Abstract

Catalyst deactivation is a common problem in chemical engineering, affecting reaction efficiency and product quality. The causes of catalyst deactivation are complex and diverse, mainly including poisoning, sintering, contamination, and mechanical wear, etc. A deactivated catalyst not only reduces the reaction rate but also may lead to resource waste and environmental pollution. Therefore, it is particularly important to study the regeneration technology of catalysts. Common catalyst regeneration methods include high-temperature regeneration, chemical reduction, cleaning, and removal, etc. This article mainly explores the main causes of catalyst deactivation and related regeneration technologies, analyzes their application effects and limitations, aiming to provide a theoretical basis and practical guidance for catalyst management in the chemical industry. By optimizing the regeneration technology, it is expected to extend the service life of catalysts, improve resource utilization efficiency, and reduce the environmental burden.
