N2 - Zeolite synthesis was performed from low water containing initial gels. The batch composition was: aM2O–bNa2O–bAl2O3–150SiO2–2bTAABr–490H2O with M=Li, Na, K; TAA is tetramethyl, tetraethyl and tetrabutyl-ammonium; 2.25⩽a⩽8.82 and 1.87⩽b⩽30. Self-bonded pellets of high mechanical resistance of mordenite and ZSM-11 were obtained from two systems: the first one did not contain any organic cations, while the second one was made in presence of tetrabutylammonium bromide. The other systems led either to nonpelleted mordenite, ZSM-5 or sodalite.
