Übersetzung für "Katalytische nachverbrennung" in Englisch

Advantageously, catalytic or thermal afterburning is used in the process according to the invention.

The air emissions from distillation are completely neutralised by means of catalytic afterburning.

Catalytic oxidiser systems are an alternative to TOS units.

Compared with purely thermal oxidation, catalytic combustion is an economically attractive variation.

The production of the main toxic components is quantitatively varied individually by regulation of separate combustion chambers. The toxic components from exhaust gas pipes of the respective combustion chambers are combined, in such a manner that in accordance with the proportions of the main toxic components, the composition of the exhaust gas mixture enables complete catalytic after-combustion conversion thereof in a known manner.

Moreover, the use of silicone-based products in aqueous coating systems often provokes problems of interlayer adhesion; when used in dipping tanks, it is difficult to avoid the occurrence of craters over a prolonged period; and, in application processes that are followed by catalytic post-combustion, the service life of the catalysts is reduced.

A process according to claim 1, wherein the combustion zone is either a catalytic combustion zone or thermal combustion zone.

The exhaust gas catalytic converter is a component integrated in the exhaust gas system of e.g. a motor vehicle and in which catalytic afterburning takes place.

In order to avoid any danger of explosion also occuring during the production of these harmful substances, particularly heating plants and automobiles without catalytic post-combustion have to be operated with a certain amount of excess air.

The KANTOS dryer has an integrated catalytic incinerator which heats the offset dryer via excess heat coming from the oxidation of the solvents from the dried offset paint.

Towards this end, it is a known practice to employ so-called FLOX burners, that is to say, burners with flameless oxidation, or catalytic after-burning.

It can therefore be released into the atmosphere without great losses of methane and without major impairment of the environment, without any need for further treatment of the gas by a catalytic or thermal afterburn or utilization in a combined heat and power plant.

In a further embodiment of the invention, the content of aromatic hydrocarbon solvent in the cycle gas stream a2 is limited to less than 1% by volume by a thermal or catalytic post combustion of the aromatic hydrocarbon solvent.

Suitable catalysts for a catalytic post combustion have been described many times in the literature; see, for example, Prasad et al., Catel.

It can therefore be released into the atmosphere without any great losses of methane and without any great impairment of the environment, without any need for further treatment of the gas by a catalytic postcombustion or utilization in a combined heat and power plant.

The objective of this project was the development of ceramic catalysers for the elimination of organic compounds from industrial offgases through catalytic post-combustion and catalytically supported combustion.

In the applications with problem components studied over extended periods with pilot systems, such as foundries, it was found that using catalytic post-combustion does not make sense, as even standard platinum catalysts do not reach combustion temperatures of 330 °C or below constantly.

From the historical point of the development of incineration systems the Catalytic Oxidation (CatOx) followed the classic thermal oxidizer (TO).

The objective of this project was to develop perovskite-type catalyst material for catalytic combustion and catalytic-supported combustion of polluting exhaust gases.

Novus cooperates with Formia, the Finnish technology leader for energy efficient catalytic oxidation.

The purge gas stream can be subjected to a thermal or catalytic post combustion.

The secondary treatment can be effected thermally, for example, by secondary combustion, catalytically or else by means of an adsorption filter.

Depending upon its composition, the waste gas may be either directly vented to the atmosphere or delivered to a catalytic post-combustion stage in which residual impurities are removed by oxidation.

The waste gas from the catalytic post-combustion contains, in addition to the gas components of the cooling gas for the desublimation, carbon dioxide and water (steam) from the main reaction in reactor (3) and the post-combustion of the byproducts in reactor (11).

The method of the present invention, on the other hand, subjects the waste gas from the known desublimation method to a cooling gas from a known catalytic post-combustion.

In the present invention, the gas obtained from the catalytic post-combustion is divided. One portion is led back to the reactor for the production of PMDA, while the other portion is released into the atmosphere.

Instead of cooling the entire quantity of waste gas from the catalytic post-combustion, it is also possible to cool only the waste gas which is drained off and to lead the circulating gas through line (1) into reactor (3) at the temperature at which it emerges from post-combustion reactor (11).

The heat produced by the catalytic afterburning of the exhaust gases can be effectively transferred to the two sets of educt flow tubes 20 b and 21 b which are completely surrounded by catalyst material 26 .

It is also possible to supply the absorption unit 15 with the exhaust gas from the catalytic afterburning together with the exhaust gas from the fuel cell.

The waste gas stream is minimal with catalytic afterburning since the combustion temperature is lower than in thermal afterburning and thus less fuel is necessary for afterburning.
