FIELD: sorbents. SUBSTANCE: molecular sieves are prepared from dense gel containing sufficient amount of liquid to transform dense gel into self-sustaining particles. To that end, dense gel in the form of particles or not is heated under crystallization conditions in absence of external liquid phase in order to avoid necessity of removing excess liquid at the end of crystallization phase. EFFECT: increased yield of product. 49 cl
