ABSTRACT IMPROVED ZEOLITE L A zeolite related to zeolite L and having a charac- teristic cylindrical morphology may be prepared from a crystallization gel comprising (in mole ratios of oxides): K2O/SiO2 0.22 - 0.36 H2O/K2O 25 - 90 SiO2/Al2O3 6 - 15 and preferably with the mole ratio H2O/K2O+Al2O3+SiO2 being at least 8. The cylindrical Zeolite L may be used as a catalyst base in aromatization of acyclic hydrocarbons with high benzene yields being sustained over commercially feasible periods.
