摘要： 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 cations, e.g. Mg ions. The zeolite L can form part of a dehydrocyclisation and/or isomerisation catalyst.摘要翻译： 含沸石L的铯是用一种方法制备的，其中所说的沸石L由摩尔组成（用氧化物表示）：K 2 O / SiO 2 0.15-0.40 K 2 O / Cs 2 O 3 -10H 2 O / K 2 O 40-100的合成混合物结晶， SiO 2 / Al 2 O 3 7-13，含有0.5-15ppm（按重量计）的二价金属阳离子， 镁离子。 沸石L可以形成脱氢环化和/或异构化催化剂的一部分。

摘要： Binderless zeolite L particles are prepared by a method in which particles are formed from silica and from 0 to 95 wt% preformed zeolite L crystallites, and the particles are thereafter reacted with an alkaline solution comprising a source of alumina to convert the silica binder to zeolite L. These particles may comprise cylindrical zeolite L crystallites with a mean diameter of at least 0.05 micron in a zeolite L matrix and may be used as catalyst. Also acyclic hydrocarbons are dehydrocyclized and/or isomerized by contacting them at a temperature of from 370°C to 600°C with this catalyst incorporating at least one Group VIII metal having dehydrogenating activity to convert at least part of the acyclic hydrocarbons into aromatic hydrocarbons.
