2.1. Zeolites are microporous crystalline aluminosilicates which are distinguished by a number of particular properties. They have a defined cavity system with orifices of 0.3 to 0.9 nm. They are cation exchangers. In the H form, they have high acidity in the solid state. The hydrophobic character c ...

The previously known processes for the preparation of zeolite-analogous gallosilicates require organic structure-directing or structure-stabilising compounds. In most cases those are amines which, apart from the cost factor, may constitute a not insignificant environmental risk. The object is to off ...

Tissler Arno Dr, Thome Roland Dr: Method for preparation of layered silicates of the magadiite type.. Vaw Ver Aluminium Werke, February 26, 1992: EP0472144-A2 (4 worldwide citation)

2.1 Magadiite is a rare natural mineral, an aluminium-free hydrated sodium silicate having a sheet structure of the composition Na2O.14SiO2.9H2O. The processes developed for the preparation of magadiite have long crystallisation times and hence low space-time yields. 2.2 It is intended to provide an ...

Tissler Arno Dr: Synthetic cristalline zeolite powder, its preparation and its use. Alsi Penta Zeolithe, December 2, 1998: EP0881193-A1 (3 worldwide citation)

Synthetic crystalline zeolite powder having a SiO2/Al2O3 ratio of at least 5 is produced by the hydrothermal reaction of a source for SiO2, Al2O3, alkali, water and optionally organic additive, converting into the activated state and thermally treating until the required catalytic-activity is reache ...

Thome Roland Dr, Tissler Arno Dr: Molded aluminosilicate catalyst and method for its preparation.. Vaw Ver Aluminium Werke, December 27, 1990: EP0403966-A1 (3 worldwide citation)

Disclosed is a molded aluminosilicate catalyst, including a zeolite powder and a SiO2-containing powder. The SiO2-containing powder includes SiO2 particles of from about 0.1 to about 5 microns in average diameter. The aluminosilicate catalyst includes from about 5 to about 70 percent by weight of th ...

Vaw Ver Aluminium Werke, Zentralinstitut Fuer Physikali, Akad Wissenschaften Ddr, Leuna Werke, January 9, 1991: EP0406872-A2 (3 worldwide citation)

2.1 Molecular sieves which belong to the aluminosilicates of the zeolite type have long been known. They are distinguished by the fact that their structure consists of AlO2- and SiO2 tetrahedra whose sequence in the lattice leads to a characteristic pore structure. These and other properties give so ...

The invention relates to a process for recycling packaging materials containing one or more synthetic polymers and/or metal and/or natural polymers, with dissolution of the synthetic polymer component in a solvent and recovery of soluble and insoluble packaging constituents. The object of the presen ...

Thome Roland Dr, Tissler Arno Dr: Method for the preparation of crystalline and zeolitic aluminosilicates.. Vaw Ver Aluminium Werke, December 19, 1990: EP0402801-A2 (2 worldwide citation)

Disclosed herein is a method of preparing crystalline, zeolitic aluminosilicates with Si02/Al2O3 ratios of 20 or more. The method provides a two-stage crystallization process which avoids the formation of secondary crystalline phases. The first stage is conducted at a temperature between 240 DEG C a ...
