Abstract

The description relates to a particularly abrasion-resistant catalyst carrier of special activated aluminum oxide. The aluminum oxide consists of either the "gamma" or the "kappa" modification and has no "delta" modification, or it consists of the "kappa" and "theta" modifications and has no "alpha" modification. Carrier catalysts which contain catalytically active metals and/or metal compounds on the abrasion-resistant carrier are especially suitable for use in fluidized bed processes.
