Platinum monolithic catalyst for SO2 abatement in dust-free flue-gas from combustion units

A catalytic oxidation process of traces of SO2 to SO3 for the treatment of dust-free flue-gas from power stations and some special waste incinerators has been developed. The catalyst was prepared by impregnation of platinum precursors on alumina/silicates-based material. The behavior of this industr...
