Abstract: A power system comprises an engine configured to combust an air/fuel mixture and produce a flow of exhaust gas; an exhaust passageway fluidly connected to the engine to receive the flow of exhaust gas; an exhaust gas recirculation loop fluidly connecting the exhaust passageway to a fuel intake for the engine; a first conversion zone containing a fuel reforming catalyst located within the exhaust gas recirculation loop; and a second conversion zone located within the exhaust gas recirculation loop separate from and downstream of the first conversion zone stream, the second conversion zone containing a fuel cracking catalyst.

Abstract: Zn-promoted and/or Ga-promoted cracking catalysts, such as cracking catalysts comprising an MSE framework zeolite or an MFI framework zeolite can provide unexpectedly superior conversion of branched paraffins when used as part of a catalyst during reforming of a hydrocarbon fuel stream. The conversion and reforming of the hydrocarbon fuel stream can occur, for example, in an internal combustion engine. The conversion and reforming can allow for formation of higher octane compounds from the branched paraffins.
