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.

为了了解生物质流化床气化过程中焦油的析出和脱除特性，以花生壳、稻草以及木屑为原料，采用流化床气化反应系统，研究了气化温度(750℃~850℃)、空气当量系数(0.15~0.35)以及催化剂（白云石、橄榄石与菱镁矿）的添加等对气体产物中焦油的析出组成特性的影响，并采用色谱-质谱联用仪对焦油的主要成分进行了分析。
