A catalytic reactor () comprises a plurality of sheets () defining flow channels () between them. Within each flow channel () is a foil () of corrugated material whose surfaces are coated with catalytic material apart from where they contact the sheets (). At each end of the reactor () are headers to supply gas mixtures to the flow channels (), the headers communicating with adjacent channels being separate. The reactor () enables different gas mixtures to be supplied to adjacent channels (), which may be at different pressures, and the corresponding chemical reactions are also different. Where one of the reactions is endothermic while the other reaction is exothermic, heat is transferred through the sheets () separating the adjacent channels (), from the exothermic reaction to the endothermic reaction. The reactor () may be used in a compact plant to perform steam/methane reforming, obtaining the necessary heat by catalytic methane combustion, and also for Fischer-Tropsch synthesis, so that the overall process involves conversion of methane to long-chain hydrocarbons.

Catalytic reactor

A catalyst support is made by coating a metal substrate with a solution containing a precursor for a ceramic and an amphiphilic compound, and treating the coating such that it forms a micelle structure. The coating is then treated to form a mesoporous ceramic coating on the metal substrate. The micelle structure acts as a template, so that the pores are of regular size. The active catalytic material can then be deposited in the pores. The metal substrate may for example be a corrugated foil, which can enable reaction heat to be dissipated from hot spots.

Methods of making and using a catalyst

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.
