Abstract
A simulated gasoline consisting of model sulfur compounds of thiophene(C4H4S) and 3-methythiophene(3-MC4H4S) and n-heptane as solvent was employed for the oxidative desulfurization test in hydrogen peroxide (H2O2) and formic acid oxidative system over cerium- loaded molecular sieve. The effects of oxidative system, loaded metals, phase transfer catalyst, the addition of olefin and aromatics on sulfur removal were investigated in detail. The results showed that the sulfur removal rate of simulated gasoline in H2O2/ formic acid system was higher than the other oxidative system. The cerium-loaded molecular sieve was very active catalyst for oxidation of simulated gasoline in H2O2/ formic acid system, while the copper- and nickel-loaded molecular sieve was less active. The cobalt-loaded molecular sieve was the least active catalyst for the oxidation reaction. The sulfur removal rates of C4H4S and 3-MC4H4S were enhanced when phase transfer catalyst emulsifier OP or tetrabutylammonium bromide (TBAB) was added. However, the sulfur removal rate of simulated gasoline was reduced with the addition of olefin and aromatics. |
