摘要： A catalyst for exhaust gas purification is capable of purifying the hydrocarbons, nitrogen oxides and carbon monoxide present in the exhaust gas discharged from an internal combustion engine. The catalyst has a monolithic carrier and a catalyst layer containing Pd, Ba and a heat-resistant inorganic oxide, formed on the carrier. The amount of Pd supported on monolithic carrier is 100-300 g per ft3 of monolithic carrier (3.53×10−3 to 1.06×10−2 g per cc of monolithic carrier), the amount of Ba supported on monolithic carrier is 0.010-0.060 g per cc of monolithic carrier in terms of BaO, and the weight ratio of Pd and Ba as expressed as BaO is 1:2 to 1:10. This catalyst for exhaust gas purification is superior particularly in hydrocarbon purification for a low-temperature fuel-rich exhaust gas (such as exhaust gas emitted during cold start) of automobile.

摘要： An extruding die for forming finned ceramic honeycomb structures includes extruding forming grooves for extruding a ceramic material therethrough and a plurality of material supply apertures for supplying the ceramic material into the extruding die. The extruding forming grooves open at a front surface of the extruding die and intersect with each other in the form of a mesh corresponding to a sectional configuration of a ceramic honeycomb structure. The material supply apertures open at a rear surface of the extruding die and communicate with the extruding forming grooves at intersecting zones thereof. The extruding die comprises fin forming grooves branched from the extruding forming grooves for forming fins, and the material supply apertures communicate with at least parts of the fin forming grooves. In extruding a ceramic material with this extruding die to form a ceramic honeycomb structure, it is easily formed uniform in density in its entirety including fins, thereby completely preventing the fins from falling off during extruding and preventing cracks from occurring in drying or firing.
