The high shear agitation device was first adopted for gasoline desulfurization by ionic liquids. The effect of benzylimidazol fluoborate in desulfurization of gasoline and the influence of moisture on deuslfurization rate were investigated. The experimental results showed that the ionic liquid could effectively decrease the sulfur content of gasoline and the optimal conditions were as follows: The reaction could be carried out at room temperature, a volumetric ratio between oil and the liquid of 2:1, a volumetric ratio between water and ionic liquid of 0.04:1, a rotational speed of 5 krad/s, and a reaction time of 1 minute. The desulfurization rate of gasoline reached 53.6%, and the gasoline yield was up to 97.3%. The ionic liquid could be recycled for repeated use, and the use of high shear agitation for gasoline would have good prospects.

Thiophene (C4H4S) and 3-methylthiophene(3-MC4H4S) are typical thiophenenic sulfur compounds that exist in fluid catalytic cracking (FCC) gasoline. Oxidation of C4H4S and 3-MC4H4S were conducted in hydrogen peroxide (H2O2) and formic acid system over a series of silica gel loaded with metal oxide. The silica gel loaded with copper and cobalt (1:1) oxide was found very active for the model compound oxidation using H2O2/formic acid, while the silica gel unloaded with metal oxide was less active. The sulfur removal rate of thiophenes was different as solvent was changed. And the conversation of C4H4S and 3-MC4H4S was improved at higher temperature,but reduced when olefin was added. The sulfur removal rate of model sulfur compounds was enhanced when the phase transfer catalyst emulsifier polyethylene glycol octyl phenyl ether or tetrabutylammonium bromide(TBAB)in a H2O2 and formic acid system with the addition of TBAB, a bromine substitution trend appeared in the oxidation of thiophenes, suggesting the influence of TBAB.

A simulated gasoline consisting of model sulfur compounds of thiophene （C4H4S） and 3-methythiophene （3-MC4H4S） dissolved in n-heptane was tested for the oxidative desulfurization in the hydrogen peroxide （H202） and formic acid oxidative system over metal oxide-loaded molecular sieve. The effects of the oxidative system, loaded metal oxides, phase transfer catalyst, the addition of olefin and aromatics on sulfur removal were investigated in details. The results showed that the sulfur removal rate of simulated gasoline in the H202/formic acid system was higher than in other oxidative systems. The cerium oxide-loaded molecular sieve was found very active catalyst for oxidation of simulated gasoline in this system. The sulfur removal rates of C4H4S and 3-MC4H4S were enhanced when phase transfer catalyst （PTC） was added. However, the sulfur removal rate of simulated gasoline was reduced with the addition of olefin and aromatics.
