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.

Catalyst containing phosphorus for converting oxygenates into olefins

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.

Process of producing zeolite-based catalysts for converting oxygenates to lower olefins

The present invention relates to a process for preparing a phosphorus containing zeolite type catalysts based on crystalline aluminosilicates, the catalysts of this process and the use of this catalysts for the conversion of methanol to olefins.

Process for manufacture of a zeolite based catalyst for the conversion of methanol to olefins

The present invention relates to a process for preparing phosphorus containing zeolite type catalysts based on crystalline aluminosilicates, the catalysts of this process and the use of these catalysts for the conversion of methanol to olefins.

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 m/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 &#x3bc;m and less than 0.1 &#x3bc;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.

Spherical zeolitic catalyst for converting methanol into olefins

The invention relates to a method for purifying wastewater loaded with nitrogen-containing compounds, wherein the wastewater loaded with nitrogen-containing compounds is reacted with a smectic sheet silicate, wherein a clay material loaded with nitrogen-containing compounds is obtained, and the clay material loaded with nitrogen-containing compounds is separated off, wherein purified wastewater is obtained.
