Decrease the catalyst’s activity D. Prevent excessive temperature and rapid deactivation during the initial stage of catalyst operation
D. Prevent excessive temperature rise and rapid deactivation during the initial activation phase of the catalyst. The catalyst has high activity after sulfidation; stabilizing this initial activity is also referred to as passivation. By appropriately reducing the activity, it is possible to avoid issues such as excessive temperature rise that can occur during the early stages of production due to high activity, thereby extending the catalyst’s lifespan
The purpose of stabilizing the initial activity of hydrogenation catalysts is (D, to prevent excessive temperature rise and rapid deactivation during the initial activation stage of the catalysts).
