1. a method for alkali free metal ion system synthesis Beta molecular sieve, is will to include aluminum source, silicon source and haveMachine template, in interior raw material stirring mixing, forms the synthetic system that solid particles surface is wetted by the solution,Then in hermetic container at 110-130 DEG C crystallization 10-30 hour, crystallization 36-50 at 140-160 DEG CHour, it is characterised in that in described synthetic system, composition is expressed as with mol ratio:

  • SiO2/Al2O3=15-50, organic formwork agent/SiO2=0.08-0.12, H2O/SiO2=6-8, described silicon sourceSelected from having specific surface area >

    400m2/ g, pore volume >

    =0.7mL/g, the silica gel of granularity >

    =100 μ

    m and/orAlusil, one or more in hydrated alumina, aluminium hydroxide and Alusil of described aluminum source.
