ABSTRACT:
High-strength, non-agglomerated uniform porous microspheres of silica produced by spray drying a mixture comprising a colloidal silica sol and an additive selected from ammonium citrate or urea; an attrition resistant catalytic composite consisting essentially of metal crystallites such as palladium, platinum-palladium on said silica microsphere and method for preparing the same; and an improved process for making hydrogen peroxide from the direct combination of hydrogen and oxygen in the presence of said attrition resistant catalytic composite.
