1. having a Si-Al catalysis material for boehmite crystal phase structure, in terms of oxide weight, its anhydrous chemical expression is:

  • (0~

    0.2) Na2O (30~

    33) SiO2(67~

    70) Al2O3, its specific surface area is 300~

    500m2/ g, pore volume is 0.5~

    1.5ml/g, and average pore size is 8~

    15nm, it is characterised in that 200 DEG C of infrared B-acid of the pyridine recorded of this catalysis material are 0.085~

    0.100 with the ratio of L acid.
