FIELD: chemical industry; production of zeolites for subsequent use as components of detergents. SUBSTANCE: alkaline aluminosilicohydrogel is subjected to continuous crystallization, followed by neutralizing residual alkali in zeolite slurry with carbon dioxide and by discharging product. Inventive novelty of method resides in the following: low-frequency pulsation is applied to process flows of reactants; neutralization step is carried out in counter-current mode and with highly turbulized process flows; portion of slurry flow is circulated; feedstock slurry and circulated slurry flow are admitted into neutralization zone in dispersed state. EFFECT: intensification of process; higher product quality. 2 cl
