  • Process for the removal of sulfones from oxidized hydrocarbon fuels
    Patent number: 8562821
    Abstract: Described herein 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.
    Type: Grant
    Filed: December 9, 2009
    Date of Patent: October 22, 2013
    Assignees: Council of Scientific & Industrial Research Center for High Technology, Ministry of Petroleum & Natural Gas
