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.,

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 application relates to processes and systems that use a furfural compound for producing five-membered carbocyclic rings that are unsaturated, such as cyclopentene and cyclopentadiene. Examples methods for conversion of furfural compounds may include converting a furfural compound to at least a five-membered, saturated carbocyclic ring, and converting the five-membered, saturated carbocyclic ring in a presence of a catalyst to at least a five-membered, unsaturated carbocyclic ring.

Abstract: Processes and systems for producing olefin epoxides with three or more carbon atoms by oxidation of the corresponding branched hydrocarbons using oxygen are disclosed. An example process for producing olefin epoxides may include oxidizing a branched alkane to produce at least an organic hydroperoxide. The example process may further include epoxidizing a branched alkene by a catalytic reaction with least a portion of the organic hydroperoxide to produce at least an olefin epoxide and an alcohol. The example process may further include converting at least a portion of the alcohol to either additional branched alkane and/or additional branched alkene.

Abstract: The present disclosure generally relates to a process for converting a hydrocarbon feed including introducing a hydrocarbon feed comprising a C1+ alkane to a catalyst composition in a reactor, the catalyst composition comprising a Group 6-Group 15 metal supported on a support; and irradiating the hydrocarbon feed and the catalyst composition with electromagnetic energy in the reactor at reactor conditions to produce a product comprising a C2+ alkane, wherein the C2+ alkane of the product is heavier than the C1+ alkane in the hydrocarbon feed.
