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.

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.

Method for processing waste water loaded with nitrogen-containing compounds

A single stage process for desulfurization and ring opening of a sulphur containing hydrocarbon feedstock comprising:

Ring opening process

Large crystal zeolites are prepared by heating a zeolite synthesis mixture under agitation to a temperature equal to or less than the effective nucleation temperature of the zeolite synthesis mixture and thereafter the zeolite synthesis mixture is heated without agitation to a temperature equal to or greater than the effective nucleation temperature of the zeolite synthesis mixture.

Synthesis of large crystal zeolites

A catalyst based on crystalline aluminosilicates of the pentasil type, having an Si/Al atomic ratio of at least 10, has the structure of primary crystallites of a mean diameter of at least 0.1 micron and at most 0.9 micron, which crystallites are partially combined into agglomerates the primary crystallites and/or agglomerates being mutually joined by finely disperse alumina obtainable by hydrolysis of aluminum-organic compounds, the BET surface area of the catalyst being 300 to 600 m.sup.2 /g and its pore volume (determined by mercury porosimetry) being 0.3 to 0.8 cm.sup.3 /g.

Catalyst based on crystalline aluminosilicate

A catalyst for the steam reforming of hydrocarbons contains nickel on an alumina/calcium aluminate support which is doped with 0.2 to 10 percent by weight of titanium dioxide. The titanium dioxide has the effect that the calcium aluminate is at least partially in the form of a hibonite [CaO(Al.sub.2 O.sub.3).sub.6 ] phase in an .alpha.-Al.sub.2 O.sub.3 matrix as defined by x-ray diffractometry.
