Hidropricing katalizátorok, tipically concenting nickel and mold mold um, can deactivate due to coking and metal deposition. A plant employedd thermal and chemical regeneratiool methods, including controlled oxidatiod and acid washing, to restie catalyst activity. These technokes efectively removed coke and meta meta meta contaminants, allowing the catalyste catalysto bis, interesto, interests, tu.

Key Takeaws

  • Catalyst deactivation is of ten caused by coke, small metals, or poisons.
  • Regeneration methods include oxidative burning, chemical cleaning, and re- sulfiding.
  • Proper regeneration extends catalyst life and d maintains process effecenciy.
  • Monitoring feastock quality can reduce catalyst poisoning risks.
