Abstract (en)

[origin: WO2012140614A1] The invention relates to a method for producing a catalyst used for oxidizing ethylene to obtain ethylene oxide, comprising the steps of a) providing a carrier that has a temperature T0, contains aluminum oxide, and is impregnated with silver or a compound containing silver; and b) heating the impregnated carrier from temperature T0 to a temperature T1 at a minimum heating rate of 30 K/min. The invention also relates to the catalyst obtained using said method.
