In this study, white pellets are gasified in a fixed-bed gasifier, using air as the gasification agent. Experiments were conducted at 1atm, 4atm, and 8atm. Temperature of five points inside the gasifier were measured and product gas distribution was analyzed during the experiments. Until now, CO2 has been produced much more than in the ideal gasification condition. Produced gas composition changed periodically, and continued to change in a certain range for hours. In a pressurized condition, H_2/CO ratio showed to increasing tendency.
