| titleOfInvention | Silver impregnation method for producing an ethylene oxide catalyst having enhanced catalytic ability |
| abstract | A method for producing an effective catalyst in the oxidative conversion of ethylene to ethylene oxide, including: (i) a sub-catalytic level in the range of 0.1% to 1% by weight of silver based on the weight of the support and silver The silver ions impregnate the porous refractory support and at least partially reduce the silver ions to elemental silver to produce a low-silver catalyst precursor with separated silver atoms or silver nanoparticles on the surface of the refractory support; and (ii) The weight of the carrier and silver impregnates the low-silver catalyst precursor with at least 10% by weight of the total silver amount and the catalytic amount of at least one promoting substance of silver ions, and subjects the further impregnated carrier to an elevated temperature of at least 200 ° C for complete reduction The silver ions in the carrier form elemental silver. The low-silver catalyst precursor produced in step (i) is also described in detail. A method for oxidatively converting ethylene to ethylene oxide using the catalyst produced in step (ii) is also described. |
