Product refining desulfurization

There is likely no similar technology available at the moment; if S-zorb technology is taken into account, levels can be reduced to below 10 ppm.
We have carried out some projects on gasoline desulfurization by extraction, and the results have been good. First, cut it; then extract sulfur from medium gasoline through hydrodesulfurization, and remove sulfur from heavy gasoline via hydrogenation
It’s a pretty good way to handle it. What are the sulfur content and the approximate composition of sulfides in heavy oil?
Is there anyone who can tell me the latest developments in current oil desulfurization technologies? ! Thank you! ! !
Pure adsorption has not been used for the desulfurization of gasoline and diesel; what has been used is the conversion of sulfur, with various methods employed for separation, or the conversion of sulfur into a stable form, such as disulfides. When disulfides are present in gasoline, the total sulfur content in the gasoline remains unchanged, but the level of mercaptan sulfur can be reduced to less than 10 ppm.
The refinement of gasoline and diesel does not involve simply desulfurizing them; especially for diesel, desulfurization alone is not sufficient, as other parameters also need to meet the required standards. Are you a non-standard oil blending supplier? Refining companies still can’t do without hydrogenation!
I’m just looking for a desulfurization method that requires low investment, does not involve hydrogenation, and has low treatment costs. I wonder if there is such a “good thing”
Yes. But theoretically, is such a thing possible?
