US8562821: Process for the removal of sulfones from oxidized hydrocarbon fuels

The invention is a process for the removal of sulfones by mesoporous silica adsorbents having narrow pore size distribution which could be controlled to specification for the selective removal of sulfones from oxidized hydrocarbon fuels wherein the sulfones were present due to oxidative conversion of organo-sulfur compounds by a suitable oxidizing solution. The mesoporous adsorbents showed typically 2-18 times higher equilibrium loading capacity for sulfones in comparison to the commercially available adsorbents.
