摘要: Alumina spheres are formed by peptizing alumina slurries, centrifugates, and filtercakes, aging and dropping the peptized material through a hydrocarbon filled column. The improved method avoids the drying and reslurrying of alumina powders currently used and provides a method whereby harmful ions such as chloride and sulfates can be excluded from the alumina.
