Performance of Cu- and Fe-based oxygen carriers in a 500 Wth CLC unit for sour gas combustion with high H2S content

- CLC burnt sour gas with CO2 capture without any sweetening pre-treatment unit.
- Sour gas with H2S contents up to 15 vol% have been used.
- Copper sulfides formation prevents the use of copper-based materials.
- Fe20γAl oxygen carrier is adequate for sour gas combustion with high H2S contents.
