Recently, the demand for useful fuels such as gasoline and kerosene has grown every year and approximately half of the primitive petroleum deposits have already been consumed. Therefore, new techniques to produce the fuels from unused heavy oils such as atomospheric- or vacuum-distilled residual oils, oil sand, and Orinoco tar are required. Especially, the deposit of Oil sand and Orinoco tar are larger than that of the petroleum deposit. Thus, we have developed zirconia, alumina, and iron oxide composite catalyst (ZrO_2-Al_2O_3-FeO_x catalyst) to decompose petroleum residual oil with steam. In this article, we introduce the production of lighter fuels from the heavy oil and extra heavy oil with steam using ZrO_2-Al_2O_3-FeO_x catalyst, and effects of the content of Al_2O_3 and ZrO_2 content in ZrO_2-Al_2O_3-FeO_x catalyst on catalytic activity and stability are investigated.
