  • Low emissions, high working capacity adsorbent and canister system
    Patent number: 11565239
    Abstract: The present description provides high working capacity adsorbents with low DBL bleed emission performance properties that allows the design of evaporative fuel emission control systems that are lower cost, simpler and more compact than those possible by prior art. Emission control canister systems comprising the adsorbent material demonstrate a relatively high gasoline working capacity, and low emissions.
    Type: Grant
    Filed: September 22, 2021
    Date of Patent: January 31, 2023
    Assignee: INGEVITY SOUTH CAROLINA, LLC
    Inventors: Laurence H. Hiltzik, James R. Miller, Roger S. Williams, Cameron I. Thomson, Michael G. Heim, Emma M. Card, Stephan Charles Cronin
