Synthesis method of SSZ-13 molecular sieve

The invention provides a synthesis method of an SSZ-13 molecular sieve. A USY molecular sieve or Beta molecular sieve with adsorbed N,N,N-trimethyl-1-adamantanamine cations is used as a structure guide agent to synthesize the SSZ-13 molecular sieve together with an aluminum source, a silicon source, an alkali source, water and mixed seeds, thereby greatly reducing the consumption of the expensive template N,N,N-trimethyl-1-adamantanamine cations in the traditional method, and obviously lowering the cost for synthesizing the SSZ-13 molecular sieve. The method can enhance the crystallization rate of the SSZ-13 molecular sieve and shorten the required crystallization time, and thus, is more beneficial to industrial production. The SSZ-13 molecular sieve synthesized by the method has high crystallinity and favorable hydrothermal stability; and the synthesized SSZ-13 molecular sieve can be used as an MTO (Methanol To Olefins) catalyst and can also be used as an automobile tail gas treatment catalyst support. 本发明提供
