How could such a question arise? What kind of gasoline desulfurization device (process)?
If there’s no change, has the desulfurizer become inactive?
No change indicates that the desulfurization effect is poor.
I guess what the original poster is asking is whether the total sulfur content remains largely unchanged before and after gasoline desulfurization or hydrodesulfurization, or whether desulfurization has a significant effect after gasoline hydrotreating. :lol
That is, the total sulfur content remains largely unchanged before and after desulfurization； But why is desulfurization still necessary? ? ? ?
Catalytic cracking uses residue as the feedstock; it involves a gasoline alkaline washing sedimentation tank and a fixed-bed reactor, with activated carbon as the medium in the fixed bed
The possibility of inactivation is virtually none
Are you still using your fixed-bed reactors? After purification, does the product go to the storage area or to gasoline hydrotreating? The quality of the oil produced by this purification method no longer meets the standards

Before, it went to the tank area; now it goes for hydrogenation
