Catalytic activation and alkylation of isopentane-enriched mixtures
ActiveUS10815438B2Increase productionReduce productionHydrocarbon by dehydrogenationCatalytic crackingAlkanePtru catalyst
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.
