric pressure. The orders of catalytic activities for the complete oxidation of toluene were Cu>Mn>Fe>V>Mo>Co>Ni>Zn for 15% transition metals/ALO-6 catalyst system. Increasing the calcination temperature resulted in decreasing the specific surface areas of catalyst, subsequently the catalytic activity. The loading of Cu on ALO-6 had a great effect on the catalytic activity and 5% Cu/ALO-6 catalyst showed higher catalytic activity, which may be contributed to the uniformly distributed active sites. Benzene, toluene and xylene were completely oxidized to carbon dioxide over 5% Cu/ALO-6 catalyst at over
상압유통식 고정층반응기를 이용하여 전이금속을 ALO-6에 담지한 촉매상에서 휘발성유기화합물인 벤젠, 톨루엔, 자일렌의 촉매산화에 관하여 조사하였다. 15% 전이금속/ALO-6 촉매상에서 톨루엔의 완전산화반응에 대한 활성의 크기는 Cu>Mn>Fe>V>Mo>Co>Ni>Zn의 순서였다. 15% Cu/ALO-6 촉매에서 소성온도의 증가는 비표면적을 감소시켰고 결과적으로 활성은 감소하였다. Cu/ALO-6촉매계에서 Cu의 담지량이 5%일 때 활성이 우수하였다. 5% Cu/ALO-6촉매상에서 벤젠, 톨루엔, 자일렌은 반응온도
