Amorphotheca resinae对喷气燃料影响试验研究

Experimental Study on Effects of Amorphotheca resinae on Jet Fuel

在一组油-水体系中接种喷气燃料特征真菌Amorphotheca resinae进行培养,另一组油-水体系作为空白对照,研究Amorphotheca resinae大量繁殖后对喷气燃料理化性能的影响。试验表明:喷气燃料的外观、颗粒度、水分离指数、酸值等受Amorphotheca resinae影响明显,密度、水反应、闪点、冰点等受影响较小。同时,该真菌的存在加剧了油罐的腐蚀,特别是界面生物膜的腐蚀更为严重。

In order to study the influence of Amorphotheca resinae on jet fuel’s physicochemical indexes, two oil-water sys-tems were established, in one of which Amorphotheca resinae was cultivated. Then jet fuel’s indexes in the two systems were com-pared. And the result shows that the physicochemical properties of jet fuel, such as the appearance, particle size, water separation in-dex and acid, changed obviously, but water reaction, density, flash point and freezing point were almost stable. It was also concluded that the fungus was exacerbated in the presence of oil tank corrosion, especially the corrosion in interface biofilm.
