Asphaltenes isolated from coal liquids and tar sand bitumen have been converted thermally and with acid and/or hydrogenation catalysts. The conversions, based on solubility classes Ð preasphaltenes, asphaltenes and oil Ð have been determined for increasing reaction time. The removal of heteroatoms i

The thermal decomposition of Athabasca asphaltene at relatively low (<35O"C) temperatures is believed to proceed by elimination of groups situated on peripheral sites of the asphaltene. More severe degradation of the asphaltene structure does not occur until elevated (>350Β°C) temperatures are attain
