    Abstract: O.Z.0050/034495 of the disclosure: A process for the preparation of zeolites of the ZSM-5 structural type from a mixture of SiO2 and Al(OH)3 by hydrothermal crystallization in an aqueous amine solution, in the absence of alkali, at from 100 to 200.degree.C, wherein the crystallization is carried out in the presence of a triamine, tetraamine and/or higher amine and the reaction mixture is formulated to have an SiO2/Al2O3 molar ratio defined by an equation which involves the chain length and number of amine groups of the amine employed, as well as to have certain molar ratios of H2O/amine and amine/Al2O3, and the use of these zeolites as catalysts for the conversion of alcohols and/or dialkyl ethers to olefins and/or aromatics.

    Abstract: The present invention is concerned with a crystalline SiO2-modification, which is characterized by an X-ray diffraction diagram having certain diffraction lines, and with a process for the preparation of this crystalline SiO2-modifi-cation. This process is achieved by heating a mixture of a reactive amorphous SiO2 in an aqueous solution of hexamethylenediamine at a temperature of from 100.degree. to 200.degree.C for from 0.5 to 50 days, to effect crystallization of the SiO2 to the crystalline SiO2-modification. Sodium ions, phosphate ions and /or sulfate ions may be added for the crystallization. With the novel process it is possible to prepare new , high-grade absorbents which have a definite pore size and are therefore particularly suitable for the selective separation of organic components from solvents.

    Abstract: A process for the manufacture of a bifunctional catalyst for the conversion of hydrocarbons, which contains a crystalline aluminosilicate of the type of the Y-zeolites as the acidic component and a noble metal as the hydrogenation component. The process constitutes a technologically simple way of manufacturing bifunctional zeolite catalysts which have at least the same activity and the same life as the catalysts manufactured by conventional methods, coupled with great heat stability and exhibit activity in the presence of H2O, H2S and NH3 at relatively high temperatures.
