IONIC LIQUIDS AS CATALYSTS FOR SULFURIC ACID PRODUCTION AND CLEANING OF FLUE GASES

摘要

The present paper is concerned with catalytic pollution abatement of sulfur and nitrogen oxides in flue gases from industrial sources. Especially fundamental and applied research on industrial catalysts and their model systems is presented with regards to cleaning of flue gases from fossil fuel based power plants and plants producing sulfuric acid. Combined DeSO_x and DeNO_x processes are very common installations in power plants in the industrialized world since both contaminants cause "acid rain", leading to destruction of forests and lakes as well as corrosion of ancient and modem constructions. In most cases SO_x is removed by wet limestone scrubbing of power plant flue gases, but new waste is produced.
