| titleOfInvention | Calcination in inert gas in presence of low-concentration oxidising component |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to an improved method of producing silver catalysts used in gas phase synthesis of ethylene oxide from ethylene and oxygen. Described is a method of producing a catalyst, involving saturation of an inert substrate with a solution which contains a catalytically effective amount of a compound which contains silver, a promoting amount of a compound which contains a transition metal, calcination of the saturated substrate by heating at temperature ranging from approximately 200°C to approximately 600°C for a period of time sufficient for reducing the silver compound to metallic silver, and for decomposition and removal of almost all organic substances; heating is carried out in an atmosphere which includes a combination of an inert gas and from approximately 10 parts per million to approximately 500 parts per million of a gas which contains an oxygen-containing oxidising component. The invention describes a catalyst produced using said method, and a method of oxidising ethylene to ethylene oxide using molecular oxygen in gaseous phase in the presence of the obtained catalyst in a fixed layer in a tubular reactor. n EFFECT: improved catalyst activity and selectivity. n 25 cl, 1 ex, 1 dwg |
