A new strategy for the conversion of heavy oil components into chemical feedstocks and fuels is proposed. First, alkyl polycyclic aromatic hydrocarbons in heavy oils are dealkylated to long-chain alkanes and polycyclic aromatic hydrocarbons without substituents. This allows the separation of oil components into alkanes (aliphatic hydrocarbons) and aromatic hydrocarbons. Since polycyclic aromatic hydrocarbons have limited applications, combination of partial hydrogenation and ring-opening can be used to convert them to benzene derivatives to increase the yield of chemical feedstocks. In this lecture, these strategies will be presented together with experimental results.
