Iron oxide catalyst

Recovering useful hydrocarbons from sewage sludge using zirconia-supporting iron oxide catalysts was investigated. Zirconia has activity for decomposing water molecules to generate active oxygen and hydrogen species.

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.

Abstract A new method is presented for improving the performance of red mud as a hydrogenation catalyst (a residue from the production of alumina by the Bayer process that contains iron oxides), based on the method developed by K.C. Pratt and V. Christoverson, Fuel 61 (1982) 460. The activation method consists essentially in dissolving red mud in a mixture of aqueous hydrochloric and phosphoric acids, boiling the resulting solution, adding aqueous ammonia until pHˆ8, and ®ltering, washing, drying and calcining the resulting precipitate. ...

Abstract Red mud is a residue in the production of alumina by the Bayer process. It contains oxides of iron and titanium, and has been shown to be active in sulfided form as hydrogenation catalyst. The evolution of sulfided red mud activity and selectivity with reaction time was studied for the hydrogenation of a light fraction of an anthracene oil.
