ABSTRACT:
The useful life of SO.sub.X additives having a SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst component and a SO.sub.3 absorption component can be extended by employing each of these components as separate and distinct physical particles, pellets, etc., with each component having large proportions of certain ingredients and having small proportions of certain other ingredients.
