General description
4,6-Dimethyldibenzothiophene (4,6-DMDBT), a high refractory sulfur compound, is commonly found in diesel fuel. Its synthesis has been reported. The hydrodesulfurization of 4,6-DMDBT using bulk nickel alloy, bulk tungsten phosphide (WP), NiMo sulfide supported on active carbons and molecularly imprinted polymers have been reported. The dielectric behavior of 4,6-DMDBT under different microwave frequencies and temperature has been investigated.

Oxidative desulfurization is considered to be one of the most promising methods for producing ultra-low-sulfur fuels because it can effectively remove refractory sulfur-containing aromatic compounds under mild conditions. In this work, the oxidative desulfurization performance over UiO-66(Zr) is greatly enhanced

Deep desulfurization is a challenging task and global efforts are focused on the development of new approaches for the reduction of sulfur-containing compounds in fuel oils. In this work, we have proposed a new design strategy for the development of
