Ru/Fe2O3 catalysts in n-butanol conversion

The activity of iron oxides prepared by different methods and ruthenium cat alysts supported on these iron oxides was studied in n-butanol conversion. A correlation between the susceptibility to reduction and the acid-base pro perties of the supports, prepared from iron oxide-hydroxides of alpha-, bet a- gamma- and 6-FeOOH types, and their selectivity in the reaction of n-but anol conversion was found. Deposition of ruthenium on the selected supports led to obtaining catalysts of enhanced activity and selectivity towards al dehyde or ester. (C) 2001 Elsevier Science B.V. All rights reserved.
