  • Patent number: 5102644
    Abstract: A method of producing zeolites particularly ZSM-5 and ZSM-11 by strictly controlling the composition of the forming bath such that no organic is required. In a preferred embodiment the forming bath can contain seeds, lower aliphatic alcohols and/or ammonium hydroxide. The as-crystallized product has no organic in its pore structures and has a relatively low silica to alumina ratio.

  • Patent number: 4994251
    Abstract: As synthesized by previous methods, ZSM-5 or ZSM-11 zeolites are crystallized in the presence of substantial amounts of a nitrogen-containing compound. When synthesized in this way, they contain an organic ammonium cation as well as a metal cation such as sodium. To obtain a more active form, the sodium ion must be exchanged out. Such exchange, especially with ZSM-5 and ZSM-11, is difficult unless there is calcination of the zeolite to remove the obstructing organo compounds. By making these zeolites in the presence of (1) seeds of the desired zeolite, (2) mixtures of them with ammonium hydroxide and/or alcohol, (3) the alcohol per se or (4) mixtures of the alcohol with ammonium hydroxide, a product substantially deficient in organic ammonium cation is obtained. These products can be exchanged directly without any calcination.

  • Patent number: 4191638
    Abstract: Crystalline aluminosilicate zeolites are mixed with conventional reforming catalysts to produce new catalytic compositions with high catalytic activity and selectivity and excellent aging characteristics. These new catalytic compositions may be utilized alone or in conjunction with conventional reforming catalysts. The acidic activity of the total catalyst system is controlled within defined limits. When so controlled the utility of these catalyst systems in reforming hydrocarbon mixtures is to reduce the C.sub.1 and C.sub.2 concentrations in reformer gas product, while increasing the C.sub.3 and C.sub.4 concentrations and maintaining high liquid yield at high octane numbers.

  • Patent number: 4151189
    Abstract: A method is disclosed for synthesizing a crystalline aluminosilicate zeolite containing an organic nitrogen cation in the presence of a primary monoalkylamine having 2 to 9 carbon atoms in the alkyl portion. The method produces a zeolite having a very low percentage, i.e. less than about 0.14 weight percent, generally less than about 0.1 weight percent of alkali metal, e.g. sodium, in the as-synthesized form. The product can be used directly as a catalyst without intermediate precalcination and cation exchange. This is not possible with zeolites such as those of the ZSM-5 type synthesized by the methods of the art.
