A process for converting light paraffins and/or light hydrocarbons to a high octane gasoline composition is disclosed. The process involves: (1) oxidation of iso-paraffins to alkyl hydroperoxides and alcohol; (2) conversion of the alkyl hydroperoxides and alcohol to dialkyl peroxides; and (3) radical coupling of one or more iso-paraffins and/or iso-hydrocarbons using the dialkyl peroxides as radical initiators, thereby forming a gasoline composition comprising gasoline-range molecules including a C7 enriched gasoline composition having a road octane number (RON) greater than 100.

Production of high-value fuel mixtures from synthetic and biologically derived hydrocarbon molecules

This disclosure relates to compositions and methods of making an additized fuel composition comprising a base fuel composition and a randomly branched nitrate composition. The randomly branched nitrate composition includes a plurality of primary nitrate molecules, each molecule therein having an empirical chemical formula of CNO, wherein Cis a branched aliphatic moiety which may be the same or different for each molecule, n is an integer selected from the group consisting of 8, 9, 10, 11 and 12, at least one carbon atom in the branched aliphatic moiety being bound to three or more carbon atoms, a branching index ranging from 1.8 to 2.2, and greater than 80% of the branches in the aliphatic moiety being in other than the alpha position. The additized fuel composition may be diesel fuel composition or a gasoline fuel composition.
