Liaohe 超重的原油被分开成它的部件,也就是浸透, aromatics,树脂,和沥青质(SARA ) ,由组分离方法。几溶剂被用来从原油提取金属性的元素的不同形式。金属性的元素例如钙,镍,铁和锰,被诱导地联合的血浆在原油, SARA 和摘录样品分析原子排放光谱学(ICP-AES ) 。结果证明钙,镍,铁,和锰的内容逐渐地增加在浸透, aromatics,树脂,和沥青质,建议许多在沥青质的四个金属性的元素在另外的组比那高得多。例如,在沥青质的钙的内容到达 7,920 g/g 的最大值。在 Liaohe 超重的原油的 SARA 部件之中,树脂说明超过 50 wt% ,建议四个金属性的元素的全部的数量在比在另外的部件的树脂部件是更高的。四个金属性的元素主要在原油在器官的金属性的混合物形式存在。钙和锰元素主要作为石油酸的金属盐存在的进一步的分析表演,和铁和所有镍的多数主要作为 metalloporphyrin 和 non-metalloporphyrin 混合物存在。
Liaohe super-heavy crude oil was separated into its components, namely saturates, aromatics, resins, and asphaltenes (SARA), by the group separation method. Several solvents were used to extract different forms of metallic elements from crude oil. The metallic elements, such as calcium, nickel, iron and manganese, in crude oil, SARA and extract samples were analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The results demonstrate that the contents of calcium, nickel, iron, and manganese gradually increase in saturates, aromatics, resins, and asphaltenes, suggesting that the abundance of the four metallic elements in asphaltenes is much higher than that in the other groups. For example, the content of calcium in asphaltenes reaches a maximum of 7,920 pg/g. Among the SARA components of Liaohe super-heavy crude oil, resins account for more than 50 wt%, suggesting that the total amount of the four metallic elements are higher in the resin component than in other components. The four metallic elements mainly exist in the form of organic metallic compounds in crude oil. Further analysis shows that calcium and manganese elements exist mainly as metal salts of petroleum acids, and the majority of the iron and all the nickel exist mainly as metalloporphyrin and non-metalloporphyrin compounds.
