Is there any process for desulfurization and aromatization of solvent oil that does not require hydrogenation? Please tell me something. . . .
I have heard of two processes: molecular sieve adsorption and sulfonation. . . My unit does not have this device, so it is not a good comment. Please continue to participate. . . :lol
For dearomatization, solvents with high solubility selectivity for aromatic hydrocarbons can be used for removal, such as furfural and sulfolane.
At present, the most effective method is dearomatization through hydrogenation process, but the investment is huge. Several other adsorption methods, extraction methods and sulfonation methods are only introduced in literature and patents, and there are no specific application devices yet.
Desulfurization is widely used in Shandong, and it is basically a catalyst adsorption method. In fact, it is a strong acid and alkali oxidation method.
