Hwiyoon Noh 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).

  • Hydrocarbon adsorption and desorption complex comprising zeolite with controlled cation ratio and preparation method therefor
    Patent number: 11666886
    Abstract: Disclosed are a hydrocarbon adsorption and desorption complex showing hydrocarbon adsorption and oxidation performance by controlling the cation ratio in zeolite, and a preparation method therefor. The hydrocarbon adsorption and desorption complex controls a cation ratio to exhibit the excellent hydrocarbon adsorption ability and oxidation performance even at a temperature lower than the catalyst activation temperature, and increases hydrothermal stability of the hydrocarbon adsorption and desorption complex through hydrothermal treatment to exhibit the excellent hydrocarbon adsorption and desorption performance even in a situation where water is present at a high temperature.
    Type: Grant
    Filed: November 23, 2021
    Date of Patent: June 6, 2023
    Assignee: Korea University Research and Business Foundation
    Inventors: Jungkyu Choi, Kwan-Young Lee, Jinseong Kim, Eunhee Jang, Hwiyoon Noh
  • Hydrocarbon adsorbent
    Patent number: 11666887
    Abstract: A hydrocarbon adsorbent includes a core-shell particle including a core and a shell surrounding the core, wherein the core includes ion-exchanged zeolite that is ion-exchanged with a metal other than silicon (Si) and aluminum (Al) and the shell includes a mesoporous metal oxide.

  • Catalyst for Adsorbing Hydrocarbon and Hydrocarbon Trap Comprising the Same
    Publication number: 20220152600
    Abstract: A catalyst for adsorbing hydrocarbon includes a first catalyst configured to adsorb short-chain hydrocarbons and including zeolites having a pore size of about 0.30 nm to about 0.44 nm and a second catalyst configured to adsorb a long-chain hydrocarbon and including zeolites ion-exchanged with a transition metal. The catalyst can be coated on a substrate of a hydrocarbon trap.
