Use of a reactor agitated by a screw-type system for the synthesis of faujasite lsx

摘要

The synthesis of faujasite LSX comprises ripening and crystallising a gel of molar composition 0.7-0.8 sodium oxide /sodium oxide + potassium oxide ((Na2O)/(Na2O+K2O)), 91-130 water/aluminium oxide (H2O/Al2O3), 1.8-2.2 silicon dioxide/aluminium oxide (SiO2/Al2O3) and 5.5-8 (Na2O+K2O)/Al2O3. The gel is stirred by an Archimedes screw type agitator during ripening and crystallisation.
