    摘要: A catalytic converter for treating pollutants contained in exhaust gas from an internal combustion engine, includes a chamber having an inlet disposed at a first end of the chamber for introduction of the exhaust gas and an outlet disposed at a second end of the chamber opposite the first end for discharge of the exhaust gas from the chamber after treatment; a front plate provided at the inlet of the chamber and having defined therein a plurality of openings; first, inner, and second, outer, fixed cones positioned within the chamber, disposed in a spaced apart and parallel relationship to one another, and having a plurality of spaced apart holes defined therein, wherein the plurality of holes defined in the first fixed cone are disposed in a staggered relationship to the plurality of holes of the second fixed cone, and wherein the first fixed cone defines with the front plate a first zone within the chamber; a catalyst bed which is disposed in the space defined between the first and second fixed cones, through which the exhaust gas entering the chamber through the inlet flows radially there through, and which contains catalyst in use; a diffuser section provided in the second end of the chamber, through which the outlet is provided, and within which is defined a second zone; a conical member extending from the first fixed cone into the diffuser section for providing a reduced jet effect of the exhaust gas entering the chamber; and a feeding zone for the catalyst defined by closure of a wall surface of the first and second fixed cones adjacent to the inlet.

    摘要: A process for the preparation of CNSL phenoxy carboxylic acid derivatives for use as an additive in a lubricant composition so as to impart improved rust inhibiting properties, including the steps of (a) partially hydrogenating distilled technical cashew nut shell liquid with palladium or nickel or platinum catalyst; to hydrogenate the olefinic chain; (b) reacting cashew nut shell liquid or partially hydrogenated technical cashew nut shell liquid with halogeno carboxylic acid derivatives to obtain unpolymerized cashew nut shell liquid phenoxy carboxylic acid derivatives, the reaction being carried out at a temperature ranging from 20 to 140° C. A lubricant containing a major proportion of a material selected from the group consisting of an oil of lubricating viscosity and a grease; and remainder an additive including CNSL phenoxy carboxylic acid derivative prepared by the foregoing process.
