| Abstract: | This paper aims at reviewing the mechanism of liquid-phase adsorptive desulfurization. Physical adsorptive desulfurization technology is poor in selectivity for sulfur compounds and therefore a deep desulfurization is difficult,which accurs through molecular size selection mechanism,or acidsites adsorption mechanism.The emphasis is paid on theπ-complexation adsorption mechanism and SM coordination mechanism.The opinions with respect to the future application trend of adsorptive desulfurization is assessed.The advantages of adsorptive desulfurization for fuels are attractive,such as much milder conditions,higher desulfurization efficiency,olefins being not saturated,lower investment, lower operating cost,etc.Consequently,the liquid-phase adsorption desulfurization is becoming a promising method for deep desulfurization. |
