Abstract: A support structure (53) for securing a catalyst structure (52) comprising a multiplicity of longitudinally disposed channels for passage of a flowing gas mixture within a reactor, said support structure being comprised of a monolithic open celled or honeycomb-like structure formed by thin strips or ribs of high temperature resistant metal or ceramic which abuts against one end of the catalyst structure, and extends in a direction perpendicular to the longitudinal axis of the catalyst structure to essentially cover an end face (at either the inlet end or outlet end or both) of the catalyst structure with the support structure being secured (54) on its periphery to the reactor wall. The strips or ribs making up the support structure are bounded together to form a unitary structure having cellular openings at least as large as the catalyst structure channel openings. The cellular openings in the support structure are also positioned to be in fluid communication with the channels of the catalyst structure thus affording essentially unaltered gas flow (50) from the catalyst structure through the support structure.

Abstract: A method for reducing the amount of carbon monoxide produced in the combination of carbonaceous fuels. The fuel (1) is coated on at least a portion of its exterior surface with a microporous layer of solid particulate matter (9) which is non-combustible at temperatures in which the carbonaceous fuel combusts. This invention is particularly applicable in the reduction of carbon monoxide in the burning of carbonaceous fuel elements found in currently available 'smokeless' cigarettes.

Abstract: Cette invention concerne un procédé de combustion ayant une série d'étages dans lesquels un mélange (16, 18) contenant du gaz oxygène et un carburant brûle par étapes en utilisant une série de catalyseurs spécifiques et des structures catalytiques (figure 2) et, éventuellement, une zone de combustion homogène finale pour produire un gaz brûlé à une température sélectionnée de préférence entre 1050 °C et 1700 °C. En fonction de la pression de fonctionnement, il peut exister deux ou trois étages catalytiques (étages 1, 2 et 3). Le choix des catalyseurs et l'utilisation des structures spécifiques, y compris celles utilisant un échange de chaleur intégral (44), ont pour résultat un catalyseur et son support qui sont stables en raison de leur température relativement faible, ne se détériorent pas, et le gaz de combustion produit est à une température appropriée pour être utilisé dans une turbine à gaz, un four, une chaudière ou autres, mais possède une teneur NOx faible. Ni du carburant ni de l'air est ajouté au processus de combustion, sauf dans l'étage initial.

Abstract: Procédé de réduction de la quantité de monoxyde de carbone produit dans la combinaison de combustibles carbonés. On enduit le combustible (1), sur au moins une partie de sa surface extérieure, d'une couche microporeuse de matière particulaire solide (9) non combustible aux températures auxquelles le combustible carboné brûle. L'invention s'applique notamment à la réduction de monoxyde de carbone dans la combustion d'éléments de combustible carboné rencontrés dans les cigarettes "sans fumée" couramment disponibles.
