  • Patent number: 9963350
    Abstract: The present invention pertains to the field of molecular sieve synthesis, and relates to a synthesis method of ZSM-5 type molecular sieves. In this method, natural minerals, i.e., natural kaolin and natural diatomite, are used as the total silicon source and aluminum source required for the molecular sieve synthesis, and these two natural minerals are calcinated and subjected to acidic (alkaline) treatment before they are mixed at a certain ratio, and then crystallized under hydrothermal conditions to obtain the product, a ZSM-5 type molecular sieve. The ZSM-5 type molecular sieve obtained by the method according to the present invention is a hierarchical porous material having a crystallinity of 70% to 120% as compared to conventional ZSM-5 type molecular sieves synthesized by using pure chemical reagents, and the silica-to-alumina ratio in the molecular sieve product may be adjusted by varying the ratio of the two minerals in the raw materials for the synthesis.
