| 摘 要： | 采用裂解气相色谱(PY-GC)方法研究重油中的大分子硫化物。实验考察了裂解时间和裂解温度对裂解反应的影响,在此基础上确定了裂解色谱条件,并分析了渣油裂解产物的组成。通过对大港、俄罗斯、前郭、孤岛及俄罗斯-大庆混合减压渣油等5种渣油的裂解实验,发现不同来源的渣油裂解产物中硫化物的组成和含量存在较大差异。实验中所得到的裂解产物中硫化物的组成为渣油中硫化物的组成提供了重要信息。

| Abstract: | Flash pyrolysis-gas chromatography has been used to investigate macromolecular sulphur in heavy oil. The influences of pyrolysis time and pyrolysis temperature have been studied and the analytical methods of pyrolysis were set up. Sulfur-containing products were identified by comparing with reference data and semi-quantified by a pulsed flame photometric detector (PFPD). The investigation conducted on Dagang, Gudao, Qianguo, Russia and mixed Russia-Daqing residual oils using pyrolysis-gas chromatography showed that the contents and composition of sulphur compounds demonstrated various characters in different pyrolysates of residual oils. |
