Abstract:

Oxidation desulfurization via photocatalysis was investigated by using thiophene in xylol as the model compound, and hydrogen peroxide is used as the oxidant. The effects of hydrogen peroxide mass fraction, high shear agitation time, titanium dioxide mass on the desulfurization efficiency of FCC gasoline were also investigated. Under suitable conditions, the desulfurization rate of the model compound and of FCC gasoline can reach 80% and 59%, respectively. The conductivity and GC-FPD analyses show that the sulfurcontaining compounds are converted into the substance with a higher polarity.

Key words: FCC gasoline; Model; Photocatalysis; Oxidation;
