乙醇柴油的储存稳定性研究

介绍了对乙醇柴油的相溶性、低温稳定性、自然储存稳定性进行的研究工作.以相分离温度来评价乙醇柴油的相溶性,结果显示在乙醇体积分数低于10%时,乙醇柴油的相分离温度基本不变,乙醇含量增大,相分离温度升高;在乙醇体积分数为50%时,相分离温度为最大值.加入助溶剂能明显增强乙醇柴油的相溶性并延长低温稳定时间.自然储存试验结果显示,乙醇柴油密封储存三个月没有明显的乙醇溶解不均匀或分层现象,储罐内各个位置油样中乙醇含量和水含量基本保持稳定.乙醇柴油开口储存导致乙醇含量和水含量发生变化,最后趋于稳定.     

氧含量和压力对柴油自燃行为的影响

在定容燃烧弹系统上，研究了柴油在不同氧含量和不同压力条件下的喷射自燃行为。采用十六烷值改进剂硝酸异辛酯(EHN)、含氧组分聚甲氧基二甲醚(DMMn)和高密度燃料(HDF)与基础柴油复配，研究了不同复配柴油的十六烷值特性和在不同压力下的燃烧特性。结果表明：氧含量和压力的下降会使柴油的着火滞后期和燃烧滞后期延长，燃烧滞后期对氧含量的敏感性大于压力的变化；当压力下降时，柴油燃烧的压力升高最大值会降低；当氧含量下降时，在一定压力范围内压力升高最大值会随氧含量下降而升高；复配柴油的燃烧滞后期和动态十六烷值对压力变化的敏感性与柴油的组成密切相关。柴油热值严重影响燃烧的压力升高值，通过加大喷油量可有效提高压力升高最大值。
