ABSTRACT ZEOLITE L PREPARATION Zeolite L containing caesium 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 0.15 to 0.40 K2O/Cs2O 3 to 10 H2O/K2O 40 to 100 and SiO2/Al2O3 7 to 13 and containing 0.5 to 15 ppm (by weight) of divalent metal carbons, e.g. Mg ions. The zeolite L can form part of a dehydrocyclisation and/or isomerisation catalyst.
