2-17　石炭ガス化に及ぼすプラスチック粉末混合の影響

抄録

Central Research Institute of Electric Power Industry is developing a polygeneration system with CO₂ capture consisting of an O₂/CO₂/H₂O blown gasifier that uses various fuels such as coal, waste plastic and biomass. We investigated the effect of adding plastic to coal on gasification performance experimentally using 3t/d coal research gasifier. It was confirmed that gasifier carbon conversion efficiency increased and cold gas efficiency nearly unchanged under the same oxygen ratio. It is considered that cold gas efficiency can be improved by adjusting the oxygen ratio. And it was found that the char of 1 µm or less increases due to the increase in volatile matter in the fuel.
