Chemical-looping gasification (CLG) of biomass for fuel production
Research Project, 2017
– 2019
In this project chemical-looping gasification (CLG) of biomass will be evaluated and developed for production of syngas (H2/CO) and subsequent synthesis of biofuels. CLG is built around the same principles as indirect gasification, with two interconnected fluidized beds – air reactor and fuel reactor/gasifier – but uses an oxygen carrier, instead of sand, as bed material. This could have important advantages as compared to normal indirect gasification: i) a more oxidizing environment and the presence of oxygen carriers in the gasifier reduces tar formation, and ii) the cost of gas cleaning is reduced, as essentially all the fuel is converted in the fuel reactor, and none in the air reactor, thus reducing the total volume of gas needing clean-up. In this application the CLG process is made more cost-effective by using waste materials from the steel industry as oxygen carriers. Experimental investigations up to 100 kW are complemented with a techno-economic evaluation of the process.
