CATALYST FOR OXIDIZING SO2 TO SO3 AND UTILIZATION OF THE CATALYST IN A METHOD FOR PRODUCING SULFURIC ACID
摘要
<p>The invention relates to a catalyst for converting SO2 with molecular oxygen into SO3. The catalyst is suited for continuous operation at temperatures of 700 ~C and higher when said catalyst is comprised of a porous supporting material and an active component which is joined to the supporting material. The active component is made up of 10 to 80 wt. % iron. The supporting material is a BET-surface ranging from 100 to 2000 m2/g and comprises a SiO2 content of at least 90 wt. %. The weight ratio supporting material:active component ranges from 1:1 to 100:1.</p>
