摘要
本文系用六组分分离法对我国12种原油减压渣油中镍、氮及残炭分布的情况进行研究.数据表明,我国减压渣油中的镍95%以上存在于其胶质沥青质中,其分布一般呈双峰形,除戊烷沥青质中镍含量最高外,另在重芳烃或轻胶质中有一次高值.氮的含量约有70～90%存在于其胶质沥青质中,其分布比较均匀.减压渣油的残炭中约有90%是由其中的胶质沥青质所形成的,它与H/C比之间具有密切的联系.
The distribution of Ni, N and carbon residue among the six fractions of the vacuum residues of 12 Chinese crude oils has been studied. The data obtained show that the Ni reveals a bimodal distribution pattern with a maximum at pentane asphaltene and a second extreme value at heavy aromatic or light resin fraction, and 95% of the Ni is present in the resin-asphaltene fraction. It is also found that 70～90% of N is contained in resin-asphaltene fraction and it is rather well-distribution. Besides, the carbon residue of vacuum residue is mainly contributed by its resin-asphaltene, and is closely related to the H/C ratio of the fractions.
