  • HIGHLY EFFICIENT SOLIDOTHERMAL SYNTHESIS OF ZEOLITIC MATERIALS
    Publication number: 20200317532
    Abstract: A process for preparing a zeolitic material having a zeolitic framework structure which exhibits a molar ratio (aAl2O3):SiO2 or a crystalline precursor thereof, comprising (i) preparing a mixture comprising H2O, one or more compounds comprising Si from which SiO2 in the zeolitic framework structure is formed, said one or more compounds comprising a silica gel exhibiting a molar ratio (c H2O):SiO2 and optionally one or more compounds comprising Al from which Al2O3 in the zeolitic framework structure is formed; (ii) subjecting the mixture obtained in (i) to crystallization at a crystallization temperature in the range of from 110 to 350° C., preferably in the range of from 190 to 350° C., and for a crystallization time in the range of from 0.1 to 48 h.
