  • Spherical zeolitic catalyst for converting methanol into olefins
    Patent number: 9511361
    Abstract: A catalyst containing a pentasil-type alumosilicates and a binder, in the form of spheres having an average diameter between 0.3 and 7 mm, wherein the BET surface area of the catalyst ranges from 300 to 600 m2/g. Also disclosed is a method for producing the catalyst, wherein primary crystallites of the aluminosilicate having an average diameter of at least 0.01 ?m and less than 0.1 ?m are mixed with the binder, shaped into spheres having an average diameter between 0.3 and 7 mm, and subsequently calcined. Also disclosed is the use of the catalyst for converting methanol into olefins, in particular propylene. Also disclosed is a method for producing olefins from methanol, in which a feed gas is fed across the catalyst.
