Matthew J. Wulfers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240034949
    Abstract: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that predominantly comprises isobutane. The feed stream is catalytically-activated in two separate reaction zones arranged in series in a manner that minimizes the production of C1-C3 light paraffins and is tolerant to the presence of typical catalyst poisons. The first reaction zone is selective for conversion of the feed stream to predominantly olefins and some aromatics. The second reaction zone is maintained at a lower temperature and a higher pressure and is selective for converting olefins to monocyclic aromatics which facilitates further feed stream olefination. Certain embodiments contact the activation effluent with an alkylation catalyst to provide enhanced yields of upgraded hydrocarbon products that meet specifications for a transportation fuel blend component.

  • Patent number: 11845719
    Abstract: 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.

  • Patent number: 10988696
    Abstract: 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.
