Abstract: The paper presents the demetallization from Liaohe coker gasoline under the ultrasound radiation. The effect of ultrasound-assisted, demetallization agent and its amount, reaction time in demetallization were studied, in order to obtain optimum processing parameter during demetallization. The results show that high metal removal effect will be obtained in short time under the assistance of ultrasound. The metal removal effect is the best when the demetallization agent [KG*3/5]mass[KG*3/5] fraction[KG*3/5] is 1 500 μg/g, the ultrasound radiation time is 15 min and the ultrasound intensity is 8 W/cm2. The removal rate of Zn is 90%, and the removal rates of Ca and Ni are above 80%.
