  • SCM-34 MOLECULAR SIEVE, PREPARATION METHOD THEREFOR AND USE THEREOF
    Publication number: 20230356201
    Abstract: A SCM-34 molecular sieve, preparation method therefor and use thereof are provided. The SCM-34 molecular sieve contains aluminum, phosphorus, oxygen and optionally silicon. In the XRD diffraction data of the molecular sieve, a 2? degree of the strongest peak within the range of 5-50° is 7.59±0.2. The SCM-34 molecular sieve has a new skeleton structure and can be used to prepare a metal-containing AFI type molecular sieve or an SAPO-17 molecular sieve.
