摘要: Process for the conversion of non-oxidative coupling of methane to ethylene, under non-oxidative conditions, comprising: providing a first stream containing at least 50 vol. % of methane based on the total volume of said first stream; providing a catalyst; putting in contact said first stream with said catalyst at a weight hour space velocity ranging from 0.5 to 100 h−1, a temperature ranging from 500° C. to 1100° C. and a pressure ranging from 0.1 MPa to 5 Mpa in the absence of oxygen; recovering a second stream containing unconverted methane if any, ethylene and hydrocarbons having at least 2 carbon atoms. Said process is remarkable in that said catalyst is a synthetic zeolite material, containing at least one metal M with silicon to metal M molar ratio Si/M as determined by inductively coupled plasma optical emission spectrometry ranging from 100 to 65440 and in that said metal M is incorporated inside of the zeolite tetrahedral sites.

摘要: The present disclosure relates to a novel method for introducing various metals in the structure of zeolite frameworks by isomorphous substitution. This new method is based on a hydrothermal reaction of the metal with the zeolite. This method allows obtaining zeolite with a structure and with control of the metal location.

摘要: The present disclosure relates to a novel staged-synthesis method for introduction of various metals in the structure of zeolite frameworks by isomorphous substitution. This new method is based on a hydrothermal synthesis in which the metal addition to the precursor suspensions (gel) is delayed. This so-called “staged-synthesis method” allows to obtain nanosized silanol highly homo-geneous crystalline zeolite structures with a control of the metal location.

摘要: Catalyst compositions comprising an inorganic porous material with pore diameters of at least 2 nm and of crystals of molecular sieve, characterized in that the crystals of molecular sieve have an average diameter, measured by scanning electron microscopy, not bigger than 50 nm, and in that the catalyst composition presents a concentration of acid sites ranges from 50 to 1200 μmol/g measured by TPD NH3 adsorption; and the XRD pattern of said catalyst composition is the same as the X ray diffraction pattern of said inorganic porous material.

摘要: A catalyst composition contains an inorganic porous material with pore diameters of at least 2 nm and of crystals of molecular sieve. The crystals of molecular sieve have an average diameter, measured by scanning electron microscopy, not bigger than 50 nm. The catalyst composition has a concentration of acid sites ranges from 50 to 1200 μmol/g measured by TPD NH3 adsorption. An XRD pattern of the catalyst composition is the same as an XRD pattern of the inorganic porous material.
