The industrial trend toward processing comparatively refractory heavy crudes and residua that can contain appreciable portions (10%-30%) of asphaltenes assures interest in their thermolysis. Most previous pyrolyses of asphaltenes have been oriented toward either elucidation of their structure or the identification of fragmentation products and the dependence of their yields on pyrolysis temperature. Pyrolysis kinetics related to global product fractions (e. g. asphaltene, maltene, coke) have also been reported. Little information exists, however, about the variation of the yields of the individual constituents of the product fractions with both time and temperature. Further, operative thermolysis mechanisms, e. g. pericyclic or free-radical, are obscured in the complexities of the reactions of actual asphaltenes. The foregoing motivated the present investigation of the pyrolysis of both precipitated asphaltenes and an asphaltene model compound, pentadecylbenzene.
