Laboratory, electrically heated gasifier with fluidized bed (FB) of sand particles was used for the gasification with steam-O2 and CO2-O2 mixtures (ER = 0.19 – 0.23) at temperatures between 800 and 925 °C. FB gasification with mixtures of O2/CO2 can generate producer gas with heating values (LHV) about 8 - 10 MJ/m3. The LHV values of the producer gas are influenced by relatively high content of methane, ethylene and BTX compounds. The yield of heavier tar compounds (excluding BTX) is high, exceeding 20 g tar/kg of dry German coal based COS and 36 g/kg of fuel for Polish coal based COS. FB gasification of the COWS prepared from the Polish coal with 40 mass % of water and 12 mass % of oil by steam–O2 and CO2-O2 mixtures (ER =0.20) reduces tar yield approx. to an half.
