It is important to understand the tar evolving and cracking behavior in the fluidized bed gasifier. With peanut shell, rice straw and saw dust as raw materials, the gasification was carried out in a pilot scale fluidized bed gasifier at variant temperatures (750℃~850℃), air equivalence ratio (0.15~0.35) and catalyst addition. Simultaneously, tar component was analyzed using gas chromatograph with mass selective detector.
