Catalyst for sulfuric acid contact process |
| abstract |
A catalyst for oxidation of SO 2 to SO 3 , which can be used as a fluidized bed catalyst. An abrasive resistant support is formed by adding silica filler and a clay binder to a silica sol; adding hydrated magnesium oxide to the resulting mixture, to form a gellable composition; dispersing the gellable composition in a liquid to form gel spheres; calcining the spheres; and treating them with an acid to remove acid soluble components. After the acid treatment, the support is impregnated with an alkali metal vanadate solution and calcined. |
