Abstract: An example method includes determining that a selective catalytic reduction (SCR) component having a zeolite-based catalyst is contaminated with platinum (Pt). The method further includes elevating the temperature of the SCR component to at least 600° C. in response to the determining the catalytic component is contaminated with Pt, and maintaining the elevated temperature of the catalytic component for a predetermined time period thereby restoring reduction activity of the catalyst.

Abstract: A technique is described including receiving a hydrocarbon stream, and heating the hydrocarbon stream with an exhaust steam from an internal combustion engine. This technique may include reacting the hydrocarbon stream catalytically to produce hydrogen and a modified hydrocarbon stream having a lower saturation state than the hydrocarbon stream, recovering energy from the hydrogen stream, and/or providing the modified hydrocarbon stream to a fuel supply for the internal combustion engine.
