CO2 as moderator for biomass gasification

- We compared the use of CO2 + O2, H2O + O2 and N2 + O2 as gasifying agents.
- Fluidized bed of dolomitic limestone catalysed the gasification process.
- Complex gas analysis (including tar analysis) was performed.
- The highest cold gas efficiency was achieved when gasifying with CO2.
- The gasification without a moderator led to the lowest tar yield.
