  • Simultaneous reaction and separation of chemicals
    Patent number: 11814285
    Abstract: The reaction rate of hydrocarbon pyrolysis can be increased to produce solid carbon and hydrogen by the use of molten materials which have catalytic functionality to increase the rate of reaction and physical properties that facilitate the formation and contamination-free separation of the solid carbon. Processes, materials, reactor configurations, and conditions are disclosed whereby methane and other hydrocarbons can be decomposed at high reaction rates into hydrogen gas and carbon products without any carbon oxides in a single reaction step. The process also makes use of specific properties of selected materials with unique solubilities and/or wettability of products into (and/or by) the molten phase to facilitate generation of purified products and increased conversion in more general reactions.
    Type: Grant
    Filed: November 16, 2018
    Date of Patent: November 14, 2023
    Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
    Inventors: Eric W. McFarland, Ches Upham, Jiren Zeng, Clarke Palmer, Shizhao Su, Davide Mannini, Dohyung Kang, Nazanin Rahimi, Horia Metiu, Michael Gordon
