Title: Sequential Oxygen Reduction and Adsorption for Carbon Dioxide Purification for Flue Gas Applications

Abstract

Sequestration or utilization of carbon dioxide (CO ₂ ) produced from fossil fuels depends on the ability to transform flue gas into purified streams. Recent developments in oxy‐combustion have improved the efficiency of energy generation and carbon capture (>90% CO ₂ ). The subsequent removal of oxygen (O ₂ ) from this flue gas is critical, but such a process is energy intensive, technologically challenging, and unsolved. Herein, a simulated flue gas stream is purified by the catalytic conversion of oxygen using methane (CH ₄ ). The supported palladium (Pd) catalyst selectively reduces oxygen to an effluent gas with 99.7% CO ₂ and 0.3% O ₂ . Using a higher Pd loading has no impact on the oxygen conversion, whereas feeding excess CH ₄ decreases the selectivity to CO ₂ . A complete removal of O ₂ is achieved using a copper‐based oxygen scavenger placed after the Pd catalyst bed, yielding a 100.0% pure CO ₂ stream.

Catalytic Removal of Oxygen Impurities from Pressurized Oxy-Combustion Flue Gas for the Production of High-Purity Carbon Dioxide

Journal Article Lu, Hong ; Jiang, Ye ; Abiodun, Oki ; ... - Energy and Fuels

Flue gas purification is important for pressurized oxy-combustion systems to produce pure carbon dioxide (CO₂) streams ready for storage or utilization. A catalytic approach to removing oxygen (O₂) impurities from pressurized oxy-combustion flue gas via reduction with methane (CH₄) was investigated in this work. Two types of catalysts were studied: palladium (Pd)-based catalysts supported on titania (TiO₂) prepared by incipient wetness impregnation and cobalt–manganese (CoMn) composite catalysts prepared by coprecipitation. The performance of the catalysts was evaluated in a high-pressure–high-temperature, fixed-bed reactor at a pressure of 15 bar and a gas hourly space velocity of 30 000 h^–1 (standard conditions),more »« less

High-efficiency catalytic reduction of residual oxygen for purification of carbon dioxide streams from high-pressure oxy-combustion systems

Journal Article Lu, Hong ; Schideman, Luke ; Ye, Qing ; ... - Reaction Chemistry & Engineering

Pressurized oxy-combustion is a promising technology for carbon capture, utilization, and storage. For the captured CO₂ to be used for enhanced oil recovery or stored in geological formations, flue gas impurities, including residual O₂ in the CO₂ stream, must be purified to meet the purity specifications. A catalytic approach to reducing residual O₂ with CH₄ was investigated in this study. Five CoMn- and Cu-based catalysts were synthesized or acquired, and a reverse-flow fixed-bed reactor was used to assess their performance for O₂ removal from a simulated oxy-combustion flue gas at 15 bar. The impacts of the operating parameters on O₂more »« less

Catalytic Removal of Oxygen and Pollutants in Exhaust Gases from Pressurized Oxy-Combustors

Technical Report Lu, Yongqi ; Dastgheib, Seyed ; Lu, Hong ; ...

The primary goal of this project was to develop and validate advanced catalytic materials and systems for purifying the flue gas generated from pressurized oxy-combustors in an effort to achieve the purity specifications of carbon dioxide (CO₂) streams required by the U.S. Department of Energy (USDOE) for application in enhanced oil recovery. The technology has shown great potential for improving energy efficiency, simplifying process complexity, and lowering costs compared with current state-of-the-art oxy-combustion flue gas purification technologies. Laboratory studies were conducted for the development, characterization, and screening of metal catalysts for residual oxygen (O₂) reduction with methane (CH₄) and multifunctional carbon catalysts for combined nitrogen oxides (NO_x), sulfur oxides (SO_x), and mercury (Hg) removal. A bench-scale reverse-flow fixed-bed (RFFB) reactor and a trickle-bed direct-contact cooler (DCC) reactor capable of treating 15 standard liters per min of pressurized oxy-combustion flue gas were fabricated and tested with both a simulated flue gas in the laboratory and a slipstream of actual flue gas at a 100 kW_th Staged, Pressurized Oxy-Combustion (SPOC) pilot facility. Process simulation and techno-economic studies were performed to evaluate the energy efficiency and cost of the developed catalytic flue gas purification process integrated into a conceptual 550-MWe SPOC power plant. The goal and objectives of the project have been successfully accomplished. A cobalt-manganese (CoMn) oxide catalyst was developed and demonstrated in the bench-scale RFFB reactor in either a reverse-flow or one-direction flow mode of operation that met the success criterion of performance for residual O₂ reduction. A carbon catalyst was developed and demonstrated in the bench-scale DCC reactor that met the success criterion of performance for combined NO_x/SO_x/Hg removal. Slipstream testing of the integrated DCC-RFFB system at the SPOC pilot facility demonstrated stable operation and verified the superior performance obtained in the laboratory. The techno-economic analysis showed that a 550-MWe SPOC plant integrated with the catalytic flue gas purification process would result in costs of electricity ofmore »« less

Catalytic Reduction of Residual Oxygen for the Purification of Carbon Dioxide Streams from Pressurized Oxy-Combustors

Conference Lu, Hong ; Schideman, Luke ; Lu, Yongqi

Pressurized oxy-combustion (OC) is regarded as an energy-efficient alternative to atmospheric OC. To utilize the captured carbon dioxide (CO2) from pressurized OC for enhanced oil recovery or carbon storage in geological formations, the CO2 product stream must meet the required purity specifications. One major impurity in OC flue gases is residual O2 (e.g., 3 vol%). In this study, a catalytic approach has been investigated to remove the residual O2 through a reduction reaction with injected methane (CH4) in a reverse-flow fixed-bed (RFFB) reactor. The performance was tested for a supported copper (Cu)-based catalyst synthesized by incipient wetness impregnation and amore »« less

Selective Reduction of Oxygen on Non‐Noble Metal Copper Nanocatalysts

Journal Article Kuhn, Andrew N. ; Ma, Yanling ; Zhang, Cheng ; ... - Energy Technology

Efficient removal of molecular oxygen (O ₂ ) from flue gas is necessary to capture and utilize carbon dioxide (CO ₂ ) from fossil‐fuel sources. Herein, the catalytic reduction of O ₂ in simulated flue gases using alumina‐supported copper (Cu) nanostructures is presented. The Cu catalyst outperformed conventional palladium systems for the selectivity toward CO ₂ over carbon monoxide (CO). Varying the reactant feed ratio can lead to structural rearrangements at the surface of Cu nanoparticles, resulting in significant differences in catalytic activity. Under optimal conditions, a favorable Cu@CuO _x core‐shell structure is observed to exhibit both excellentmore »« less
