title: [Analysis of composition and structure of sulfur compounds in residual oils by pyrolysis-gas chromatography].
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.
