Abstract

A liquid classification process it provided for powdered catalyst compositions where the removal of ultra fine particles from such composition is desired. A suspension in an inert liquid of catalyst material is prepared which is agitated for a period of time sufficient to distribute at least the smallest particles throughout the liquid On this continuance of the agitation the solids settle and for any predetermined segregation of particles may be effected according to size with an appropriate settling time The depth of the top portion of partially settled suspension which contains catalyst fines may readily be separated from the heavier bottom portion of the suspension Separation may be accomplished by decantation or siphoning off the top portion or by withdrawal of the bottom portion through outlet valve in the lower portion of the treatment vessel.
