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. This investigation covers pyrolysis of both precipitated asphaltenes and an asphaltene model compound, pentadecylbenzene. Asphaltene pyrolysis includes primary reactions to its aromatic core, maltene, and gas product fractions. Components in each of these product fractions undergo secondary degradation to lighter products, gas, and presumably, char. The present results indicate that the Schucker and Keweshan asphaltene structural model is a reasonable one, and that the observed yields of pyrolysis products and product fractions can be interpreted using their hypothetical average structure.
