Total combustion of methyl ethyl ketone and benzyl alcohol as two models of volatile organic compounds (VOCs) using catalytic method was studied over γ-Al2O3 and Mn/γ- Al2O3 catalysts. Catalyst (Mn/γ-Al2O3) was prepared by wet impregnation and characterized using XRD, BET, ICP-AES and SEM methods and the nanostructure of the catalyst were approved. The activity of the catalysts was measured in a catalytic packed bed reactor under atmospheric pressure and different reaction temperatures at range 150 to 450°C. The studies confirmed that manganese supported on γ-Al2O3 can be suitable for the abatement of the mentioned pollutants from contaminated air and hopefully …
Investigation Of Deactivation Of Transition Metal Oxide Catalysts Supported On Γ-Al2o3 During Catalytic Oxidation Of Some Oxygen Containing Vocs In A Tubular Reactor, Hosein Afshary

It is necessary to decrease the emission of Volatile organic compound ( VOCs ) to air and among of all destructive techniques used for decreasing these compounds, Catalytic Oxidation is considered a suitable technique but deactivation of catalysts through catalytic processes is one of the major problems and most be studied. In this Project, at First, gamma alumina supported metal oxide catalysts were made and also industrial Pt catalyst was prepared. Then structure of these catalysts was studied using XRD, SEM and FT-IR techniques. These techniques approved the nanostructure of catalysts. The amount of supported metals in each catalyst was …
