PP-II-32Insertion in structure of the catalyst of compounds of cerium or molybdenum results inincrease of selectivity of the process (up to 88-91%) at rather small growth of activity.Probably it is connected with formation of solid solutions, for example Се 2 О 3 in iron(III)oxide.Fe-Cr-O sample shows rather low selectivity in contrast to activity of oxide compounds,at slight increase of conversion.Synthesized Fe-K-Ce and Fe-K-Mo compounds, and also synthesized on the base of thesecompounds four-component systems has conversion of 72-76 % and selectivity of 92-93 %,that is at a level of domestic and foreign dehydrogenation catalysts tested in simulatedcondition.References1.
