Abstract of the Disclosure Small size alumina particles of controlled sizes suitable for use as a catalyst support can be made from an acidified alumina slurry by spraying under nonatomizing conditions from a nozzle with a gas or inert fluid used to disperse the slurry into small droplets. The droplets can either be sent through an ammoniated kerosene column or the acidified slurry can be spray dried. Small alumina spheroids are produced, which after calcination, have controlled size diameters from about 0.01mm. to about 2.0 mm.
