The microwave technology was introduced to separate naphthenic acids from diesel fuel. The decrease of zeta-potential of electric double layer on the W/O interface and the reduction of diesel fuel viscosity were responsible for the accelerated separation of naphthenic acids under microwave irradiation. The influences of dosage of alkali compound solvent (Mp / MT), irradiation pressure, irradiation time, irradiation power, the settling time and oil phase-to-solvent phase volume ratio (O/S) had been investigated. The optimum process conditions for the refining process were determined. The removal of naphthenic acids reached 98.4% when the optimum conditions were proposed as follows: Mp/MT=1 .5,0.05MPa, 6 min, 375W, 25min and O/S=10, respectively. The diesel recovery could reach 99.3% and the quality of the treated diesel oil was good enough to meet the specification of GB252-2000.
