Abstract

The thermal decomposition of Athabasca asphaltene at relatively low (<350° 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 (>350° C.) temperatures are attained.
