Abstract

Alumina-supported indium and gallium oxide catalysts were prepared by excess solvent impregnation, characterized and tested for the reduction of NO x by ethanol in Lean Burn Conditions. The promotion of alumina by “poor” metals showed an interesting ability to selectively reduce NO x to N2. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Several samples of exhaust diesel soot are investigated by inverse gas chromatography and linear solvation energy relationship (LSER) modelling according to their soluble organic fraction content and their time of exposure in oxidative conditions. The results demonstrate the evolution of the adsorptive properties of the studied materials towards volatile compounds during the oxidation under NO2. [Copyright &y& Elsevier]
