Gasification of Adaro, DEJ, Hunter Valley, Merit Pila and Mukah Balingian coals have been studied in a laboratory-scale, atmospheric fluidized bed gasifier using air and air-steam as fluidizing media. Determination of the producer gas compositions were conducted using Gas Chromatography. The gasification experiments were conducted at bed temperature of 600�C. The comparison of the producer gas compositions while using air and air-steam gasifying agents were conducted. Air-steam gasification had shown significant increased on the CO, CO2, CH4 and H2 contents in the producer gas compared with the air gasification.
