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 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.

SCM-34 molecular sieve, preparation method therefor and use thereof

An aluminophosphate molecular sieve SCM-18 has a schematic chemical composition, expressed on a molar basis, of AlO.n PO, in which n represents a phosphorus to aluminum molar ratio, and is in a range of about 0.8-1.2. The aluminophosphate molecular sieve has a unique X-ray diffraction pattern, and can be used as an adsorbent, a catalyst or a catalyst carrier.

Aluminophosphate molecular sieve SCM-18, its preparation and application thereof

A novel silicoaluminophosphate molecular sieve has a schematic chemical composition, expressed on a molar basis, of mSiO&#xb7;AlO&#xb7;nPO, in which m represents the molar ratio of SiOto AlOand is in a range of about 0.005-0.15, and n represents the molar ratio of POto AlOand is in a range of about 0.7-1.1. The silicoaluminophosphate molecular sieve has a unique X-ray diffraction pattern, and can be used as an adsorbent, a catalyst or a catalyst carrier.
