    摘要： A method of producing from a kneaded mass pellets moulded to a uniform dimension, which comprises disposing a surface which travels while being maintained at a specified distance from an extrusion outlet of an extruder and substantially at right angles to the direction of extrusion, and extruding a kneaded mass from the extruder, causing the distal end of the rodlike mass being extruded from the extrusion outlet to contact said traveling surface, and breaking off said rodlike mass at the rim of the extrusion outlet by the motive force of the traveling surface.

    摘要： A method for the production of exhaust or waste gases purifying catalysts which comprises soaking a granular activated alumina in an aqueous solution containing trivalent chromium ions and hexavalent chromium ions in a chromic atomic ratio of 1:1 to 1:20 and having an adjusted pH of 0.5 to 4.5 as to deposit the chromium compounds onto the alumina support in an amount as chromium oxide of 5 to 30 percent by weight based on the weight of the catalyst, drying and calcining the so impregnated alumina support, treating the resulting supported composition with an aqueous solution of a compound of at least one metal selected from the group consisting of palladium and platinum as to deposit the metallic compound in an amount as the metal of 0.05 to 2 g/liter-catalyst on to the supported composition and, after drying, activating the so treated supported composition. The activation is performed either by calcining the composition at a temperature of 300* to 800*C in an oxidative atmosphere or by heating it at a temperature of 80* to 250*C in the presence of a vapourized organic reducing agent.
