SAPO molecular sieves is a series of new silicoaluminophosphates that were created by the Union Carbide Corporation in 1982. Since then, molecular sieves made of silicoaluminum and its variously substituted atoms have been studied as catalysts. Among this molecular sieves, silicoaluminophosphate SAPO-34 is a molecular sieve that contains a chabazite-based framework that contains 8 membered ring ellipsoids and 3 dimensional channels that are formed by the stacking of double six-rings in the ABC sequence. SAPO-34 is a microporous molecular sieve that has a porosity of 0.38-0.38 nm and a cage size of 1.0-0.67 nm. The space group of the SAPO-34 is R3m, which is part of a trigonal crystal system.
Because of its proper acidity and porous structure, it has a unique capacity for water absorption, this property is used in the production of adsorbents, catalysts, and support for MTO reactions.
