Sulfur reduction catalyst
Thread Content
In response to the recent issue of high sulfur content in gasoline, our company has made adjustments at the operational level, including controlling the mixing of raw materials, regulating the top temperature during distillation, and improving the desulfurization efficiency. In addition, we have also added certain desulfurization additives. I would like to ask everyone: what is the principle of action of current desulfurization catalysts? Should sulfur be removed or transferred? Because recently our acidic water sulfides have risen again
How does the mechanism of action of current sulfur-reduction catalysts work? Should sulfur be removed or transferred? Recently, the levels of sulfides in our acidic water have risen again. The mechanism of action of the current sulfur-reduction catalysts is primarily based on adsorption reactions; they function as desulfurizing agents rather than catalysts. The reason for the increase in acidic water sulfides again is: 1. The desulfurization efficiency of the hydrogenation unit has increased, leading to an increase in acidic water sulfides ； ⒉Regarding the enhanced stripping effect in the fractionation tower, the formation of acidic water sulfides also increases. That’s when the situation seen by the original poster occurred.
I’m sorry, boss – I didn’t explain clearly. We are catalytic devices
Is there no more detailed and professional explanation?:'
A desulfurization catalyst, also known as a sulfur transfer catalyst, is a catalytic cracking catalyst that transfers SOx from flue gas into the reactor where it is converted into H2S. Sulfur should be transferred rather than removed. It is estimated that sulfides are transferred to the distillation tower in order to prevent dew point corrosion in the flue gas engines and boilers.
There are generally two types of catalytic desulfurization agents: sulfur transfer catalysts (solid) and desulfurization additives (liquid). Both work by converting sulfur into elemental sulfur, and this process can typically reduce sulfur levels by 10-20%. The increase in acidic water sulfides you mentioned is a sign of an increase in hydrogen sulfide resulting from the presence of elemental sulfur.
Sulfur has moved to the distillation section; an increase in acidic water is normal.
