What is the purpose of passivating a hydrogenation reactor? () A. To extend the catalyst’s service life B. To prevent the spontaneous combustion of ferrous sulfide C. To delay the carbon deposition on the catalyst’s surface D. To avoid poisoning of the catalyst’s surface by hydrogen sulfide. What is the passivation reaction equation for CO/MO biphasic hydrogenation catalysts?
What is the purpose of passivating the hydrogenation reactor? (a)
A. Prolonging the catalyst’s service life: When a hydrorefining unit is put into operation, sulfur is first injected to carry out pre-sulfidization of the catalyst. Purpose: The high initial activity of the catalyst is reduced through presulfurization, thereby enhancing the catalyst’s service life and stability.
