摘　　要：以小桐子油为原料,在(40±1)℃下进行厌氧发酵试验,测定其产沼气性能。结果表明,小桐子油厌氧发酵平均产气周期为33 d,两个阶段的小桐子油平均原料产气率为286.62 mL/g,平均池容产气率为0.73 m^(3)/(m^(3)·d)。通过对发酵前后泥油热解特性分析,验证了小桐子油中长链脂肪酸被分解为小分子脂肪酸。这说明以油脂为唯一碳源仍然可以进行沼气发酵,为小桐子油的资源化利用开辟了一个有效途径。Jatropha curcas L.oil was taken as raw material to make the anaerobic fermentation at(40±1)℃,and the biogas production performance was studied.The results showed that the average biogas production cycle of J.curcas L.oil anaerobic fermentation was 33 days.The average biogas yield of J.curcas L.oil in two stages was 286.62 mL/g and the average volumetric biogas production rate was 0.73 m^(3)/(m^(3)·d).By analyzing the pyrolysis characteristics of mud oil before and after fermentation,it was verified that the long-chain fatty acids in J.curcas L.oil were decomposed into small molecular fatty acids.This indicated that the biogas fermentation could still be carried out with oil as the sole carbon source,which opened up an effective way for the utilization of J.curcas L.oil as a resource.
