Chemical-looping gasification for production of aviation fuel with negative emissions

Chemical-looping gasification (CLG) of biomas is an efficient method for production of jet fuel with negative emissions. CLG is autothermal and part of the feed is oxidized to CO2 to fulfill the heat balance. However, the CO2 is concentrated only in the fuel reactor and can easily be captured and stored.

In this project, Chalmers in cooperation with Boliden will investigate CLG with negative emissions tailored for bio-jet fuel production. This will include experiments at different scales and process modeling to develop an efficient process. Various biogenic residues will be studied with “Järnsand” (copper smelter slag) as an oxygen carrier.

Järnsand is the main waste material from copper production industry and is mostly landfilled.

However, Järnsand is a very promising OC candidate for CLG and the metal oxide content should be optimal for high syngas yield.

The integration of by-products from industry with CLG could result in resource and energy efficient production of aviation fuel.
