The research to diesel super intensive desulfurization through oxidative extraction undertaken by Academician Li Can from CAS Dalian Research Institute of Chemistry and Physics has made a major breakthrough and applied for two invention patents in China.
A high-effect hydrophilic/ oleophilic catalyst is assembled on the oil/water interface. Hydrogen peroxide is used in mild conditions to turn sulfur-containing molecules in diesel into sulfone through selective oxidation. An appropriate extracting agent is then used to extract sulfone. The sulfur content in diesel can there fore be reduced from around (5 X [10.sup.-4]) to less than (1 X [10.sup.-5]). In optimal ...
