<p>Preparing faujasite structure-type EMC-1 zeolite comprises: mixing a mixture of a tetravalent element (X), an alkaline metal or alkaline-earth (M), a mineralizing agent (A) and a nitrogenized organic species (1-(4,7,10,13-tetraoxa-1-azacyclopentadec-1-ylmethyl)-4,7,10,13-tetraoxa-1-azacyclopentadecane) (R) in an aqueous medium to obtain a gel; and hydrothermally treating the gel at 80-140[deg] C under an autogenous reaction pressure for 1-50 days to obtain crystallization of the EMC-1 zeolite.
