1. prepare a method for beta-molecular sieve with oil shale, it is characterized in that comprising following content:

  • oil shale waste is carried out alkali treatment by (1), roasting, product of roasting joins in the template aqueous solution and carries out immersion treatment;

    (2) in material in step (1), add silicon source, aluminium source, alkali, water and template, be mixed to get gel masses;

    (3) gel masses that step (2) is obtained is carried out hydrothermal crystallizing process, washing, dry, obtain product beta-molecular sieve.
