[ Thus, what is claimed is:] [1.] A fluid SO.sub.x additive system comprising SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst particles and SO.sub.3 absorbent particles wherein:(1) the SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst particles comprise: (a) a SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst co
[ Thus, what is claimed is:] [1.] A fluid SO.sub.x additive system comprising SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst particles and SO.sub.3 absorbent particles wherein:(1) the SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst particles comprise: (a) a SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst comprised of a metal selected from the group consisting of cerium, vanadium, platinum, palladium, rhodium, molybdenum, tungsten, copper, chromium, nickel, iridium, manganese, cobalt, iron, ytterbium, and uranium; and (b) a binder made from a material selected from the group of metal-containing compounds consisting of calcium aluminate, aluminum silicate, aluminum titanate, zinc titanate, aluminum zirconate, magnesium aluminate, magnesia, alumina (Al.sub.2 O.sub.3), aluminum hydroxide, an aluminum-containing metal oxide compound (other than alumina (Al.sub.2 O.sub.3)), clay, zirconia, titania, silica, clay/phosphate, bastnaesite and which contains no more than about 10 weight percent aluminum hydroxide and no more than about 10 weight percent alumina (Al.sub.2 O.sub.3); and(2) the SO.sub.3 absorbent particles are physically separate and distinct from the SO.sub.2 .fwdarw.SO.sub.3 oxidation catalyst particles and comprise a metal oxide selected from the group consisting of hydrotalcite, hydrotalcite-like compositions, magnesia, magnesium acetate, magnesium nitrate, magnesium chloride, magnesium hydroxide, magnesium carbonate, magnesium formate, magnesium aluminate, hydrous magnesium silicate, magnesium calcium silicate, calcium silicate, alumina, calcium oxide and calcium aluminate.
