Abstract: 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.

Abstract: The present disclosure provides processes to convert paraffins to corresponding olefins and or heavier hydrocarbons. In at least one embodiment, a process includes introducing, at a temperature of from about 50° C. to about 500° C., a hydrocarbon feed comprising paraffins to a first metal oxide comprising one or more group 1 to group 17 metal and one or more oxygen. The process includes obtaining a product mixture comprising one or more C3-C50 cyclic olefins, one or more C2-C50 acyclic olefins, one or more C5-C200 hydrocarbons, such as one or more C5-C100 hydrocarbons, or a mixture thereof. In at least one embodiment, the product mixture is substantially free of H2 (e.g.,
