| 摘 要： | 测定了中东常压渣油加入正庚烷后的电导率，并计算得到了不同正庚烷加入量时的质量分数电导率值。结果表明，渣油质量分数电导率的最大值可以看作是用正庚烷稀释时沥青质聚沉的发生点。采用离心法和光学显微镜观测法探讨了中东常压渣油用正庚烷稀释时沥青质聚沉的发生，结果与质量分数电导率法研究一致。

| Abstract: | The electrical conductivity of Middle East Atmospheric Residue (ME-AR) diluted by n-heptane was continuously measured, and the mass fraction normalized conductivity of ME-AR was calculated. The maximum value of the calculated mass fraction normalized conductivity of ME-AR was found to be the mark of the occurrence of asphaltene precipitation. Both the results of gra- vimetric analysis and microscopy observation supported this conclusion. |
