Abstract
A non-oxidized diesel desulfurization process that uses temperature swing adsorption along with an adsorbent to adsorb sulfur compounds and other impurities petroleum-based from fuel compositions, including light distillates, middle distillates, diesel, gasoline and transmix. The process uses temperature cycling of an adsorbent bed to adsorb and desorb organosulfur compounds and other impurities. Once the adsorbent reaches a selected concentration of sulfur compounds, the temperature of the adsorbent bed is raised to desorb sulfur compounds, using a regenerant.
