  • Patent number: 10240099
    Abstract: Processes for the production of transportation fuel from a renewable feedstock. A catalyst is used which is more selective to hydrodeoxygenate the fatty acid side chains compared to decarboxylation and decarbonylation reactions. A gaseous mixture of carbon monoxide and hydrogen can be supplied to the conversion zone. Water may also be introduced into the conversion zone to increase the amount of hydrogen.
    Type: Grant
    Filed: September 12, 2017
    Date of Patent: March 26, 2019
    Assignee: UOP LLC
    Inventors: Krishna Mani, Kanchan Dutta, Avnish Kumar, Anjan Ray
  • Patent number: 9982198
    Abstract: Processes for pyrolyzing biomass. A catalyst is used to both pyrolyze and deoxygenate the biomass within the pyrolysis zone. A source of carbon monoxide is also passed to the pyrolysis reactor. The source of carbon monoxide may comprise a stream of gas that includes carbon monoxide, or a material capable of generating or being converted in carbon monoxide within the pyrolysis zone. The carbon monoxide may be used as a reactant for a water gas shift reaction or as a reducing agent to remove oxygen from oxygenated hydrocarbons. The catalyst preferably comprises iron (III) oxide.

  • Patent number: 9914883
    Abstract: Processes for the production of transportation fuel from a renewable feedstock. A gaseous mixture of carbon monoxide and hydrogen is used to deoxygenate and hydrogenate the glycerides to produce long chain hydrocarbons. The hydrocarbons may be isomerized to improve cold flow properties to provide a diesel fuel. Prior to isomerization, the long chain hydrocarbons can be separated or the separation can be after isomerization. Recycle gas streams from the isomerization and the deoxygenation and hydrogenation reactions may be used to supply at least a portion of the gaseous mixture of carbon monoxide and hydrogen. Synthesis gas may also be used to supply at least a portion of the gaseous mixture of carbon monoxide and hydrogen.

  • Publication number: 20170037322
    Abstract: Processes for the production of transportation fuel from a renewable feedstock. A gaseous mixture of carbon monoxide and hydrogen is used to deoxygenate and hydrogenate the glycerides to produce long chain hydrocarbons. Water is also introduced into the reaction zone to increase the amount of hydrogen and to increase the utilization of carbon monoxide within the reaction zone. Synthesis gas may also be used to supply at least a portion of the gaseous mixture of carbon monoxide and hydrogen. The amount of hydrogen equivalents in the reaction zone is at least 100% of a stoichiometric hydrogen demand within the reaction zone.
