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...

description |
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 industrial sized honeycombtype catalyst was studied at lab and pilotplant scale. The evolution of SO2 conversion and some physico-chemical properties of the catalyst with time in operation were examined. The 7-8 wt.% of sulfate deposition on the fresh catalyst had no influence on the catalytic activity at steady state conditions. The catalyst showed SO2 to SO3 conversion value of 80-90 vol.% operating at a temperature of 450ºC and space velocities of 3000-6150 h-1 (NTP). |
