Process for the catalytic reaction of a mixture containing O2 and SO2 that involves Passing the mixture at temperatures of 350 to 600 degrees Celsius for a First Catalyst V2O5 material and INERYou and at temperatures of 500 to 750 degrees Celsius for a Second Catalyst containing 3 to 30 of ixido 3 to 30 Iron and Arsenic oxide.

摘要

A gas mixture with molecular oxygen and 15 to 60%.SO2 flows through a First Catalyst Layer which contains a catalyst containing Vanadium PENTOXIDE and immediately below through a second layer of CATAlizador containing Catalyst with iron content.The gas mixture is LED into the first Catalyst Layer, which contains granular Catalyst V2O5 and 20% to 80% in PESOD catalytically inactive and Inert material,With Inlet temperature of 350 to 600 degrees C. then leads immediately to the gas mixture in the second layer of Catalyst contains 3 - 30% by weight of arsenic oxide.Gas is a product with a Content of SO3 SO3 ratio in volume; SO2; 0.1 maximum.
