Filed:

Aug 1, 2008

Appl. No.:

12/184274

Inventors:

Ke Liu - Rancho Santa Margarita CA, US
Gregg Anthony Deluga - Playa del Rey CA, US
Dan Hancu - Clifton Park NY, US
Daniel George Norton - Niskayuna NY, US
Frederic Vitse - Knoxville TN, US
Benjamin Hale Winkler - Albany NY, US

Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY

International Classification:

F01N 3/20

US Classification:

60286, 60301

Abstract:

A system includes an exhaust conduit configured to conduct a stream of exhaust gas, wherein the exhaust conduit comprises a selective catalytic reduction catalyst reactor comprising a first catalyst composition; an fuel source configured to introduce a fuel into the exhaust gas stream within the exhaust conduit upstream of the selective catalytic reduction catalyst reactor; a catalytic partial oxidation reformer in fluid communication with the exhaust gas stream and upstream from the selective catalytic reduction catalyst reactor, wherein the catalytic partial oxidation reformer can introduce a hydrogen-rich syngas co-reductant into the exhaust gas stream, when a temperature of the exhaust fluid is less than a determined threshold temperature.

Abstract:

A reductant producing apparatus and method is provided, the apparatus includes a catalyst attached to an encasement. The encasement has a first and second intake formed therein that are fluidly coupled to the catalyst. The first intake configured to allow entry of a hydrocarbon fuel into the encasement. The second intake is configured to allow entry of oxygen into the encasement. The catalyst is configured to catalyze an autothermal reaction to convert a mixture into a plurality of reductants comprising a plurality of hydrocarbons having a hydrocarbon chain length that is less than a hydrocarbon chain length of hydrocarbons in the hydrocarbon fuel. The mixture comprises the hydrocarbon fuel and the oxygen, and the mixture has a carbon-to-oxygen ratio that is greater than a one-to-one ratio.

International Classification:

F01N 3/10

US Classification:

60295, 60299

Abstract:

A system comprising a fuel converter comprising a catalyst composition capable of converting a fuel into a selected one or both of a syngas reductant and a short chain hydrocarbon reductant, wherein the catalyst composition comprises: cracking sites that perform a cracking function when a temperature of an exhaust fluid is greater than a predetermined threshold temperature, wherein the cracking function converts long chain hydrocarbon molecules to short chain hydrocarbon molecules; and partial oxidation sites that perform a catalytic partial oxidation function when the temperature of the exhaust fluid is less than the predetermined threshold temperature, wherein the catalytic partial oxidation function oxidizes the fuel to produce the syngas reductant; and a selective catalytic reduction catalyst reactor in fluid communication with the fuel converter and the exhaust fluid.
