1. the method that two kinds of microporous crystals coordinate conversion to prepare SAPO-34 molecular sieve, it is characterised in that through following step:

  • by crystalline substanceBody micropore aluminium phosphite NKX-2, A type molecular sieve, organic formwork agent and water mix homogeneously, temperature is 15~

    35 DEG C, then shouldMixture hydrothermal crystallizing 3~

    6 days under 165-200 DEG C and self-generated pressure, then cool down, wash, separate, room temperature is dried and producedThing, reaction mass has following mole of composition;

    Al2O3

    P2O3

    SiO2

    R∶

    H2O=1.0;

    1.0;

    0.67;

    (2.0~

    3.0);

    (35~

    100).
