Catalytic converter, in particular for the recuperation of gaseous sulfur compounds, the small amounts in - and flue gases, and to their by means of guidance in sulfuric, as well as a method using this catalyst
Gaseous sulphur compounds are recovered from combustion gases by contact with, adsorption on and desorption from a catalyst containing 0.5-8% V2O5 and 0.01-10% K2O on Al2O3. Subsequently the gaseous sulphur compounds may be oxidized initially to SO2 and eventually to SO3 in the presence of the same catalyst at an elevated temperature. Oxidation to SO3 may be effected batchwise or continuously in fixed or fluidized bed processes respectively. Optimum results are attained by oxidizing at 430 DEG C.ALSO:Oxidation catalysts comprise essentially Al2O3 with 0.5-8%V2O5 and 0.01 to 10% K2O. The catalyst may take the form of particles of 2-5 mms. or less and may be used in fixed or fluidized beds. Conventional preparative techniques are described.
