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