Abstract: Naphtha boiling range compositions are provided that can have improved combustion properties (relative to the research octane number of the composition) in spark ignition engines and/or compression ignition engines. The improved combustion properties can be achieved by controlling the total combined amounts of n-paraffins and isoparaffins that include a straight-chain propyl group (R1—CH2—CH2—CH2—R2). For such a straight-chain propyl group, R2 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin. R1 can correspond to a hydrogen atom, making the straight-chain propyl group a terminal n-propyl group; or R1 can correspond to any convenient CxHy group that can appear in a paraffin or isoparaffin.

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.
