摘要： A catalyst is provided which contains 1 to 99 wt. % of a zeolite related to faujasite and having a hexagonally symmetrical structure and an Si:Al ratio between 3 and 30. The compensation cations of this zeolite consist partly or wholly of cations of one or more elements chosen from H, B, Al, Ga, In, rare earth metals and transition metals. The catalyst can also contain up to 15%, referred to the total weight of the binder and zeolite, of a catalytically active metal of the noble, non-noble transition or other type which is not already present in the compensation cations of the zeolite. The catalyst can be used in acid catalysis reactions carried out on hydrocarbon feedstock, in particular in fluidized bed catalytic cracking.

摘要： A process is provided for dealuminization of zeolites having large pores, the diameter of the aperture of the pores being greater than or equal to about 0.7 nm and the silica/alumina ratio greater than or equal to about 6. The process comprises acid leaching of the raw zeolite containing the structuring agent.The dealuminized zeolites obtained are useful as catalysts for the transformation of hydrocarbons and as selective organophilic adsorbents.

摘要： An aluminosilicate gel containing an ST structuring agent whose composition is suitable for crystallization into a zeolite of the faujasite structural family is prepared. The gel then undergoes crystallization in order to form a zeolite precursor which consists of the zeolite containing the ST structuring agent in its cavities and channels, the zeolite being produced through the calcination of the precursor. The ST structuring agent consists of at least one compound from the alkylene polyoxides of formula (1) ##STR1## in which R and R', identical or different, each represents H or an alkyl radical in C.sub.1 to C.sub.4, X designates H or OH, m is equal to 2 or 3 and can differ from one pattern to another, and n is a number from 1 to 12. The zeolites thus obtained have a Si:Al ratio which is greater than 1 and which can go beyond 3, and show a cubic symmetry. The zeolites can be used, directly or after cation exchange, as adsorbants or as catalyst constituents.

摘要： A process is provided for the preparation of zeolites belonging to the faujasite structural class and exhibiting a Si:Al ratio higher than 1 in which a reaction mixture is first produced which has a pH higher than 10 and contains water, a source of tetravalent silicon, a source of trivalent aluminum, a source of hydroxide ions in the form of a strong inorganic or orgnaic base and a structuring agent ST so as to produce an aluminosilicate gel having the desired composition to permit its crystallization into a compound of the faujasite structural class. The gel obtained is kept at a temperature, pressure and for a sufficient period to effect the crystallization of the gel into a precursor of the zeolite consisting of the zeolite trapping the structuring agent ST in its cavities and the precursor is then subjected to a calcination to destroy the structuring agent and to produce the zeolite. The structuring agent ST consists of at least one compound belonging to the group formed by the carbon-containing macrorings and macropolyrings which contain in the rings, heteroatoms chosen from oxygen, nitrogen, silicon and sulphur, and which contain 10 to 24 atoms per ring. Precursors of the zeolites are also provided.
