Thermal regeneration of the metal organic frameworks used in the adsorption of refractory organosulfur compounds from liquid fuels

► The thermal regeneration of C300 is only partial; some molecules remain retained. ► The crystallinity of the C300 decreases with the amount of adsorbed compound. ► Two sulfur adsorbed species have been detected by XPS, S(II) and S(VI). ► After the first regeneration the adsorption capacity drops dramatically. ► Further adsorption/regeneration cycles yields no changes in adsorption capacity.
