LAYERED COMPOSITE AND METHOD OF MAKING AND USING SAID COMPOSITE Russian patent published in 2009 - IPC B01J37/25 B01J23/44 B01J23/52 B01J23/46 C07C67/55 

FIELD: chemistry.

SUBSTANCE: invention relates to a layered composite, method of making and method of converting hydrocarbons using said composite. A layered composite is described for catalytic production of alkenyl alkanoates, containing an inner core and an outer layer, which contains heat-resistant inorganic oxide, a fibrous component, inorganic binder and palladium, gold or their mixture as the catalytic component, dispersed in the outer layer. A method is described for production of alkenyl alkanoates, involving bringing a mixture of alkene, alkanecarboxylic acid and oxygen-containing gas into contact with the catalyst described above. A method is also described for making a catalyst for production of alkenylalkanoate, involving coating an inner core with a suspension, containing an outer heat-resistant inorganic oxide, fibrous component, inorganic binder precursor, organic binder and solvent, so as to obtain a core with an outer coating layer, and baking at temperature below 200°C for a period of time sufficient for binding the outer layer to the inner core, so as to obtain a layered composite, which contains a catalytic component containing palladium, rhodium, gold or their combination.

EFFECT: obtaining high-strength catalyst.
