采用热溶剂过滤法与抽提回流法(SH/T 0509—2010),分别以正庚烷和甲苯为萃取剂,对5种重油的甲苯和正庚烷不溶物的元素组成质量分数及形貌进行了分析与表征,并且对比了重油沥青质质量分数的测定数据。结果表明:在萃取剂/原料油(体积/质量比)为30∶1(以甲苯为萃取剂)或100∶1(以正庚烷为萃取剂),滤膜孔径为0.45 μm,萃取温度为80 ℃的最佳条件下,热溶剂过滤法与抽提回流法所得沥青质质量分数相当。热溶剂过滤法具有分析速度快、适用性强、准确度高的特点,实现了甲苯和正庚烷不溶物质量分数同步测定的目标。

The element composition and morphology of toluene or n-heptane insolubles obtained from 5 kinds of heavy oil with toluene and n-heptane as extracting agent using thermal solvent filtration and extraction refluxing method (SH/T 0509—2010) were analyzed and characterized. The results showed that the mass fraction of asphaltene determined by thermal solvent filtration method was very close to that determined by extraction refluxing method under the optimal conditions of the extracting agent/raw oil (volume to mass ratio) at 30∶1 (toluene as the extracting agent) or 100∶1 (n-heptane as the extracting agent), the pore size of filter membrane of 0.45 μm, and the extraction temperature at 80 ℃. Thermal solvent filtration method had the characteristics of fast analysis speed, strong applicability and high accuracy, and could simultaneously achieve the determination of the mass fraction of toluene and n-heptane insoluble .
