Definitions
- the invention relates to a method for exhaust aftertreatment having the features of the preamble of claim 1, as well as an exhaust aftertreatment device having the features of the preamble of claim 2.
- RTO regenerative thermal oxidation
- unburned hydrocarbons and other oxidizable exhaust gas constituents are thermally oxidized.
- the regenerative thermal oxidation of the exhaust gas is first passed through a, usually made of ceramic bulk material or honeycomb bodies, heat storage to finally reach the reaction chamber.
- the exhaust gas can be further heated by additional heaters until a thermal oxidation of the undesirable exhaust gas constituents can take place. Subsequently, the exhaust gas flows through another heat storage to the exhaust and is released into the environment.
- the flow direction is changed alternately, whereby the exhaust gas is preheated before reaching the reaction chamber, whereby an energy saving in the further heating of the exhaust gas sets.
- the additional heating can be set up by gas injection or burner (so-called support gas) or an additional electric heater.
- the reaction chamber usually has a free flow cross-section, whereby the residence time of the exhaust gas is increased in the reaction chamber and the oxidation can proceed in the form of a gas phase reaction.
- Particularly relevant among the species to be oxidized in the exhaust gas are carbon monoxide (CO) and methane (CH 4 ).
- CO carbon monoxide
- CH 4 methane
- Such a device is z. B. known under the brand name CL.AIR ® by GE Jenbacher.
- the CL.AIR ® thermal reactor is constructed as a regenerative heat exchanger and consists of two storage masses, a reaction chamber and a switching mechanism.
- the exhaust gas flows at a temperature of about 530 ° C from the engine via a switching mechanism in a first storage mass, where it is heated to about 800 ° C.
- the exhaust gas reacts with the existing oxygen, whereby carbon monoxide and unburned hydrocarbons are oxidized to carbon dioxide and water.
- the exhaust gas is again from heat and reaches at a temperature of 550 to 570 ° C, the switching mechanism, which it feeds the chimney or a downstream waste heat recovery.
- Regenerative thermal oxidation offers a robust process with which even large exhaust gas mass flows can be economically treated.
- Thermoreactors previously described are designed to oxidize both methane and carbon monoxide. This brings some disadvantages in operation.
- thermoreactor In order to reduce carbon monoxide, a relatively high temperature and a relatively long residence time are required in the thermoreactor.
- thermoreactor is catalytically oxidized, preferably catalytically oxidized in the thermoreactor, thus ensures that the thermoreactor must be designed for lower temperatures and a shorter residence time of the exhaust gas, and yet the carbon monoxide can be reduced to a satisfactory extent. It is thus provided according to the invention that methane is first reduced by thermal oxidation.
- the parameters in the thermoreactor are chosen to allow for partial oxidation of methane to produce carbon monoxide instead of being reduced as conventionally provided in thermoreactors.
- the resulting pretreated exhaust gas thus contains a larger amount of carbon monoxide than in the original exhaust gas while unburned hydrocarbons, especially methane, are already oxidized.
- a catalytic oxidizer This can be provided, for example, as an oxidation catalyst consisting of a catalyst support medium, as is known, for example, for exhaust aftertreatment from the automotive sector.
- the oxidation catalytic converter is set up by catalytic coating of volume sections of the thermal oxidation catalytic converter. This can be achieved, for example, by providing volume sections of the ceramic storage material present in the thermal oxidation catalyst with a catalytically active surface or introducing other catalytically active materials.
- An exhaust aftertreatment device thus contains an input for exhaust gas, a thermal reaction zone and at least one catalytic reaction zone, wherein the at least one catalytic reaction zone downstream of the thermal reaction zone in the flow direction of the exhaust gas through the exhaust gas aftertreatment device.
- the thermal reaction zone and the at least one catalytic reaction zone are arranged in a common housing.
- This can be realized, for example, by integrating a volume section with catalytically active material into the reaction zone of the thermoreactor.
- the catalytically active region is formed in the ceramic storage mass of the thermoreactor. This describes the case where a catalytically active region is formed by catalytic coating of part of the surface of the ceramic bulk material of the thermoreactor.
- the catalytic reaction zone of the thermal reaction zone is connected downstream of the exhaust gas aftertreatment device in a housing separate from the thermal reaction zone in the flow direction of the exhaust gas.
- This embodiment describes the case where the thermoreactor and the oxidation catalyst are realized as separate components.
- a thermoreactor is provided which corresponds in terms of its design to the prior art and downstream of which an oxidation catalytic converter is connected downstream.
- FIG. 1 shows a schematic representation of an internal combustion engine 1, which is connected via the exhaust manifold 2 with the exhaust gas aftertreatment device 3.
- the flow direction of the exhaust gas through the thermoreactor 11 can be changed.
- the flow direction of the exhaust gases can first be carried out alternately by the storage mass 5, the thermal reaction zone 7 and the storage mass 6.
- the exhaust gas flows first through storage mass 6, then through the thermal reaction zone 7 and finally through storage mass 5.
- the exhaust gas leaves the system via line 8 and becomes a chimney or a waste heat recovery (both not shown). fed.
- FIG. 1 shows a schematic representation of an internal combustion engine 1, which is connected via the exhaust manifold 2 with the exhaust gas aftertreatment device 3.
- the reaction chamber 7 facing volume sections 9 of the storage masses 5 and 6 provided with a catalytic coating or a catalytically active material.
- the control / regulating device 12 which on the one hand can receive signals from the internal combustion engine 1 and the exhaust gas aftertreatment device 3, on the other hand also commands Can send actuators of the exhaust aftertreatment device 3.
- the fuel line 13 via which the internal combustion engine 1 with fuel, such as propellant, is supplied.
- a branch can be provided, via which the thermoreactor 11, if necessary supporting gas can be supplied to the additional heating.
- FIG. 2 shows a schematic representation of an internal combustion engine 1 with an exhaust aftertreatment device 3 analog FIG. 1
- the exhaust aftertreatment device 3 from a thermoreactor 11, consisting of storage masses 5 and 6, and a thermal reaction zone 7 and a downstream of the thermoreactor provided in line 8 oxidation catalyst 10 is formed.
- the flow direction can be changed by the thermoreactor 11 alternately.
- the thermoreactor 11 has no catalytically coated volume sections in this embodiment.
- the pretreated in the thermoreactor 11 exhaust gas flows through the oxidation catalyst 10 and is directed from there to a chimney or exhaust gas heat recovery (both not shown).
- FIG. 3 shows a schematic representation of an internal combustion engine 1 with an exhaust aftertreatment device according to the prior art. Here, a thermoreactor without catalytically coated zones is formed.
