Basics
- Often abbreviated as CLC
- A form of Oxy-Fuel Combustion Process technology using metal oxides as the oxygen source, thus air never contacts the combustion chamber thus making the formation of nitrogen dioxides near impossible
- Assuming the fuel used is either pure carbon, or methane, there should be no heavy metals or hydrogen sulphide as well
- Uses a Fluidized Bed Gassifier for syngas production, then Fluidized Bed Reactor with the metal oxide as a sort of air free burner
- This also lowers the total flue gas volume, and makes the composition near pure carbon dioxide and water vapor
- The water vapor can be condensed leaving near pure carbon dioxide
- RESEARCH NEEDED
- The mechanism of transfer between fluidised beds
- If NOx is produced and how much
- What oxides to use and if they need a substrate etc
- Pollution/Tar Issues?

- The Wikipedia Page on Chemical Looping Combustion
- AN Article on CLC this is aimed twards coal, and the website covers many non-renewable resources, so possible bias (although they do cover biomass and other renewables as well)
- A Research Paper on Carrier Oxide Development
- A Research Paper on CLC
- A A University of Iowa Article on the Subject
- A Paper on a 10 (thermal) kilowatt biomass clc reactor, using iron oxide as a carrier
- Meant for coal, seemed to seperate gassification, and CLC?
