摘要: A silver impregnation solution containing: (i) silver ions, (ii) a polar organic additive containing two to four carbon atoms and two to four functional groups selected from hydroxy, carboxylic acid, and amine groups, provided that a carboxylic acid group can only be present along with a hydroxy or amine group, and provided that an amine group can only be present along with a hydroxy or carboxylic acid group; and (iii) water; wherein components (i) and (ii) are water soluble and dissolved in the impregnation solution. Also described herein is a method for producing a catalyst effective in the oxidative conversion of ethylene to ethylene oxide, the method comprising subjecting a refractory carrier impregnated with the above-described silver impregnation solution to a calcination process. Also described herein is a method for converting ethylene to ethylene oxide by use of the foregoing silver catalyst, as produced by the above-described silver impregnation solution.

摘要: A supported silver catalyst and use thereof in a process for producing an alkylene oxide, such as ethylene oxide, by the direct oxidation of an alkylene with oxygen or an oxygen-containing gas, wherein the catalyst provides improved stability and improved resilience to reactor upsets and timely recovery to substantially pre-upset levels of catalyst activity and/or efficiency. In some embodiments, the catalyst also exhibits improved activity. A catalyst capable of producing ethylene oxide at a selectivity of at least 87 percent while achieving a work rate of at least 184 kg/h/m3 at a temperature of no greater than 235° C. when operated in a process where the inlet feed to a reactor containing the catalyst comprises ethylene, oxygen, and carbon dioxide, wherein the concentration of carbon dioxide in the inlet feed is greater than or equal to 2 mole percent.
