摘要： Zeolite L with cylindrical morphology and with flat basal planes, and reduced crystallite size is prepared in a synthesis modified by the addition of small amounts of additional metal such as magnesium, calcium, barium, cobalt, zinc, chromium, manganese or nickel. The addition of these metals also suppresses unwanted zeolite W formation even when the synthesis would otherwise form this zeolite.
Use in catalytic compositions, especially in the dehydrocyclisation and/or isomerisation of aliphatic hydrocarbons.-

摘要： Binder-free shaped particles of caesium-containing zeolite L-potassium form (zeolite KL) are made by a process which comprises forming a mixture of shaped particles of silica-bound zeolite KL with an aqueous caesium-containing potassium aluminate solution and obtaining the desired binder-free shaped particles by crystallisation of the mixture. The shaped particles thus obtained can form part of a dehydrocyclisation and/or isomerisation catalyst.

摘要： Binderless particles of zeolite L of very high mechanical strength are prepared by a process which comprises forming a mixture by reacting substantially binderless particles of zeolite L, preferably as shaped particles such as extrudates, with an aqueous alkaline solution containing sources of alkali metal, at least 50 mole % of which is potassium, and aluminium to obtain the desired particles of very high mechanical strength. The zeolite L thus obtained can form part of a dehydrocyclisation and/or isomerisation catalyst.

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。
