摘　　要：利用裂解—气相色谱质谱联用(Py-GC/MS)分析技术测定了稻壳裂解液体产物组分的种类及含量,探索了催化剂CaO、FeO和Fe2O3对稻壳高温裂解液体产物的影响。结果表明,与纯稻壳相比,添加催化剂CaO、FeO和Fe2O3后,所有样品的裂解液体产物总量都有所减少,分别下降了13.25%、19.93%和28.13%;其中,CaO和Fe2O3分别对于苯及衍生物和苯酚类物质的催化转化具有显著的促进作用,各减少了50.94%和39.75%,而FeO的加入使得产物中醛酮类质量分数增加了16.14%。Py-GC /MS analysis technology is applied to determine the category and content of liquid products obtained by pyrolysis of rice husk. The influences of catalysts（ calcium oxide,ferrous oxide and iron oxide） on liquid products from high temperature pyrolysis are investigated. It indicates that the total yield of all pyrolysis liquid products decreases by 13. 25%,19. 93% and 28. 13%,respectively,by addition of calcium oxide,ferrous oxide and iron oxide compared with the raw rice husk. Calcium oxide and iron oxide can significantly improve the catalytic conversion of benzene and its derivatives,and phenols by 50. 94% and 39. 75%,respectively. In contrast,ferrous oxide increases the aldoketones yield by 16. 14%.
