Activity of Ru-Fe2O3 catalysts in the process of NO reduction with propane

The activity of supported ruthenium catalysts (Ru/Fe2O3) in the reaction of NO reduction with propane was studied. The iron oxides used as support of the ruthenium phase differed only in the type of oxidehydroxide (α-, β-, γ-, δ-FeOOH) used in synthesis of the support. It has been established that the precursor Fe2O3 determined the activity of the catalysts studied in the process of NO reduction with propane. It has been shown that the catalysts Ru/Fe2O3 precipitated on the properly prepared iron oxide permit obtaining high NO conversion at temperatures from 400 to 500oC in reducing conditions.
