Publication number: 20240075452Abstract: Processes are described for removal of CO2 from a CO2-containing gas comprising water vapor, including: (a) contacting the CO2-containing gas comprising water vapor with an alkali metal carbonate adsorbent under conditions causing (i) the water vapor in the CO2-containing gas comprising water vapor to react with the alkali metal carbonate to form a corresponding alkali metal carbonate hydrate, and (ii) the corresponding alkali metal carbonate hydrate to react with CO2 in the CO2-containing gas comprising water vapor to form a corresponding alkali metal sesquicarbonate; and (b) reacting the alkali metal sesquicarbonate under conditions effective to recover CO2 and to regenerate alkali metal carbonate hydrate adsorbent therefrom. Systems for carrying out such process are also described, which are applicable to direct air capture (DAC) of CO2, as well as to treatment of CO2-containing flue gases from power plants and other oxidation and combustion sources.Type: ApplicationFiled: October 25, 2023Publication date: March 7, 2024Inventors: Tyson Lee LANIGAN-ATKINS, Jian Ping SHEN, Raghubir Prasad GUPTA, Cory Elliott SANDERSON

Patent number: 11491457Abstract: Zinc oxide-based sorbents, and processes for preparing and using them are provided, wherein the sorbents are preferably used to remove one or more reduced sulfur species from gas streams. The sorbents contain an active zinc component, optionally in combination with one or more promoter components and/or one or more substantially inert components. The active zinc component is a two-phase material, consisting essentially of a zinc oxide (ZnO) phase and a zinc aluminate (ZnAl2O4) phase. Each of the two phases is characterized by a relatively small crystallite size of typically less than about 50 nm (500 Angstroms). Preferably the sorbents are prepared by using an alkali metal base to convert a precursor mixture, containing a precipitated zinc oxide precursor and a precipitated aluminum oxide precursor, to the two-phase, active zinc oxide containing component, with the resulting sorbent having a sodium level within a desired range.Type: GrantFiled: August 1, 2018Date of Patent: November 8, 2022Assignee: Research Triangle InstituteInventors: Jian-Ping Shen, Jason S. Norman, Brian S. Turk, Raghubir Gupta

Publication number: 20220219992Abstract: A chromium-free catalyst for use in a fluidized bed reactor is described. The catalyst comprises 45-70 wt % Fe2O3, 5-15 wt % CuO, 20-35 wt % Al2O3, 10-20 wt % ZnO, and 1-15 wt % K2CO3. The catalyst has a Davison Index (DI %) of less than or equal to 15. A method for converting carbon monoxide (CO) into carbon-dioxide (CO2) using the catalyst is described. The method includes introducing H2O and CO into a fluidized bed reactor having an operating temperature between about 375° C. and about 450° C. and comprising the chromium free catalyst. The CO conversion is at least 60%.Type: ApplicationFiled: April 22, 2020Publication date: July 14, 2022Inventors: Jian-Ping SHEN, Brian TURK, Pradeepkumar SHARMA, David DENTON
