Abstract: A gaseous fuel engine system includes an exhaust controller coupled with a temperature sensor and a NOx sensor, and structured to actuate open an electrically actuated bypass valve to bypass an oxidation catalyst with exhaust, based on an exhaust temperature and an exhaust NOx amount to mitigate production of yellow smoke. Yellow smoke mitigation logic may run during startup and when the gaseous fuel engine is in a lower part of an engine load range. The yellow smoke mitigation logic can be selectively triggered in response to transient engine load increases when the gaseous fuel engine is operating in an upper part of an engine load range.

Abstract: A system and method for co-production of hydrogen and electrical power includes operating an engine having an electrical power generator connected thereto, and a hydrogen gas production plant, from a single source of gaseous fuel such that hydrogen extracted from a heated reformate provided by a partial oxidation catalyst is removed and collected for storage or sale while a tail gas is recirculated to an engine inlet to reduce NOx emissions during engine operation.

Abstract: An aftertreatment system is disclosed. The aftertreatment system can include a hydrolysis catalyst disposed within a first canister adjacent to a downstream end of the first canister and a nozzle positioned to inject reductant into the first canister upstream of the hydrolysis catalyst. A particulate collection device, which may be catalyzed to promote NOX reduction in the presence of the reductant, can be disposed within a second canister of the aftertreatment system adjacent to an upstream end thereof. An exhaust conduit can extend from the downstream end of the first canister to the upstream end of the second canister. An interior volume within the exhaust conduit can extend from an upstream end adjacent to and in fluid communication with the hydrolysis catalyst to a downstream end adjacent to and in fluid communication with the particulate collection device.

Abstract: A reactor assembly is provided. The reactor assembly includes a substrate and a first catalytic layer provided on the substrate. The first catalytic layer further includes a first temperature zone configured to operate at a first temperature. The first catalytic layer further includes a second temperature zone extending from the first temperature zone. The second temperature zone is configured to operate at a second temperature. The second temperature is lower than the first temperature. The reactor assembly also includes a diffusion barrier coating provided on the first catalytic layer. The diffusion barrier coating is configured to regulate a diffusion of gas phase oxygen therethrough for controlling the first temperature with respect to the second temperature.
