N2 - Pyrolysis experiments with Off-shore Californian-, Mayan-, Jobo-, Athabascan-, and Hondo- derived asphaltenes were performed to probe the effect of asphaltene origin on reaction kinetics. For each feedstock the kinetically significant pathways were asphaltene reaction to coke, asphaltene to maltene, maltene to gas, and asphaltene to gas. First-order and second-order reaction models thowed similar trends, with the relative error between model and data being lower than 0.25. A model based on 'easy' and 'hard' kinetic lumps improved the model fit to a relative error of less than 0.06. The feedstock dependence of these results is discussed.
