CATALYST BED FOR THE CATALYTIC DEHYDROGENATION OF ALKANES

摘要

The invention relates to bed particles for the dehydrogenation of alkanes in a dehydrogenation reactor, the bed particles consisting of a mixture of two different particle types A and B, wherein one particle type comprises a unit of identical particles, particle type A is a catalyst containing a porous carrier and at least one active surface element, and particle B is a porous body which donates oxygen, and contains at least one oxide or a mixture of oxides NiO, NiAI2O4, CuO, Mn3O4, Fe2O3, Fe3O4, FeO, TiO2, SiO2 und CSZ, CeSZ, MSZ and YSZ, and particle type B has 0.1 to 10 times the volume of particle type A. The invention further relates to a method for the dehydrogenation of alkanes using the bed particles according to the invention.
