    Abstract: A catalyst carrier is a piece carrier, and a plurality of waveform groove sections is formed on the piece carrier. In the piece carrier, the groove sections includes a plurality of upward grooves and a plurality of downward grooves. The upward grooves and downward grooves are arranged alternatively with a part of an opening of each upward groove being overlapped with a part of an opening of a respective downward grooves, so as to form a plurality of outward flowing channels and a plurality of inward flowing channels which are communicated with outer environment. Catalyst is coated upon the surfaces of the upward grooves and downward grooves. Thereby, the total area for coating catalyst is increased and the air is turbulent as flowing through the piece carrier.

    Abstract: A pliable refractory metal carrier (46) may have coated thereon an anchor layer (47) to improve adherence to the carrier (46) of a catalytic coating (48). The conformable catalyst member (26, 82, 82null, 126, 226, 326) may be bent to conform to a curved or bent exhaust pipe (20, 220, 320) within which it is mounted. The pliable metal carrier may be in the form of a tube such as carrier (46) having perforations (54) formed therein, or it may be a metal strip (76) which is folded into accordion pleats (80) and has perforations (78) formed therein. The perforations (54, 78) serve to permit the passage of exhaust gas therethrough. A series of interior closures (58) and annular baffles (60) may be provided to import a serpentine flow path to gases flowed through an exhaust pipe (22) containing a conformable catalyst member (226) therein. A mounting member (68) may be supplied to fasten one end of the conformable catalyst member (226) to the discharge end of an exhaust pipe (220).

    Abstract: An exhaust gas purifying catalyst capable of exerting excellent NO. purifying capability even at high exhaust gas temperatures, exceeding 500null C., is provided. The catalyst is an absorption reduction-type NOx, purifying catalyst comprising an NOx absorbent obtained by loading at least one alkali metal or alkaline earth metal on a crystalline ZrO2 composite oxide having added thereto at least one trivalent rare earth metal or divalent alkaline earth metal. Preferably, aluminum is further supported on the ZrO2 composite oxide. The NOx absorbent is considered to have an NOx absorption mechanism that an electron released from the alkali metal or the like enters into an oxygen vacancy part of the crystalline ZrO2 and this oxygen vacancy part functions as a strong base site for donating an electron to an electrophilic component such as NOx.

    Abstract: A honeycomb body made from a ceramic material with improved radial pressure resistance that is of cylindrical shape and features a first and a second end face and a cylindrical shell and that is traversed from one end face to the other by axially parallel channels formed by channel walls and distributed across the cross section of the honeycomb body in a regular grid pattern, in which design an outer marginal zone of the honeycomb body, the thickness of which amounts to several channel diameters, encloses a central area. The increase in radial pressure resistance of the honeycomb body is achieved by reinforcing the ceramic material of the cylindrical shell and of the channel walls in the outer marginal zone of the honeycomb body by depositing on or in it one or several inorganic substances for the purpose of increasing its mechanical stability.
