在石油工业中，人们希望从未使用的重油中生产轻质烃，如汽油、煤油和瓦斯油。为此，我们研制了氧化锆负载氧化铁催化剂（ZrO_2-FeO_3催化剂），用于水蒸气分解石油渣油（常压渣油）。此外，我们还发现，在ZrO_2-FeO_x催化剂中引入Al_2 O_3可以有效地提高催化剂的活性和稳定性。考察了氧化铁基催化剂中Al 2 O3和ZrO 2含量对催化剂活性和稳定性的影响。并将该催化剂用于减压渣油和奥里油等特稠油的裂解。在ZrO_2-Al_2O_3-FeO_3催化剂上，水蒸气作用下，超稠油得到了有效的裂解，轻烃收率达60%以上
In petroleum industry, it is desirable to produce lighter hydrocarbons such as gasoline, kerosene and gas–oil from unused heavy oils. Thus we have developed zirconia-supporting iron oxide catalysts (ZrO2–FeOXcatalyst) to decompose petroleum residual oil (atmospheric distilled residual oil) with steam. In addition, we have found that the incorporation of Al2O3among FeOXcrystals is effective in improving the catalytic activity and stability of the ZrO2–FeOXcatalyst. In this study, the effects of Al2O3and ZrO2content in FeOX–based catalysts on catalytic activity and stability were investigated. Furthermore, the FeOX–based catalyst was applied to the decomposition of extra heavy oils such as vacuum distilled residual oil and Orimulsion. These extra heavy oils were effectively decomposed over the ZrO2–Al2O3–FeOXcatalyst with steam, and the yields of lighter hydrocarbon reached to above 60%
