摘要:
A catalytic converter for the treatment of combustion exhaust gases includes a first large surface, which is exposed to the exhaust gas to be purified and which has a layer of a catalytically active material suitable for converting gas components, and a planar first electrode which is in physical contact with the layer made of a catalytically active material suitable for converting gas components, and which is able to receive an electric pumping voltage.
摘要:
A water treatment plant is described having a filter element situated between a water inlet line for raw water and a water discharge line for purified water, having a pump unit for pumping, in particular pressing and/or drawing, the water through the filter element, having at least one purifying unit for the filter element, having sensors for detecting water properties, and having a control unit connected to the sensors for activating the at least one purifying unit. It is provided that the control unit includes a computer program for adaptively activating the at least one purifying unit or adaptively changing the volume flow of the pump unit. Furthermore, a method for operating a water treatment plant and a computer program is also described.
摘要:
A filter for removing particles from a gas stream has a filter pad with a coating which contains at least one of the following substances: (a) at least one aluminum oxide selected from alpha-, gamma-, delta- and theta-aluminum oxide, (b) hydrous aluminum oxide which is doped with silicon dioxide, at least one oxide of a metal of the 3rd to 5th B group, at least one oxide of a lanthanoid including lanthanum or a mixture of one or more of these oxides, (c) silicon dioxide or silicon-rich zeolite or (d) titanium dioxide which is doped with at least one oxide of a metal of the 3rd to 6th B group or an oxide of a lanthanoid including lanthanum, (e) a mixture of zirconium dioxide with at least one oxide of a metal of the 3rd to 5th B group, at least one oxide of a lanthanoid including lanthanum or a mixture of one or more of these oxides.
摘要:
A fluid filter has a plurality of inlet channels, a plurality of outlet channels, and filter walls separating the inlet channels from the outlet channels. The inlet channels are parallel to the outlet channels, and the filter walls have a plurality of pores through which the inlet channels are connected to the outlet channels. A cross-sectional area of all inlet channels is larger than a cross-sectional area of all outlet channels, and a value of diameters of the pores of the filter walls calculated by mercury porosimetry being a median value d50, being between 0.01 μm and 0.5 μm.
摘要:
In a method for obtaining dinitrogen monoxide by microbiological or enzymatic processes from nitrogen-containing substances, the microorganisms, bacteria, archaea, eukaryotes, fungi, parasites, phages, cells, cell fractions or membrane fractions, and/or enzymes, and/or a combination thereof to be used in this context are selected, or manipulated or partly or entirely reversibly and/or irreversibly inhibited by suitable actions, or the corresponding microbiological or enzymatic processes are controlled, for example, by way of suitable process conditions, so that, in part or entirely, dinitrogen monoxide (N2O) is formed from the nitrogen-containing compounds of the nitrogen-containing substances.
