Abstract:
1. A process for the removal of sulfones from oxidized hydrocarbon fuels, which comprises passing an oxidized liquid hydrocarbon fuel containing sulfones and substantially no organo-sulfur compounds continuously over a fixed bed containing a modified mesoporous silica adsorbent having a pore size in the range of 26-60 Å, a BET surface area in the range of 700-950 m 2 /g and a pore volume in the range of 0.4-0.9 cm 3 /g, pre-activated at a temperature of 350° C., at a weight hourly space velocity (WHSV) in the range of 1-20 h −1 , at an adsorption temperature of 20-30° C., at one bar pressure and regenerating the adsorbent by passing an organic solvent over the fixed bed for a time period of 20 to 30 minutes for further adsorption of sulfones.
