Stabilizers function through various mechanisms to protect the catalyst. Some common methods include:
- Preventing Aggregation: Stabilizers can prevent the agglomeration of catalyst particles, which otherwise reduces the active surface area. - Inhibiting Sintering: They help to maintain the dispersion of catalyst particles, preventing them from sintering at high temperatures. - Reducing Poisoning: Stabilizers can also protect catalysts from being poisoned by impurities or reaction by-products.
