ABSTRACT:
A down-flow apparatus for continuous crystallization of zeolites comprises a vertically-positioned reactor having at least one reactor inlet port at the top thereof and at least one product egress port at the bottom thereof. The reactor is equipped with an inside stirrer extending throughout the length of the reactor and with heating means surrounding the reactor. Product and spent liquids are collected into one or more product collectors at the bottom of the reactor wherein spent liquids are decanted from the crystalline product settling to the bottom. The entire assembly is pressurized with an inert gas, e.g., air, nitrogen, helium (He), to prevent water boiling at the reaction temperature.
