Translation of "Thermal desorption" in German

Advantageously, the outlet of the thermal desorption device is connected to the mixing device.

Thermal desorption of the tubes was achieved using a Perkin Elmer ATD50 complete with cold trap.

Within the scope of the invention this is referred to as thermal desorption of the nitrogen oxides.

Solids can easily be analyzed by applying thermal desorption.

Subsequently the sample will automatically be introduced by means of thermal desorption technique.

Conceptual formulation such as material sample analysis (VOC-value, Fogging) using thermal desorption belong to our spectrum as well.

Preferably, the surface of the active semiconductor region is cleaned after the etching, by thermal desorption under vacuum.

In addition, during the storage phase, undesired nitrogen oxide emissions are observed during brief temperature increases as a result of thermal desorption of nitrogen oxides.

The packaged rod was subsequently transported to the oven in order to conduct the inventive thermal desorption.

Thermal desorption spectroscopy (TDS), also known as temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased.

The thermal desorption can be performed by raising the temperature to a range between ebullition and the degradation temperature of the compounds to be desorbed.

If the molecular sieve particles still contain small amounts of B compounds, a thermal desorption is recommended.

A forced, thermal desorption of the nitrogen oxides at exhaust gas temperatures above about 400° C. is undesirable, since sufficient hydrocarbons would then no longer be available for the reduction.

This invention pertains to a method to separate fluid mixtures consisting of at least two components, the fluid mixture being separated through contact with a selectively adsorbing/permeating membrane in conjunction with a porous transport matrix utilizing basic kinetic concentration effects in combination with thermal desorption of the sorbates.

When using stone coal pellets as adsorption media it can however be expedient to return the spent adsorption medium into the flue gas treatment process after treatment in a thermal regeneration apparatus (desorption apparatus) and, optionally after replacement of losses, reuse it for the flue gas scrubbing process.

The desorption processes which occur here are predominantly displacement desorption (as a result of CO 2, for example) and thermal desorption at temperatures of the reformate gas below 100° C.

Process according to claim 18, wherein for the purpose of discharging the substance to be detected, a release of the substance to be detected by means of chemical solvation or thermal desorption is carried out.

The fluid mixture is applied to the membranized lamellar surfaces from both sides, so that the permeating components can be removed subsequently from channels 3 of the central plate 1 following thermal desorption.

Analysis was by automatic thermal desorption and cold trap, the total sample being transferred to a CP Wax57CB capillary column 25 m long operated isothermally at 80°C with flame ionisation detection.

In this embodiment, the electrically insulating layer 26 on collector electrode 20 b consists of a 4×4 cm 2 silicon wafer, which is removed and undergoes thermal desorption after a certain period.

The dry processes operate above the dew point of the waste gases, but in case the adsorbent is recycled, they require either thermal desorption or, after extraction with a liquid extraction agent, drying.

Method according to claim 11, characterized in that the measurement chamber (3) and/or the hollow conducting element (4) is/are preconditioned with UV radiation, thermal desorption or by purging of reactive gases.

To prevent emissions of NH 3 to the surroundings, for example due to thermal desorption or loading-related slip, a further oxidation catalytic converter, not separately illustrated, may be provided as a so-called blocking catalytic converter downstream from the SCR catalytic converter unit 36 .

In the exhaust gas posttreatment device known from the prior art, an ammonia storage substance, or a mixture of various ammonia storage substances, is present in the storage container, and from these substances, ammonia is released by thermal desorption or thermolysis, or in other words by the effect of temperature.

Further, it is avoided by the inhibition of a NO x adsorption at low temperatures according to the invention that a formation of nitric acid and/or nitrous acid takes place in the SCR catalytic converter, which can effect a damage of the SCR catalytic converter or of parts of the exhaust gas purification system on the one hand, and can appear by means of an emission of undesired and highly toxic nitrous gases with a thermal desorption on the other hand.
