Adsorptive desulfurization relies on the principle of adsorption, where sulfur compounds are captured on the surface of a solid adsorbent. The process typically involves the following steps: 1. Contacting the fuel with an adsorbent. 2. Adsorption of sulfur compounds onto the adsorbent surface. 3. Separation of the adsorbent containing sulfur compounds from the desulfurized fuel. 4. Regeneration of the adsorbent for reuse, which involves removing the adsorbed sulfur compounds.
