摘要
采用nC9、nC10的混合物作为渣油模拟蒸馏的内标物,利用石科院提供的软件,进行渣油色谱模拟蒸馏测试,实验结果表明,用nC9、nC10的混合物作为渣油模拟蒸馏的内标物是可行的,相对标准偏差小于1.29%。从整个馏程看出,用色谱模拟蒸馏方法测定渣油,可以指导工艺渣油生产过程,提高轻油收率。
With the software provided by research institute of petroleum processing, a gas chromatographic simulated distillation method for the determination of distribution of residual oil fraction is described. Results showed that the nC9 ＆ nC10 mixtures could be used as internal standard. The RSD is lower than 1.29%. This method can be used to direct the process of residual oil distillation and to promote the yield of light oil.
