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.

Scale-Up of Chemical Looping Combustion
2014The use of chemical looping combustion (CLC) for power generation is a possible pathway to meet demands for developing clean and efficient fossil fuel-based energy systems. CLC is an advanced technology that captures CO2 inherently and could prove to be an advantageous next electricity generation technology in a carbon-constrained energy scenario ...
