Adsorptive desulfurization of diesel by regenerable nickel based adsorbents

► NiMCM-41 and NiY were demonstrated as regenerable diesel sulphur adsorbent. ► Sulphur level was brought down to below 50 ppm from a 450 ppm 'S' refinery diesel. ► The process conditions are milder in comparison to conventional HDS processes. ► The H2 requirement of the present process is also lower than conventional processes. ► Adsorbent regeneration conditions were optimized based on TPO study.
