研究了超声波作用下石油焦中铁等杂质元素的浸出。考察了酸种类、浸出时间、液固比、酸浓度、反应温度、超声功率和频率等因素对浸出率的影响。已经发现，在所研究的酸中，盐酸具有最大的去除效率。当浸出时间为35 min、液固比为10 ml/g、酸浓度为12 wt%、反应温度为50 °C、超声功率为240 W、超声频率为80 kHz时，铁的去除率最高。与传统的搅拌法相比，去除效率显著提高。通过扫描电镜分析了超声波辅助脱除石油焦中杂质的机理。
In the present study, iron and other impurities element leaching from petroleum coke in the presence of ultrasound were investigated. The parameters investigated were the different types of acid, leaching time, liquid–solid ratio, acid concentration, reaction temperature, ultrasound power and frequency. It has been found that the hydrochloric acid has the largest removal efficiency among the acids investigated. The maximum iron removal rate can be reached at the leaching time of 35 min, liquid–solid ratio of 10 ml/g, acid concentration of 12 wt%, reaction temperature of 50 °C, ultrasound power of 240 W and ultrasound frequency of 80 kHz. The removal efficiency increases considerably, compared to conventional stirring method. The mechanism of removal impurity from petroleum coke with ultrasound-assisted was analyzed through SEM results.
