Abstract
The present invention relates to a novel process for preparing a phosphorus-containing catalyst, in which a steam treatment of the catalyst is effected, and to the catalyst obtainable thereby, and to the use thereof in a process for preparing olefins from oxygenates. The steam treatment of the catalyst typically precedes modification of the catalyst with a phosphorus compound.
