  • Catalyst containing phosphorus for converting oxygenates into olefins
    Patent number: 10293333
    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.

  • Process of producing zeolite-based catalysts for converting oxygenates to lower olefins
    Patent number: 10252250
    Abstract: A process of producing a catalyst based on pentasil-type crystalline aluminosilicate is described, including the steps of (a) treating hydrous aluminum oxide with an aqueous, acid-containing medium, (b) mixing the hydrous aluminum oxide treated with aqueous, acid-containing medium from step (a) with an H-zeolite and (c) calcining the mixture obtained in step (b). In addition, a catalyst is disclosed which is obtained by such a process, as well as its use in CMO and OTO processes.
