US Classification:

241 18

Abstract:

A method for producing particles having a controlled particle size from agglomerated material is provided. Agglomerated material is passed through a beater mill and subjected simultaneously to the beating action of a plurality of blades and a vigorous stream of air as the agglomerated material impacts the peripheral screen of the beater mill. Catalyst or catalyst support particles having a readily controlled particle size and pore volume as well as narrow particle size distribution, are obtained as a result of the invention particulation method.
