Method of reducing NOx in diesel engine exhaust

A sidestream located hyper-plasma reactor having an axially discrete pattern of alternating regions of active and passive electric field along the axial direction. The hyper-plasma reactor has great efficacy in terms of ultra low power consumption and copious production of NO_x converting aldehydes in the absence of NO by applying plasma power only to an air and hydrocarbon mix sidestream gas flow. Only a small fraction (1% to 2%) of plasma power is required as compared to that for a conventional plasma reactor to treat the full exhaust gas stream. The hyper-plasma reactor produces ozone which reacts subsequently with hydrocarbons to produce aldehydes ("ozonolysis"). The sidestream location of the hyper-plasma reactor allows for the full exhaust stream to bypass it, without significantly affecting the overall NO_x conversion performance in the catalytic converter.

Apparatus and method for regenerating catalyst for purifying exhaust gas

A regeneration apparatus comprises a heater 2 which heats a catalyst 1 at the time of stopping fuel supply to an engine, a pump 4 which supplies an oxidizing gas or a reducing gas to the heated catalyst 1 and a switching valve 3. In the oxidizing step, catalytic poisons, for example hydrocarbon, which are absorbed on a noble metal are oxidized and removed. The particles of the noble metal become oxidized particles as pure oxide and the like. After the oxidizing step, the reducing step is carried out. In the reducing step, particles of the noble metal are reduced and re-dispersed on the support simultaneously and as a result, the particles of the noble metal become fine. Thus, a deteriorated catalyst can be regenerated without interrupting the use of catalyst and also without deteriorating the drivability.

Nitrogen oxide generating procedure for producing ammonia as reducing agent in catalytic converter uses plasma reactor to assist process

The procedure for producing nitrogen oxides (NOx) and ammonia (NH3) employs a plasma assisted process to reduce the NOx to NH3 by the addition of a gas containing H2. The NH3 thus produced is used as a reducing agent in a selective catalytic reduction (SCR) unit to clean motor vehicle i.c. engine exhaust gases. The operational gas, which has a flow mass that is low in relation to the flow mass of the exhaust gases, is heated in a gas discharge to temperatures above 2000 deg K, and preferably above 2800 deg K so that the molecular nitrogen and oxygen are excited electronically and dissociated and/or ionized by a non-thermal impulse process or plasma shock with high-energy electrons. The reaction of the molecules, molecule fractions and electronically excited ions produced nitrogen oxides, especially NO, while the concentration of NOx produced by the plasma is in the region of 2 - 5 per cent.
