PARTIAL GASIFICATION OF DIFFERENT TYPES OF COALS IN A FLUIDISED BED GASIFIER
Keywords:
Coal, fluidized bed, gasification, air, steamAbstract
Partial gasification of Adaro, Dasa Eka Jasatama (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. Partial gasification experiments were conducted at bed
temperature of 60rtC. The comparison of the producer gas compositions while
using air and air-steam gasifying agents were conducted. Introduction of steam
had shown significant increased on the CO, CO2, CH4 and H2 contents in the
producer gas compared with the air as the sole gasifying agent.
