The manufacturing process of catalyst pellets typically involves several steps: 1. Preparation of the Active Material: This can include processes like precipitation, impregnation, or deposition. 2. Formation of Pellets: Techniques such as extrusion, pelletizing, or tableting are used to form pellets of desired shapes and sizes. 3. Activation and Sintering: The formed pellets are then activated, often through thermal treatment, which enhances their catalytic properties.
