Thread Content
Generally, when sulfiding a hydrogenation catalyst, once the H2S partial pressure in the recycle hydrogen reaches a certain value, the sulfidation rate no longer increases. Generally, when the H2S concentration in the circulating hydrogen reaches (), the sulfur injection rate can be appropriately reduced. A. 0.5% B. 1.0% C. 2.0% D. 3.0% B
Generally, when sulfiding a hydrogenation catalyst, once the H2S partial pressure in the recycle hydrogen reaches a certain value, the sulfidation rate no longer increases. Generally, when the H2S concentration in the circulating hydrogen reaches (B), the sulfur injection rate can be appropriately reduced.
Generally, when the H2S concentration in the circulating hydrogen reaches (B), the sulfur injection rate can be appropriately reduced.
B, 1.0%------------------------------------------------------------------
Generally, when sulfiding a hydrogenation catalyst, once the H2S partial pressure in the recycle hydrogen reaches a certain value, the sulfidation rate no longer increases. Generally, when the H2S concentration in the circulating hydrogen reaches (B 1%), the sulfur injection rate can be appropriately reduced.
The answer is C; it is generally between 0.2% and 2%
