Jiawen REN 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).

  • Patent number: 10730751
    Abstract: A system and process for producing carbon nano-materials is disclosed. A carbonate material such as Li2CO3 is heated via a furnace to transform into molten carbonate. CO2 is bubbled into the molten carbonate. The molten carbonate is subjected to electrolysis by passing current from an anode to a cathode. A transition metal nucleation agent is added to result in nucleation sites that grow carbon nano-materials at the cathode. This process separates oxygen at the anode and carbon nano-materials at the cathode. The characteristics of the carbon nano-material may be controlled by varying current density, feed gas, transition metal composition, temperature, viscosity and electrolyte composition.
    Type: Grant

  • Publication number: 20160168473
    Abstract: Methods and systems for producing one or more alkanes from biomass by hydrodeoxygenation are disclosed. Biomass may be converted to one or more alkanes by heating the biomass with a catalyst mixture that includes a noble metal and at least one of a transition metal and derivative thereof. The catalyst mixture may further include a solid acid. Heating may be performed at a single temperature and pressure.
