摘　　要：对比研究生物航煤在不同储存条件下微生物生长的情况,以及微生物污染对生物航煤理化性能指标的影响。试验表明:生物航煤在储存过程中混入水,储存温度在30℃~35℃范围时,易滋生微生物;微生物污染对生物航煤的FAME、总酸值、实际胶质影响较明显,对密度、粘度影响较小。The microorganism growth under different storage conditions and the influence of microbial contamination on the physicochemical indicators of bio-fuel were studied by using bio-fuel,jet fuel and mixed fuel samples.The analysis of data show that,there was alsOmicrobial contamination in the bio-fuel mixing with the water during the 30~35℃storage condition.The microbial contamination had a significant effect on FAME,total acid value and existent gum,and had less effect on density and viscosity.
