摘要： The present invention discloses a SCM-34 molecular sieve, preparation method therefor and use thereof. The SCM-34 molecular sieve comprises aluminum, phosphorus, oxygen and optionally silicon. In the XRD diffraction data of the molecular sieve, a 2θ 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, meeting the different needs for catalysts in the chemical production.

摘要： The present invention relates to a ZSM-5 molecular sieve catalyst, a preparation method therefor and an application thereof. In the catalyst, the ratio of the amount of skeleton aluminum located at the intersection of the straight pore channels and the sinusoidal pore channels to the amount of skeleton aluminum inside the straight pore channels and the sinusoidal pore channels is 1.4:1-10:1, the silica-alumina molar ratio SiO2/Al2O3 is 80-1500, and the microporous pore volume may account for 70% to 92% of the total pore volume. When used for producing propylene and ethylene by olefin catalytic cracking, the catalyst of the present invention has characteristics of a low reaction hydrogen transfer index, a high stability, a high conversion rate of raw material olefin, and a high selectivity of products of propylene and ethylene.
