FIELD: catalyst production. ^ SUBSTANCE: zeolite catalysts in the form of micropheres including zeolite and oligomeric silica characterized by high mechanical strength are prepared by (i) rapid drying of suspension, supplemented by tetraalkyl ortho-silicate if needed, obtained from zeolite synthesis by hydrothermal treatment, at antogenous pressure, of reaction mixture containing tetraalkylammonium hydroxide as template agent, and (ii) firing the dried product. ^ EFFECT: increased mechanical strength of catalyst. ^ 28 cl, 4 dwg, 4 ex |
