    Gasification, one of the thermo-chemical conversion technologies, has been known and researched for the conversion of low graded solid feedstock to gaseous form of fuel. Gasification for obtaining high-valued combustible gas such as hydrogen and carbon monoxide has been focused again due to high oil price with needs of alternative energy. And the gaseous product, known as synthesis gas (syngas) can be effectively utilized in a variety of ways ranging from electricity production to chemical industry. Gasification and melting processes are also operated at high temperatures with the destruction of hazardous components and production of gases, mainly CO and H2, which can be utilized as fuel gas or raw chemicals after cleaning. In this study, sawdust was experimented on in a lab-scale gasification process in order to characterize the gaseous products. At isothermal conditions at a fixed temperatures (800, 1000, 1200oC), the concentrations of CO, H2 and CH4 increased but CO2 and N2 decreased with lower equivalent ratio (ER). C2H6 concentration was varying and not depending upon ER. Carbon conversion efficiency, gas and tar yields increased with increasing ERs. Tar yield was related to carbon conversion efficiency and gas yield.
