Abstract

    

     

Features and Benefits

  • Novel and simplified process for producing commercially relevant for producing commercially relevant hydrocarbons from fatty acids.
  • Multifunctional catalyst promotes efficiency by enabling conversion of lipid biomass material in a single reactor.
  • Further conversion of reactants following decarboxylation offers a broad array of commercial products, e.g., renewable or "green" diesel, lubricants, petrochemical intermediates.

Technology

    

University of Louisville researchers have developed a novel process for converting fatty acids into branched, cyclic and aromatic hydrocarbons.  More specifically, the process has been shown to catalyze decarboxylation and further conversions of oleic acid to paraffins, branched and aromatic hydrocarbons.  The reactions are catalyzed by platinum supported on small pore zeolites and hydrotalcite.

During the process, an increase in reaction temperature yields increased decarboxylation and selectivity to heptadecane and dodecylbenzene among the products when using Pt-SAPO-34 as the catalyst.  Side products yielded by the process include branched isomers, paraffins, alkenes, and carboxylic acids such as nonanoic acid and decanoic.

The process provided by this invention enables a simplified and scalable method to produce a number of useful hydrocarbons for transportation fuel, lubricants and important intermediaries from an environmentally friendly, renewable resource.

     

Markets Addressed

    

Hydrocarbons are broadly used organic compounds that are commonly formulated as fuel for combustion, particularly in transportation fuel applications. Most hydrocarbons are obtained from processing and refining fossil fuels. The problem with fossil fuels as a sole or predominant source of hydrocarbons is that their supply is limited and unsustainable. Interest in the production of alternative fuel sources is on the rise globally due to a growing desire to steadily reduce CO2 emissions and dependency on nonrenewable fossil fuels.
