摘　　要：在下落式管式炉上研究两种惰性气氛(N2和CO2)对生物质热解产率和液体产物的影响,测定不同气氛下的快速热解和催化热解(HZSM-5为催化剂)的产率,并利用气质联用仪(GC/MS)分析热解油的成分。研究表明,改变热解气氛对结果产生明显影响。CO2对快速热解和催化热解均有不利影响,导致液体产率降低而固定碳和结焦产率上升,热解油的成分复杂化,抑制热解过程的芳香环化反应,使产物结构中出现甲氧基支链,同时在催化热解中促进稠环芳烃的生成。Influences of two inert atmospheres, N2 and CO2, on pyrolysis yields and oil products were studied by using a drop-tube furnace. The yields of fast pyrolysis and catalytic pyrolysis were recorded and oil products were analyzed on GC/MS. The results showed that changing the pyrolysis atmosphere has apparent influence on result. Carbon dioxide has a harmful influence on both fast and catalytic pyrolysis, such as reducing the liquid yield and increasing the solid yield and coke on bed material. Moreover, it inhibits aromatic cyclization reaction and causes producing methoxy branched-chains and polycyclic aromatic hydrocarbon in pyrolysis procedure.
