TAILIEUCHUNG - Recovery of useful lighter fuels from petroleum residual oil by oxidative cracking with steam using iron oxide catalyst

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 View the MathML source to decompose petroleum residual oil (atmospheric distilled residual oil) with steam. | Chemical Engineering Science 65 2010 60-65 Contents lists available at ScienceDirect Chemical Engineering Science journal homepage locate ces Recovery of useful lighter fuels from petroleum residual oil by oxidative cracking with steam using iron oxide catalyst Satoshi Funai Eri Fumoto Teruoki Tago Takao Masuda Division of Chemical System Engineering Graduate School of Engineering Hokkaido University Sapporo 060-8628 Japan ARTICLE INFO ABSTRACT Article history Received 10 July 2008 Received in revised form 28 February 2009 Accepted 17 March 2009 Available online 26 March 2009 Keywords Catalytic cracking Iron oxide catalyst Heavy oil Oxidative decomposition Petroleum Residual oil 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-FeOx catalyst to decompose petroleum residual oil atmospheric distilled residual oil with steam. In addition we have found that the incorporation of Al2O3 among FeOx crystals is effective in improving the catalytic activity and stability of the ZrO2-FeOx catalyst. In this study the effects of Al2O3 and ZrO2 content 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-FeOx catalyst with steam and the yields of lighter hydrocarbon reached to above 60 2009 Elsevier Ltd. All rights reserved. 1. Introduction Recently the demand for useful fuels such as gasoline and kerosene has grown every year. According to the BP Statistical Review of World Energy approximately half of the primitive petroleum deposits have already been consumed. Therefore new techniques to produce fuels from unused heavy oils such as atomospheric or vacuum distilled residual .
