STUDY ON MECHANISM OF ACTIVATED CARBON ADSORPTION FOR FUEL OIL DEEP DESULFURIZATION

Deep-desulfurization via selective adsorption is considered as one of the most promising methods since it can selectively remove organic sulfur compounds from oils under mild conditions. On the basis of induction of the composition of fuel oil and sulfur compounds, the mechanisms of activated carbon absorption for deep desulfurization of fuel oil are reviewed, including molecule size selection, acidic sites effect, complex adsorption and catalytic oxidation, and their affecting factors are discussed. Meanwhile the prospect of development of the research on adsorption desulfurization of fuel oil is predicted.
