1. comprise a composition for crystal structure, wherein this crystal structure of at least a portion is the molecular sieve with chabasie skeleton, and this skeleton is comprised of 36 T-atoms that are selected from silicon, aluminium and phosphorus;

  • The skeleton phosphorus that wherein said molecular sieve comprises the about 5.0mol% of about 0.05-, based on the total mole number of framework silicon, aluminium and phosphorus in described molecular sieve;

    WithThe silica of wherein said molecular sieve and the mol ratio of aluminium oxide are at least about 10.
