煤直接液化柴油的储存安全性

Storage Stability of Direct Coal Liquefaction Diesel

通过对比实验,对煤直接液化柴油的储存安定性进行了考察,结果表明,经过加氢改质的煤直接液化柴油有很好的储存安定性,其氧化安定性(总不溶物)、色度、10%蒸余物残炭在储存6个月后仍远小于国家《轻柴油》标准规定的指标。此外,煤直接液化柴油的储存安定性好于对比的石油基柴油。石油基柴油掺入煤直接液化柴油后,安定性可得到一定改善。煤直接液化柴油性质稳定,密度、馏程等不随储存时间的变化而发生改变。

Results of comparasion experiments show that hydrogenated direct coal liquefaction diesel is quite stable for storage.The oxidation stability (total insoluble substance),chroma and 10% carbon residue on residuum are much less than national standard of Light Diesel after stored for 6 months.What s more,the diesel from direct coal liquefaction is stabler than petroleum-based diesel for storage.When they are mixed,the fuel is safer.The density and distillation range of diesel from direct coal liquefaction do n...
