Chemical Engineering Science, 2001 For combustion with CO2 capture, chemical-looping combustion has the advantage that no energy is lost for the separation of CO2. In chemical-looping combustion oxygen is transferred from the combustion air to the gaseous fuel by means of an oxygen ...

Plantwide control of chemical looping combustion
2012 American Control Conference (ACC), 2012Passive systems theory is used to develop a general procedure to design the control structure of chemical process networks. A natural storage function, derived from the second law of thermodynamics, is the basis for passivity-based control design. The inventory control laws are implemented locally and individual units become passive.

Geopolymer composites for chemical looping combustion
Fuel, 2018Chemical looping combustion allows a simple separation of CO2 during the combustion of fossil fuels, thanks to the use of regenerable oxygen carriers. In this work, novel materials containing manganese and iron/manganese oxides have been developed via geopolymerization, and characterized in thermogravimetric apparatus and fixed bed reactor.

Chemical looping combustion (CLC)
, 2013 Chemical-looping combustion (CLC) is a new combustion technology with inherent separation of the greenhouse gas CO2. The technology involves the use of a metal oxide as an oxygen carrier which transfers oxygen from combustion air to the fuel, and hence a

Chemical looping: To combustion and beyond
Catalysis Today, 2014Abstract Chemical looping combustion (CLC) is a rapidly emerging technology for clean combustion of fossil and renewable fuels which allows production of sequestration-ready CO 2 streams with only minor efficiency penalties for CO 2 capture. While initial interest in chemical looping was almost exclusively focused on combustion, we demonstrate here

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.

Solid fuels in chemical-looping combustion
International Journal of Greenhouse Gas Control, 2008The feasibility of using a number of different solid fuels in chemical-looping combustion (CLC) has been investigated. A laboratory fluidized bed reactor system for solid fuel, simulating a chemical-looping combustion system by exposing the sample to alternating reducing and oxidizing conditions, was used.
