“…Oxy-combustion would seem a good alternative, given that high-concentration CO 2 is obtained in the gases. However, the oxygen required for the process must be produced in an air-separation unit, also highly energy-demanding . CLC reaction occurs with a lower irreversibility compared to a conventional combustion, leading to a somewhat higher overall thermal efficiency …”

“…The sorbents in this case are derived from cheap, abundant, and environmentally benign limestone and dolomite, and the process imposes a relatively small efficiency penalty on the power/industrial process (i.e., estimated to be 6–8%, compared to 9.5–12.5% from amine-based post-combustion capture). CLC was proposed to have a relatively high energetic efficiency in integrated power generation with inherent CO 2 separation. − Alvaro et al carried out simulations to evaluate the energetic efficiency of the CLC-based power plant under diverse working conditions. A comparison of a conventional integrated gasification power plant with pre-combustion capture of CO 2 has been made.…”

CO₂ Capture with Chemical Looping Combustion of Gaseous Fuels: An Overview

The world-wide consumption of natural gas (NG) and other fossil fuels (e.g., coal and crude oil) is ever increasing. However, most CO 2 resulting from either NG combustion or other processes is released into the atmosphere without capture. Chemical looping combustion (CLC) is a two-step combustion technology for power and heat generation with inherent CO 2 capture, using either gaseous fuels or solid and liquid fuels. A previous review focused on CLC of solid fuels or CLC of all types of fuels but did not give an in-depth and specific discussion of gaseous fuel CLC systems. China is one of the largest consumers of NG, coal, and crude oil in the world, and it is essential to develop an alternative technology to take the place of gaseous fuel (e.g., NG) combustion. This Review summarizes recent research and development work on CLC using gaseous fuels, including a technological and economic assessment, types of oxygen carriers (OCs), reactor types, coke formation and OCs poisoning, efficiency and exergy analyses, and model development based on a literature survey. The plant efficiency of NG-CLC can be up to 52−60% (LHV), including CO 2 compression, based on calculations and simulations, which is about 3−5% more efficient than a NG combined cycle with CO 2 capture. Ni-based materials have been widely developed and applied for NG-CLC because of its fast kinetics for methane conversion. CuO−Cu 2 O/Cu, Mn 3 O 4 −MnO, and Fe 2 O 3 −Fe 3 O 4 are typical OCs with high selectivity toward CO 2 and H 2 O. The operating conditions are closely dependent on reactor configurations, hydrodynamics, mass and heat balances, and characteristics of the OCs in the system. CLC and other CO 2 capture technologies are also compared in the present Review, which has rarely been investigated previously. From simulation and process analysis, a conceptual design of a NG-CLC power plant of thermal input 655 MW th is conducted to clarify its technological advantages and economic benefits compared to other power generation processes. The air reactor, fuel reactor, and OCs do not impose significant economic barriers for scale-up and commercialization of CLC.

Chemical looping combustion of solid biomass has the unique potential to generate energy with negative carbon emissions, while entailing an energy penalty compared to traditional combustion that is lower than that of the competing carbon capture technologies. In spite of these attractive features, research is still needed to bring the technology to a fully commercial level. The reason relies on a number of technological challenges mostly related to the oxygen carrier performance, its possible detrimental interaction with the biomass ash components, and the efficiency of the gas–solid contact with the biomass volatiles. This review is focused on these specific challenges which are particularly relevant when firing biomass rather than coal in a solid-based chemical looping combustion process. Special attention will be given to the most recent findings published on these aspects. Related performance evaluation by modeling, system integration, and techno-economic analysis will also be briefly reviewed.

Metal-organic frameworks (MOFs), a new family of porous materials, have received great attention over the past several decades as potential materials for gas separation and storage, and drug delivery. However, the widespread use of these materials has been seriously hampered by their susceptibility to moisture, which impacts their sorption properties. Here, we explored the sorption properties of a titanium-oxo cluster that can maintain sorption properties in a humid environment for CO 2 capture and H 2 purification using Monte Carlo (MC) simulations and density functional theory (DFT). The CO 2 , N 2 , CH 4 , and H 2 gas-sorption properties of the titanium-oxo cluster were investigated using by comparing sorption site and binding energies, demonstrating that the titanium-oxo cluster can be utilized as a CO 2 separator and H 2 purification. The comparison between MC and DFT calculations reveals that atomistic MC simulation is particularly useful in the investigation of the sorption behavior of such a complex material.
