摘要： This invention relates to an electrically-heated catalyst (EHC) and a start-up method of a gas turbine engine for combusting a hydrocarbonaceous fuel/oxygen-containing gas mixture using this electrically-heated catalyst. The catalytic structure is electrically heated to a predetermined temperature prior to start up of the turbine so as to reduce emissions during the start-up of the system. The EHC unit is a stacked or spirally wound layering of flat and corrugated thin metal foils which forms a plurality of axially-extending, longitudinal channels. The channels are preferably coated on one surface with a catalytic material, leaving the other surface free from the reaction to act as a heat sink, making the design an IHE (integral heat exchange) catalytic unit. The preferred embodiment of the EHC has electrodes outside of the fuel/oxygen-containing mixture stream, and uses electrical power having a predetermined voltage in the range of 100 to 200 volts to heat the unit. A method for using the EHC in the start-up of a gas turbine is also disclosed wherein an electrical power is applied to heat the EHC a predetermined temperature prior to the fuel/oxygen-containing mixture being introduced and may be left on for a certain period of time after the introduction of the fuel/oxygen-containing mixture. The EHC may be maintained at the desired predetermined temperature by modulating the applied voltage. The electrical power is terminated when any one of several conditions are met including when the heat of the catalytic reaction is sufficient to maintain the catalyst at its steady-state condition or when a certain period of time has elapsed.

摘要： This invention is an improved catalyst structure and its use in highly exothermic processes like catalytic combustion. This improved catalyst structure employs integral heat exchange in an array of longitudinally disposed adjacent reaction passage-ways or channels, which are either catalyst-coated or catalyst-free, wherein the configuration of the catalyst-coated channels differs from the non-catalyst channels such that, when applied in exothermic reaction processes, such as catalytic combustion, the desired reaction is promoted in the catalytic channels and substantially limited in the non-catalyst channels. The invention further comprises an improved reaction system and process for combustion of a fuel wherein catalytic combustion using a catalyst structure employing integral heat exchange, preferably the improved structures of the invention, affords a partially-combusted, gaseous product which is passed to a homogeneous combustion zone where complete combustion is promoted by means of a flameholder.

摘要： A matrix for a catalytic reactor used for exhaust gas purification in internal combustion engines includes corrugated strips of sheet steel that are coatable with catalyst material. The sheets are folded to produce several layers in a tubular housing which is traversed by a flow of exhaust gases. The individual layers are part of a continuous length or strip of sheet steel which is folded in a meandering or serpentine fashion. A zigzag folding pattern is especially preferred. This arrangement simplifies manufacturing and results in improved radial equalization of exhaust gases. Uniformity of flow profile is improved by cutouts provided in the matrix material.

摘要： A honeycomb body is formed of alternating layers that are smooth and partially structured. The layers form cavities that allow a fluid to flow in an axial flow direction. The structured layers have structural extremities in contact with smooth neighboring layers and inverted sections in the vicinity of their structural extremities. The sections protrude into the cavities and have a form approximately inverse of the structural extremities in a cross-section through the honeycomb body that runs perpendicularly to the flow direction in such a way that breaks are formed in the structural extremities. Counter-structures are configured in the vicinity of the inverted sections and/or structural extremities in the smooth layers. The structures engage with the structural extremities and/or inverted section. In the honeycomb body, relative displacements of the two layers in the flow direction are prevented by the co-operation of the inverted sections and the counter-structures.

摘要： A honeycomb body that is formed of alternating layers that are substantially smooth and layers that are at least partially structured, in particular a catalytic converter support and/or filter, preferably for the exhaust gas system of a motor vehicle. The layers form cavities that allow a fluid to flow in an axial flow direction. The structured layers have structural extremities in contact with smooth neighboring layers and inverted sections in the vicinity of their structural extremities. The sections protrude into the cavities and have a form approximately inverse of the structural extremities in a cross-section through the honeycomb body that runs perpendicularly to the flow direction in such a way that breaks are formed in the structural extremities in the vicinity of the inverted sections. Counter-structures are configured in the vicinity of the inverted sections and/or structural extremities in the essentially smooth layers. The structures engage with the structural extremities and/or inverted sections, in particular in a positive fit. In the inventive honeycomb body, relative displacements of the two layers in the flow direction are prevented by the co-operation of the inverted sections and the counter-structures that are allocated to the latter, by the engagement of the counter-structure with the inverted section. This also prevents the telescoping of honeycomb bodies.
