摘要： A catalyst system includes a three-way catalyst (TWC) mounted underfloor and an engine management system programmed to initiate an enrichment of the exhaust gases exiting the engine with at least one of CO and hydrocarbons and to add secondary air to the exhaust gases in the exhaust passage upstream of the TWC. This periodic enrichment and addition of secondary air causes catalytic oxidation of the at least one of CO and hydrocarbons over the TWC thereby raising the underfloor TWC temperature to at least 550° C., preferably higher, in order to reduce sulphur poisoning of the catalyst and maintain the desired catalytic activity.

摘要： A method of using a catalyst comprises exposing a catalyst to at least one reactant in a chemical process. The catalyst comprises copper and a small pore molecular sieve having a maximum ring size of eight tetrahedral atoms. The chemical process undergoes at least one period of exposure to a reducing atmosphere. The catalyst has an initial activity and the catalyst has a final activity after the at least one period of exposure to the reducing atmosphere. The final activity is within 30% of the initial activity at a temperature between 200 and 500° C.

摘要： An oxidation catalyst comprises an extruded solid body comprising: 10-95% by weight of at least one binder/matrix component; 5-90% by weight of a zeolitic molecular sieve, a non-zeolitic molecular sieve or a mixture of any two or more thereof; and 0-80% by weight optionally stabilized ceria, which catalyst comprising at least one precious metal and optionally at least one non-precious metal, wherein: (i) a majority of the at least one precious metal is located at a surface of the extruded solid body; (ii) the at least one precious metal is carried in one or more coating layer(s) on a surface; (iii) at least one metal is present throughout the extruded solid body and in a higher concentration at a surface; (iv) at least one metal is present throughout the extruded solid body and in a coating layer(s) on a surface; or (v) a combination of (ii) and (iii).
