Synthesis of large single crystals of templated Y faujasite

Ferchiche S, Valcheva-Traykova M, Vaughan DEW, Warzywoda J, Sacco A

Large single crystals of zeolite Y with diameters up to 210-245 mum and Si:Al = 1.71 have been synthesized from a reaction mixture (4.76Na(2)O:1.0Al(2)O(3) : 3.5SiO(2) : 454H(2)O : 0.6T(2)O : 5TEA) comprising fumed silica (Cab-O-Sil M5). sodium aluminate, and the template bis( 2-hydroxyethyl)dimethylammonium chloride (TCl) in an aqueous triethanolamine (TEA) cosolvent.
