Abstract:
The present invention relates to a process for the preparation of a silicate compound, comprising (1) providing at least one layered silicate; and (2) mixing said layered silicate with water and at least one silicon containing compound according to formula R 4-m Si[-(SiR 2 ) n -R] m wherein at least one residue R is a leaving group and none of the residues R contains Si; m is 0, 1, 2, 3, or 4; and n is an integer greater than or equal to 0.
Abstract:
The invention relates to the use of a porous metal-organic framework material containing at least one at least bidentate organic compound bound coordinatively to at least one metal ion, said compound being used as a drying agent for reducing or for removing water from an organic liquid.
Abstract:
The invention relates to a method for producing crystalline solid matter comprising at least one zeolitic material. The solid matter is crystallised from at least one precursor compound. The reaction yield of the crystallisation is directly conveyed to a drying stage.
Abstract:
The invention relates to a method for the integrated production of aromatics and ammonia by reacting a gaseous stream A containing at least one C1 to C6 aliphatic compound and nitrogen in the presence of at least one catalyst. In one reaction, the C1 to C6 aliphatic compound is non-oxidatively converted into aromatics and the hydrogen released in said process is converted in a further reaction into ammonia.
Abstract:
The present invention relates to a method for producing a porous organometallic framework material by reacting at least one metal compound, the metal being Be, Mg, Ca, Sr, Ba, AI, Ga or In, with at least one at least bidentate organic compound. The invention also relates to the use of such porous organometallic framework materials.
Abstract:
The present invention relates to a porous metal organic framework material formed of Mg2+ ions which is coordinatively bonded by 5-tert.-butylisophthalate ions, during formation of a framework structure. The invention also relates to methods for the production and application thereof, for example, for storage, separation, or the controlled release of a substance such as a gas or gas mixture.
Abstract:
The invention relates to a pressurised gas container with a minimum volume of 1 m3 and a maximum filling pressure for filling with, storage and dispensing of a fuel which is gaseous under the storage conditions, the combustion of which can be used to propel a vehicle, characterised in that the pressurised gas container has a filter through which the fuel can flow at least on filling and dispensing, the filter being suitable for removal of possible contaminants in the fuel from the flow, said contaminants being able to reduce the storage capacity with regard to the fuel gas of an adsorbent used for storage of the fuel gas. The invention further relates to the use for such a pressurised gas container for filling a further pressurised gas container, the further pressurised gas container being arranged in or on a vehicle and containing an adsorbent for storage of the fuel gas.
Abstract:
The present invention relates to methods of removing carbon dioxide and optionally water from respiration air in closed or partially closed systems by means of a porous metal organic framework, systems of this type having at least one breathing apparatus and also their use and methods of regenerating the porous metal organic framework.
