Abstract
Abstract A novel crystalline aluminosilicate composition denominated "zeolite LZ-133" or simply "LZ-133" and having uniform pore dimensions of approximately 4.3 Angstroms is prepared hydrothermally from a reaction mixture containing as essential reagents, water, alkali or alkaline earth metal oxide, alumina, silica and a quaternary ammonium compound.
