Situations in which catalyst regeneration is necessary: 7. Catalyst regeneration: 8. Criteria for evaluating the performance of regenerated catalysts: 9. Why is it necessary to dry catalysts? 10. How to select the sulfiding oil during catalyst pre-sulfidization? 11. Criteria for completing sulfidization: 12. Purpose and location of adding desalinated water in hydrogenation processes. 13. What is the impact of pressure on diesel hydrofining? 14. What is the impact of the properties of crude oil on hydrofining? 15. Differences in crude oils: 16. Treatment of crude oil: 17. Key points for operating crude oil buffer tanks: 18. Pressure control in the reaction system: 19. In which areas is hydrogen used in hydrofining? 20. Regulation of the reaction feed rate: 21. What are the hazards of too low a feed rate to the plant? 22. What are the reasons for the decrease in bed temperature and how to address it? 22. Control of the temperature in the cold high-pressure section: 23. Control of the liquid level in the cold high-pressure section: 24. Control of the interface level in the cold high-pressure section: 25. Regulation of the purity of circulating hydrogen: 26. Role of circulating hydrogen. 27.
