Selective chemical decomposition, IR spectroscopy, and high-resolution mass spectrometry were used to study the composition of structural fragments linked through sulfur bridges in the asphaltene components of heavy fuel oil as well as the products of its thermal and thermocatalytic cracking. Pyrolysis in the presence of initiators derived from fly ash ferrospheres leads to more extensive changes in the structure of the asphaltene components.
