ABSTRACT:
Disclosed is a method for subjecting a finely divided solid to a series of processing steps on a single horizontal vacuum belt filter wherein the processing includes a liquid-solid mass transfer function, such as ion-exchange, carried out by percolation, and this step is followed by at least one step, such as washing, in which rapid passage of a large volume of liquid through the solid takes place. The method is used to ion-exchange zeolitic microspheres in the production of a fluid cracking catalyst.
