A plasma assisted reactor for the removal of carbonaceous combustion products or for simultaneous removal of carbonaceous products and nitrogen oxides from the exhaust emissions from an internal combustion engine, wherein the reactor includes a gas permeable bed made at least primarily of active materials comprising perovskite or vanadate.

Plasma assisted reactor

A reactor chamber forms part of an exhaust system of an internal combustion engine. Within the chamber are electrodes between which there is disposed a bed of active material through which, in use, the exhaust gases pass. In the presence of an electrical discharge, driven by an electrical voltage applied across the electrodes, the active material has a catalytic action in the reduction of nitrogenous oxides in the exhaust and also acts to remove hydrocarbons from the exhaust gases.

Treatment of gaseous emissions

A reactor () particularly for the plasma treatment of internal combustion engine exhaust gases, in which a power supply () and a reactor bed () of the dielectric barrier discharge type are connected directly and enclosed in an earthed metal chamber () which both isolates the high voltage power supply and acts as a Faraday cage preventing the emission of electromagnetic radiation from the power supply or plasma.

Power supply for processing of gaseous media

A reactor for the plasma-assisted processing of a gaseous medium, including a pair of electrodes having facing surfaces the separation of which is substantially uniform, with a body of dielectric material positioned between them and defining a plurality of gas passages extending through the space between the electrodes.

Plasma-assisted processing of gaseous media

A power supply and control system for a motor vehicle incorporating a plasma-assisted reactor for treatment of exhaust emissions and including a power source for supplying first and second output voltages.

Vehicle power supply system

A reactor for the plasma-assisted processing of gaseous media comprising a reactor chamber including a gas permeable bed of active material, a power source for applying across the bed of active material a potential sufficient to establish a plasma in a gaseous medium flowing through the bed of active material and a chamber having an inlet stub and an outlet stub for constraining the gaseous medium to flow through the bed of active material, wherein the bed of active material comprises a matrix of beads of a dielectric material having an assembly of regular arrays of beads in each of which adjacent beads are connected to a high voltage input terminal or an electrical ground.

Reactor for plasma assisted gas processing

A reactor for the plasma processing of gaseous media, especially internal combustion engine exhaust, has a bed made of a body of ceramic material a series of gas permeable electrodes embedded within the bed. The electrodes are distributed to provide a predetermined electric field distribution within the bed.

Reactor for processing gaseous media

A reactor particularly for the plasma treatment of internal combustion engine exhaust gases, in which a power supply and reactor bed are connected directly and enclosed in an earthed metal chamber which both isolates the high voltage power supply and acts as a Faraday cage preventing the emission of electromagnetic radiation from the power supply or plasma.

Gas purification device

A reactor for the plasma processing of gaseous media, especially internal combustion engine exhaust, has a bed made of a body of ceramic material and electrodes. At least one electrode terminates within the bed at a distance from earthed supporting structure to avoid or reduce the risk of tracking or arcing between the electrode and the supporting structure.
