ABSTRACT ZEOLITE L PREPARATION Zeolite L containing caesium having enhanced catalytic properties is prepared by a process in which said zeolite L is crystallised from a synthesis mixture with a molar composition (expressed as oxides) of: K2O/SiO2 0.22 to 0.30 K2O/Cs2O 5 to 12 H2O/K2O 50 to 90 and SiO2/Al2O3 6.0 to 7.0 and containing 0.5 to 20 ppm (by weight) of divalent metal cations, e.g. Mg ions. The zeolite L can form part of a dehydrocyclisation and/or isomerisation catalyst.
