With the increasing environmental consideration and stricter regulations, gasification of waste is considered to be more attractive technology than conventional incineration for energy recovery as well as material recycling. The experiment for combustible waste mixed with plastic and cellulosic materials was performed in the fixed bed gasifier to investigate the gasification behavior with the operating conditions. Waste palletized with a diameter of 30mm and 50mm of length was gasified at the temperature range of 1100~1450℃. It was shown that the composition of H2 was in the range of 30~40% and CO 15~30% depending upon oxygen/waste ratio. Gasification of waste due to thermoplastic property from mixed plastic melting and thermal cracking shows a prominent difference from that of coal or coke. It was desirable to maintain the top temperature up to 400℃ to ensure the mass transfer and uniform reaction through the packed bed. As the bed height was increased, the formation of H2 and CO was increased whilst CO2 decreased by the char-CO2 reaction and plastic cracking. From the experimental results, the cold gas efficiency was around 61% and heating values of product gases were in the range of 2800~3200kcal/Nm3.
