The present invention relates to a reactor R with apparatus D, the latter comprising a gas- and/or liquid-permeable tray B, in the edge region of which there is disposed a lateral boundary W which fully encloses the tray B and forms a volume V comprising catalytic and/or noncatalytic shaped bodies (F), wherein there is at least one braid made of precious metal and/or base metal on the upstream side opposite the tray B, and the catalytic and/or noncatalytic shaped bodies (F) are selected from (i) shaped bodies (F) in the form of straight prisms, the footprint of which is selected from triangle, rectangle, hexagon or fragments of these polygons, and (ii) a combination of the shaped bodies (F) with shaped bodies (F) that are smaller than the shaped bodies (F), wherein groups of m to n shaped bodies (F), m and n being an integer from 3 to 30 with n&#x3e;m, are framed in a metal cassette open in the upstream direction and closed in the downstream direction by a gas-permeable tray, in a virtually seamless manner with side face to side face and with their longitudinal axis aligned in vertical direction, virtually completely covering the cross section of the tray, to form modules (M), and the modules (M), optionally with cooperation of a joint filler material, with vertical alignment of the longitudinal axis of the shaped bodies (F), are joined to one another virtually seamlessly in a mosaic-like manner.

Modular catalyst monoliths

The invention relates to a reactor for carrying out heterogeneously catalyzed gas-phase reactions, having an internal element () or a plurality of internal elements () which are arranged in succession in the flow direction of the gas mixture of the heterogeneously catalyzed gas-phase reaction through the reactor (), where the internal elements extend over the entire reactor cross section, wherein the one or more internal elements () is/are at least partly made of a fiber composite ceramic material.

Reactor for carrying out heterogeneously catalysed gas phase reactions, and use of the reactor

A device D accommodated in a reactor R and containing a gas- and/or liquid-permeable bottom B, in the peripheral region of which is arranged a lateral boundary W which completely surrounds the bottom B and forms a volume V which is partially or completely filled with catalytic and/or non-catalytic moldings, there optionally being located on the side facing the bottom B in the upstream direction at least one noble metal and/or non-noble metal fabric, wherein a thermal insulation layer S is located on at least part of the surface of the inner side of the lateral boundary W of the device D, the material for the thermal insulation layer S being selected from the group consisting of ceramic material, microporous material and silicate fibers.

Basket-like device having wall insulation

The invention relates to a tray for a mass transfer column, having gas passage openings distributed over the tray (), and having at least one baffle () for flow diversion of liquid flowing on the tray, it being possible for the tray () to be fed with a liquid via at least one entry (). The tray has at least one entry (), at least one separating weir (), which separates the inflowing liquid into two streams, and at least two exits (), or has at least two entries () and at least one exit () for the liquid, each stream flowing along a flow path () to an exit (). The invention further relates to a mass transfer column comprising the tray, and to a use of tray and mass transfer column.

Base for a mass transfer column

The invention relates to a process for removing small amounts of water and possible further constituents from alkali metal amalgam, wherein the alkali metal amalgam is brought into contact with an element which is insoluble in mercury and catalyzes the reaction of water with the alkali metal amalgam and the possible further constituents to form hydroxides and hydrogen.

Process for removing water from alkali metal amalgam

An electrolysis device producing alkali metals from a liquid alkali metal heavy metal alloy, including at least two connected tubes forming an electrolysis unit. Two solid electrolyte tubes are arranged concentrically in each tube and oriented with openings towards one end of each tube such that a first annular gap for guiding a liquid alkali metal forming an anode is located between the inside of the tube and the outside of the solid electrolyte tubes. An alloy inlet and outlet for the liquid alkali metal in each of the tubes leads into the first annular gap of a tube. An inner chamber sealed off from the alloy inlet, first annular gap, and alloy outlet in each solid electrolyte tube receives liquid alkali metal that can be used as a cathode connected to the alkali metal outlet. Two respective closure devices are arranged at the two ends of each tube.

Electrolysis device for the production of alkali metal

Mercury is removed from solutions contaminated with mercury, the solution contaminated with mercury being introduced into a distillation column above the column bottom, solvent being distilled off and solution depleted in mercury being stripped off at the column bottom.

Process for the removal of mercury from solutions contaminated with mercury

Mercury is removed from solutions contaminated with mercury by filtration through a carbon filter consisting of electrode graphite.

Method for producing alkali methylates

Alkali metal alkoxides are prepared by reacting alkali metal amalgam with alcohol in the presence of a catalyst comprising iron having a carbon content of at least 0.3% by weight.

Catalytic preparation of alkali metal alkoxides

Method for producing highly pure lithium salts

Highly pure LiBF is prepared by preparing a solution of BF etherate in diethyl ether, suspending LiF in this solution, reacting to give solid LiBF , and then separating off the solid LiBF formed. The LiBF prepared is used for producing lithium ion batteries.

Method for producing highly pure LiBF4

The invention relates to a process for preparing alkali metal alkoxides by reacting alkali metals with alcohols in the presence of a catalyst, preferably a transition metal salt and especially iron(III) chloride.

Method for producing alkali metal alcoholates

In the process for the preparation of vinylsilanes by reacting acetylenic hydrocarbons with silanes which have at least one silicon-bonded hydrogen atom in the liquid phase in the presence of a catalyst, the silane is added to the liquid phase. In particular, the reaction is carried out at superatmospheric pressure, and the spent acetylenic hydrocarbon is replenished during the reaction while maintaining a pressure which is constant during the entire reaction.
