Abstract

Process for continuous preparation of crystalline zeolite 4A by direct mixing in an unstirred reactor of aqueous solutions of sodium silicate and aluminate, bringing the hydrogel formed into contact with a base stock of sodium aluminate, crystallisation, washing, filtration and optionally drying.
