Carrier treatment to improve catalytic performance of an ethylene oxide catalyst |
| abstract |
Methods are provided for varying the level of sodium as well as reducing the sodium content of different carriers, which may have different physical properties. The method for reducing the sodium content from the surface and the lower surface as well as the binding layer of the carrier includes contacting the carrier with water. The cleaning solution is recovered from the contact. The cleaning solution contains sodium leached from the carrier. Then, the sodium content in the cleaning solution is measured. The contacting, recovery and measurement are repeated until a certain state is achieved in the sodium content. |
