Chemical Looping Combustion for Power Production
2015The post-combustion technologies generally consist of chemical absorption systems that are operated at almost atmospheric pressure and with amine-based solvent. One of the most promising technologies is chemical looping combustion (CLC): the conversion is performed by using a solid metal (called oxygen carrier), which is alternatively oxidized and ...

Solution combustion synthesized oxygen carriers for chemical looping combustion
Chemical Engineering Science, 2007Abstract Chemical looping combustion is an attractive method for CO 2 capture in power plants, while maintaining high energy efficiency. The cyclic nature of the process, however, places significant demands on the redox and mechanical characteristics of the oxygen carrier.

Chemical-Looping Combustion for Combined Cycles With CO2 Capture
Volume 7: Turbo Expo 2004, 2004Chemical-Looping Combustion (CLC) is a process where fuel oxidation is carried out through an intermediate agent — a metal oxide — circulated across two fluidized bed reactors: a reduction reactor, where an endothermic reaction reduces the metal oxide and oxidizes the fuel, and an oxidation reactor, where an exothermic reaction oxidizes the metal oxide

A Thermodynamic Analysis of Chemical Looping Combustion
Volume 4: Cycle Innovations; Fans and Blowers; Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Marine; Oil and Gas Applications, 2011Recently, interest has grown in chemical looping combustion (CLC) because it is seen as a technique that may allow cost-effective carbon capture and storage (CCS). In CLC the overall reaction by which chemical energy is released is between a hydrocarbon and air as in conventional combustors.

Chemical Looping Combustion: Status and Development Challenges
Energy & Fuels, 2020Because the CO2 capture is inherent in chemical looping combustion (CLC), thus ideally avoiding costly gas separation, this process has potential for uniquely low costs of CO2 capture. The review reports on operational experiences with different oxygen carriers in CLC pilot operation.

Exergy analysis of chemical-looping combustion systems
Energy Conversion and Management, 1998A power plant based on chemical-looping combustion offers both a possibility of high net power efficiency and separation of the greenhouse gas CO2. This is due to the way the oxidation of the fuel takes place. Instead of oxidizing the fuel with oxygen from the combustion air, the fuel is oxidized by an oxygen carrier, i.e., an oxygen-containing ...

Fundamental insights into chemical looping combustion (CLC)
2018<p>This work aims to develop fundamental insights about the underlying surface and bulk chemical processes instrumental to the efficiency of chemical looping combustion (CLC). CLC, which uses a solid-state oxygen carrier (e.g., metal oxides) to drive hydrocarbon combustion, is a promising combustion alternative that minimizes byproduct formation ...
