Direct use of CO2 instead of steam or as a partial substitute for steam in coal and biomass direct gasification processes is one of possibilities of potential useful application of CO2. Based on the above stated facts we concentrated in our study on FB gasification of COS and COWS slurries with gases containing higher concentrations of CO2. Our attention was particularly devoted to effects of CO2 concentrations and gasification temperature on producer gas heating value, energy yield, tar and BTX yields in comparison with FB gasification with steam-O2 mixtures.
