Katalizátorregeneráció
Katalizátorregeneráció refers to the process of restoring the effectiveness of a catalyst that has lost its activity over time. Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. In many industrial applications, such as in chemical manufacturing or automotive exhaust systems, catalysts degrade due to fouling, poisoning, or sintering. Fouling occurs when unwanted materials deposit on the catalyst surface, blocking active sites. Poisoning involves the chemical adsorption of impurities onto the catalyst, permanently deactivating it. Sintering is the agglomeration of catalyst particles at high temperatures, leading to a reduction in surface area.
Regeneration aims to reverse these deactivation mechanisms. Common regeneration methods include thermal treatment, where the catalyst
The success of regeneration depends on the type of catalyst, the deactivation mechanism, and the severity of
