Filed:

Jul 21, 2000

Appl. No.:

09/621596

Inventors:

Todd Howard Ballinger - Audubon PA
Paul Joseph Andersen - Plymouth Meeting PA

Assignee:

Johnson Matthey Public Limited Company - London

International Classification:

B01J 2906

US Classification:

502 66, 502 64, 502 65, 502 73, 502 74

Abstract:

An active metal, particularly cesium, impregnated hydrocarbon adsorbent, such as zeolite, comprises an improved hydrocarbon trap/oxidizing catalyst for use in effectively adsorbing hydrocarbons during automotive cold-start and subsequently desorbing, oxidizing and removing hydrocarbons during warmer operating conditions. The active metal modified hydrocarbon adsorbent may be combined in other forms of multi-layer automotive exhaust gas catalytic structures.

International Classification:

F01N 310

US Classification:

60299, 4232135, 4232391, 4232451, 423247, 502328, 502332, 502333, 502334, 502339

Abstract:

A platinum group metal three-way conversion catalyst composition containing a high temperature catalytic component and a low temperature catalytic component has each catalytic component present as separate distinct particles in the same washcoat layer. The catalyst composition is prepared from a washcoat slurry containing a high temperature catalyst support material, and a low temperature catalyst support material, each support material being of sufficiently large particle size so as to prevent each support material forming a solution or a sol with the liquid medium of the slurry. The platinum group metal or metals can be impregnated into each support material either after formation of the washcoat on a non-porous refractory, metallic or palletized substrate or before forming the washcoat slurry.

International Classification:

F01N 300

US Classification:

60285, 60274, 60284, 60289

Abstract:

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 550Â C. , preferably higher, in order to reduce sulphur poisoning of the catalyst and maintain the desired catalytic activity.

International Classification:

B01J 2300

US Classification:

502304, 502330

Abstract:

A process and composition for converting nitrogen oxides present in exhaust gases produced by an internal combustion engine utilize cobalt and at least one alkali metal or alkaline earth metal as a component of an adsorbent. The process involves contacting the exhaust gas with an adsorbent which adsorbs the nitrogen oxides in lean-burn conditions and recurrently reducing the oxygen concentration of the exhaust gas. During such periods of reduced oxygen concentration, the nitrogen oxides are then desorbed and reduced to nitrogen, thereby reducing the concentration of the nitrogen oxides in the exhaust gas. The composition of the adsorbent comprises an oxide support and at least two components loaded on the support and containing cobalt and at least one alkali metal or alkaline earth metal. The composition demonstrates improved activity at higher temperatures and improved thermal stability.

Abstract:

A system calculates the optimal allocation of two or more resources provided by a resource provider to a task within a computer system from a plurality of possible allocations. In doing so, the system calculates the total volume of an N-dimensional cube, where N is the number of resources provided by the resource provider, representing the respective amounts of resources available to be allocated. The system also calculates the average volume of the N-1 dimensional shapes forming the sides of the N-dimensional cube. The system then calculates, at least partly from the ratio of the total volume to the average volume, the balance resulting from the allocation of resources represented by the N-dimensional cube. The system then calculates the imbalance resulting from the allocation of resources at least partly from the balance and determines the smallest imbalance as the optimal allocation of resources.
