How Do Impregnation Methods Affect Catalyst Properties?
The method of impregnation can determine how well the active component is distributed on the support. Common methods include:
- Wet Impregnation: Soaking the support in a solution containing the active component, followed by drying and calcination. - Dry Impregnation: Mixing the support with a minimal amount of solution, leading to a more uniform distribution. - Co-precipitation: Simultaneously precipitating the support and active component from a solution, resulting in intimate mixing.
