Project TitleCatalytic Isomerization of Linear Olefinic Hydrocarbons (11060)
Track Code11060
Short Description



Features and Benefits

  • Allows for conversion of linear olefinic hydrocarbons containing four or more carbon atoms into branched analogs useful as fuels, lubricants and other products
  • Improves the feasibility of more widespread adoption and use of hydrocarbons derived from renewable sources


*This technology is available for licensing, further development, or industrial partnering




University of Louisville researchers have developed a novel and industrially applicable catalytic process for the isomerization of linear olefinic hydrocarbons to branched olefinic hydrocarbons. The isomerization reaction occurs over gallium-niobium oxide catalysts, and comprises the steps of contacting linear olefinic hydrocarbon reactants with the catalyst and isolating the branched olefinic hydrocarbon products.


Markets Addressed


Branched hydrocarbons are preferred constituents of many fuels, lubricants and other products. They are preferred constituents of gasoline, diesel, kerosene, jet fuels. They have high octane numbers and energy densities and low freezing points. Conventionally, such fuels and petrochemicals are obtained from crude petroleum oil by distillation and further refining. Due to the dwindling supply of petroleum and the adverse environmental impact of carbonaceous fossil fuels due to CO2 emissions, attempts are being made worldwide to produce hydrocarbon products from alternate, renewable sources of biological origin. Long chain hydrocarbons with 10 to 20 carbon atoms can be obtained from biological lipid raw material, such as triglycerides, fatty acids and fatty acid alkyl esters by deoxygenation and decarboxylation. Deoxygenation of fatty acids, fatty acid esters and triglycerides, however, yields only the normal, straight linear chain hydrocarbons. To be useful as fuels, such as gasoline, kerosene or jet fuel, it is desirable to convert these linear hydrocarbons to their branched analogs. This technology addresses the need for an industrially applicable process for the manufacture of branched chain hydrocarbons from linear paraffinic hydrocarbons.


Technology Status
