Systems for the catalytic activation and/or dehydrogenation of a paraffin feed stream that is enriched in C5 alkanes to produce olefins that are then hydrated in the presence of water to produce C5 alcohols. Optionally, paraffin isomers are separated and the n-paraffins isomerized prior to catalytic activation and/or dehydrogenation.

Systems for converting light paraffins to alcohols

Systems operable to produce liquid transportation fuels by converting a hydrocarbon feed stream comprising both isopentane and n-pentane. The system comprises a first separator operable to separate a hydrocarbon feed stream into a first fraction that predominantly comprises isopentane and a second fraction that predominantly comprises n-pentane and some C6 paraffins. An isomerization reactor isomerizes the second fraction to convert at least a portion of the n-pentane to isopentane. The resulting isomerization effluent is combined with the hydrocarbon feed stream, allowing the isopentane produced in the isomerization reactor to be separated into the first fraction in the first separator. An activation reactor catalytically activates the first fraction to produce an activation effluent comprising olefins and aromatics. Certain embodiments additionally comprise either an oligomerization reactor or and alkylation reactor operable to further upgrade the activation effluent, thereby enhancing yields.

Systems for isomerization and catalytic activation of pentane-enriched hydrocarbon mixtures

The present disclosure relates to processes that catalytically convert a hydrocarbon feed stream predominantly comprising both isopentane and n-pentane to yield upgraded hydrocarbon products that are suitable for use either as a blend component of liquid transportation fuels or as an intermediate in the production of other value-added chemicals. The hydrocarbon feed stream is isomerized in a first reaction zone to convert at least a portion of the n-pentane to isopentane, followed by catalytic-activation of the isomerization effluent in a second reaction zone with an activation catalyst to produce an activation effluent. The process increases the conversion of the hydrocarbon feed stream to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. Certain embodiments provide for further upgrading of at least a portion of the activation effluent by either oligomerization or alkylation.

Isomerization, catalytic activation and oligomerization of pentane-enriched hydrocarbon mixtures

The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. Certain embodiments additionally comprise mixing at least a portion of the two effluents and contacting with an alkylation catalyst to provide enhanced yields of mono-alkylated aromatics that are suitable for use as a blend component of liquid transportation fuels or other value-added chemical products.
