Manufacture of chabazite type structure silicoaluminophosphate consists of hydrothermal processing based on an organoaluminophosphate and a source of silica

NOVELTY – The manufacture of chabazite type structure silicoaluminophosphate uses a 0.2-1.0 silica:alumina ratio production sequence based on an organoaluminophosphate and a source of silica in an aqueous suspension. Also claimed is the product of the process. CLAIMED PRODUCT – The product is prepared hydrothermally at high temperatures, and silicoaluminophosphate calcination yields a molecular sieve more economical than conventional molecular sieves. USE – In industrial chemistry.

Main Application Field

E33 (Compounds of Be, Mg, Ca, Sr, Ba, Ra, Sc, Y, La, Ac, Al, lanthanides (Rare-earths), Th.); J01 (Separation – including evaporation, crystallisation, solvent extraction, chromatography, dialysis, osmosis including drying gases and/or vapours, and separation of solids from gases, liquids and other solids. Isotope separation, filter materials (including molecular sieves for separation), and centrifuges (except where used for analysis) (B01D, B03, B04, B07B).)
