the mole fraction of CO in the gasification gases increased, while H2
and CO2 decreased. When CO2 mass percentage in the gasifying
agent reached 60%, the fractions of CO and CH4 attained the maximum,
as well as gas LHV and cold gas efficiency. Hanaoka et al.
[16] studied the gasification of aquatic biomass using O2/CO2 mixtures
with different proportions. The increase in CO2 content led to
the increase in the conversion to gas and enhanced CO release,
while H2 content decreased.
