โฆ Synopsis
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 (>350ยฐC) temperatures are attained.
