Preparation of spheroidal alumina particulates

摘要

Spheroidal alumina particulates well adapted as catalysts or catalyst supports and having enhanced pore volumes are facilely prepared by drop coagulating an aqueous suspension or dispersion of alumina, or an aqueous solution of a basic aluminum salt, said suspension, dispersion or solution comprising an oil-in-water emulsion, and then recovering, drying and calcining the gelled particulates which result.
