A process for preparing methanol by a methanol synthesis reaction of carbon dioxide with hydrogen may involve a distillation step and a condensation step following the synthesis of a crude methanol. A volatile component and water may be separated off from a methanol-containing product stream, and a gas stream containing a volatile component that has been separated off may be discharged at least partially as offgas. At least part of the gas stream that has been separated off may be recirculated into the methanol synthesis reaction. A plant for preparing methanol can store or utilize electric power generated from renewable energy sources and provide facilities for discharging the offgas stream, which can be purified by catalytic after-combustion. Alternatively, the plant can be configured without discharge of an offgas substream, or the offgas streams are so small that they can be released without treatment into the environment at a suitable position.

Method and system for the production of methanol

A catalyst-coated support including a sheetlike support, a primer layer applied thereto and composed of nanoparticles composed of silicon oxide-comprising material, and at least one catalyst layer applied to the primer layer. The layers applied are notable for a particularly good adhesive bond strength and can be used particularly efficiently in heterogeneously catalyzed gas phase reactions, especially in microreactors.

Catalyst-coated support, method for the production thereof, a reactor equipped therewith, and use thereof

A modular element having a high-temperature stable main body, including at least one metallic or ceramic plate, which has at least one through-going aperture for the insertion of a ceramic capillary membrane and at least one potting in the form of a sufficiently gas-tight and high-temperature stable joint between the metallic or ceramic plate and the ceramic capillary membrane. The through-going aperture of the metallic or ceramic plate having an extension for accommodating the sufficiently gas-tight and high-temperature stable joint on at least one side of the metallic or ceramic plate.

Method for potting ceramic capillary membranes

A porously coated, densely sintered ceramic membrane, which can be produced from a green membrane and subsequent sintering. The membrane is coated with ceramic material, which contains noble metals, which can be produced by application and subsequent thermal treatment. The noble metals are contained at a concentration of 2.5 to 5 mass percent.

Ceramic membrane having a catalytic membrane-material coating

A modular construction micro-reactor with parallel microchannels on fluid guide plates for chemical reactions, but not for evaporation purposes is known. A modular construction falling film evaporator is disclosed, comprising a stack of alternate gap-like evaporation chambers and sheet-like evaporator modules with an assembly of parallel microchannels, whereby the evaporation chambers are open above and/or below across the whole width of the module and the stack is arranged in a container. The falling film evaporator is used in a method for obtaining a gaseous phase from a liquid medium on a technical scale and is suitable for the concentration of thermolabile solutions and rapidly adjustable production of a gas stream.

Method for obtaining a gaseous phase from a liquid medium and device for carrying out the same

The present invention discloses a microreactor for performing heterogeneous catalytic reactions, being of plate or stack construction for industrial use, with provision made for chambers between the plates for the chemical reaction and for the heat removal. Inside the reaction chambers, catalyst material is applied to the internal walls or filled into recesses, and in all chambers there are spacers. In particular the slot-shaped reaction chambers have channels with a hydraulic diameter smaller than 1500 &#x3bc;m and a ratio of free slot width to free slot height in the range of 10 to 450.
