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: An integrated process for converting low-value paraffinic materials to high octane gasoline and high-cetane diesel light is disclosed. The process involves: (1) oxidation of an iso-paraffin to alkyl hydroperoxide and alcohol; (2) converting the alkyl hydroperoxide and alcohol to dialkyl peroxide; (3) converting low-octane, paraffinic gasoline molecules using the dialkyl peroxides as radical initiators, thereby forming high-cetane diesel, while the dialkyl peroxide is converted to an alcohol; (4) converting the alcohol to an olefin; and (5) alkylating the olefin with iso-butane to form high-octane alkylate. The net reaction is thus conversion of iso-paraffin to high-octane gasoline alkylate, and conversion of low-octane paraffinic gasoline to high-cetane diesel.
