Zirconia-including iron catalyst with high durability was successfully prepared which had high activity for recovering lighter fuels from petroleum residual oil in a steam atmosphere. Zirconia dispersed highly in iron catalyst supplied enough amount of active oxygen species from steam into iron oxide lattice. Lattice oxygen in iron oxide reacted with heavy oil. Thus, oxidative cracking of heavy oil with steam was accelerated over iron catalyst with highly dispersed zirconia without any lack of lattice oxygen of iron oxide.
