ALUMOPHOSPHATE MOLECULAR SIEVE SCM-18, ITS PREPARATION AND USE Russian patent published in 2024 - IPC B01J29/04 C01B37/04 C01B39/02 B01J20/08 

FIELD: molecular sieve technology.

SUBSTANCE: invention relates to the aluminophosphate molecular sieve, its preparation and use. An aluminophosphate molecular sieve for adsorbent is disclosed. The sieve is characterized by a schematic chemical composition expressed on a molar basis by formula Al₂O₃⋅nP₂O₅ in which n represents the molar ratio of phosphorus and aluminum, and ranges from 0.8 to 1.2. The molecular sieve is characterized by an x-ray diffraction pattern exhibiting a relative intensity profile, which is presented in the following table:

Also the following is disclosed: an aluminophosphate molecular sieve for catalyst and catalyst support, a method of producing the aluminophosphate sieve, and the use of an aluminophosphate sieve as an adsorbent, catalyst, and catalyst support.

EFFECT: new aluminophosphate molecular sieve, its preparation and use, and this sieve should be characterized by a unique x-ray diffraction pattern, and it should be suitable for use as an adsorbent, catalyst or catalyst support.
