전이금속으로 개질된 Red Mud 촉매상에서 휘발성유기화합물 제거 = Removal of Volatile Organic Compounds on Red Mud Catalyst Modified with Transition Metals

다국어 초록 (Multilingual Abstract)

Red mud(RM), a byproduct of alumina production, was incorporated with a transition metal, which was used as a catalyst for oxidation of volatile organic compounds (VOCs). RM was treated with hydrochloric acid and ammonia and then calcined at 400 ℃(CRM). Cu, Mn, Co, Ni, and Zn were used as the transition metals for the modified CRM catalyst. The physical and chemical properties of each catalyst were investigated by BET, SEM, XRD, TPR and FTIR analysis. The transition metals improved the reaction activity of CRM. The order of activation of each catalyst according to transition metals was Cu/CRM > Mn/CRM> Co/CRM > Ni/CRM ≥ Zn/CRM > CRM. The activity order of the catalysts was associated with the mobility of the lattice oxygen of the catalyst. In addition, the catalytic activity with respect to the VOC molecule (benzene, toluene, and xylene) was related to the ionization potential energy of the aromatic compound.
