A method for production of an exhaust-gas routing device that has a housing, an elongated substrate, and a compensating element, includes the following steps. At least one parameter of the substrate and/or of the compensating element is determined A target parameter, which describes a variable linked to a target geometry of the housing, is determined based on the measured parameter of the substrate and/or of the compensating element. The substrate and the compensating element are arranged in the housing, and the housing is deformed with an overpressure factor which is determined on the basis of at least one previous deformation of a previously manufactured device. The housing is measured after the deformation, and the thus-established values are compared with the target parameter. An overpressure factor for the deformation of a subsequently manufactured device is adapted if a deviation from the target parameter is detected upon measuring which lies above a defined threshold value.

A bottom face processing method of a pillar-shaped honeycomb structure including steps of: preparing a pillar-shaped honeycomb structure including a plurality of first cells which extend in parallel with each other from a first bottom face to a second bottom face, and each of which is opened in the first bottom face and has a protruding plugged portion in the second bottom face, and a plurality of second cells each of which is adjacent to at least one of the first cells with a partition wall interposed therebetween, which extend in parallel with each other from the first bottom face to the second bottom face, and each of which has a protruding plugged portion in the first bottom face, and is opened in the second bottom face; and removing the protruding portion from the plugged portion of each of the first cells and the second cells of the pillar-shaped honeycomb structure.

Provided is a catalyst article for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The catalyst article has a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia.

A gaseous emissions treatment component is made by extruding a green ceramic mix through a die to form an extrusion having a honeycomb substrate with elongate cells extending its length and with the cells bounded by walls dividing adjacent cells from one another. Molten metal for use in induction heating of the component is placed in selected cells and is solidified by cooling.

The catalyst module is designed for use in an emission control system of a stationary incinerator. It comprises a stack frame, into which several mounting units are inserted strung together. The mounting units have a peripheral side wall as well as several partitions, which are entangled with one another and form a lattice with a plurality of mounting shafts, in which in each case one catalyst is inserted. The catalysts are pressed into position preferably with the interposition of an elastic fitting element.

A reactor cell for measuring gas and liquid permeation is disclosed. A hollow fiber is supported by and sealed into a first hole and a second hole of the reactor module. The first and second ends of the hollow fiber are sealed with a sealing solution. Methods for making and using the reactor cell are also disclosed. As made and used, the reactor cell further comprises a molecular sieving membrane that is uniform and free of defects grown on an inner bore surface of the hollow fiber.

In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises flowing insulation material from one end of the unit into selected ones of the elongate passages, the insulating material then being cured. The passages are selected so that the cured insulation material forms an internal thermal insulating barrier between a core zone of the unit and a radially outer zone of the unit. Passages in the inner and outer zones are free of insulation material and the honeycomb structure walls include walls crossing the insulating barrier.

A mounting assembly for mounting a diesel oxidation catalyst (DOC) system within a work vehicle may generally include a support bracket having a first side and a second side. The mounting assembly may also include a mount plate configured to be coupled to the first side of the bracket. The mount plate may include first and second plate walls and may define an elongated slot through the first plate wall. Additionally, the assembly may include a retention band configured to at least partially wrap around a housing of the DOC system between a first end configured to be coupled to the mount plate and a second end configured to be coupled to the second side of the support bracket. The mount plate may be configured to be moved laterally relative to the support bracket to allow the retention band to be tightened and loosened around the housing.
