Abstract:

The study examines the impact of CO2-rich atmospheres on the gasification of poultry litter (PL). Experiments were conducted with CO2 concentrations ranging from YCO2 = 0.10 to 0.30, and under pyrolysis conditions in pure N2 for comparison. Beech wood (BW) chips were used as a reference fuel. All samples were pelletized before the process. Key parameters such as gas composition (CO, CH4, H2), maximum lower heating value (LHVmax,) cold gas efficiency (CGE), and carbon conversion (Cconv) were evaluated. Results showed that higher CO2 levels improved syngas quality for poultry litter, with maximum CGE (82.08%) and LHVmax (2.25 MJ/m³) at YCO2 = 0.30. However, these values were lower than for BW (CGE = 90.11%; LHV = 5.01 MJ/m³), likely due to high ash content in PL, limiting the fixed carbon conversion. The findings confirm the potential of CO2-assisted gasification for low-quality biomass.
