摘　　要：为了提高己二酸生产过程中产生的副产物醇酮焦油的利用率,利用水力空化技术提高醇酮焦油中≤160℃轻质组分的含量,通过单因素实验分别考察了温度、入口压力、V(甲醇)∶V(水)、pH值和循环时间对醇酮焦油轻质化的影响。在单因素实验的基础上,增加正交试验优化确定入口压力、循环时间、V(甲醇)∶V(水)对醇酮焦油轻质化的影响,当温度为80℃、入口压力为2.5 MPa、V(甲醇)∶V(水)为1.0∶1.0、pH值为4和循环时间为70 min时,≤160℃馏分变化百分率为37.62%。同时,对水力空化过程中的能量利用进行了计算,当入口压力为2.5 MPa、循环时间为70 min时,耗散实际能量所用的总能量为5.78×10^(6)kJ·m^(-3)。In order to improve the utilization rate of alcohol ketone tar,which was a by-product in the production of adipic acid,in this study,hydrodynamic cavitation technology was used to increase the content of light components in alcohol-ketone tar at≤160℃.The effects of temperature,inlet pressure,V(methanol)∶V(water)mixed content,pH and cycle time on the lightweight of alcohol-ketone tar were investigated by single factor experiments.On the basis of single factor experiments,orthogonal experiments were used to determine the optimal operation conditions.When the temperature is 80℃,the inlet pressure is 2.5 MPa,the mixed content of V(methanol)∶V(water)is 1.0∶1.0,the pH is 4,and the cycle time is 70 min,the percentage change of fractions at≤160℃is 37.62%.In addition,the energy utilization in the process of hydraulic cavitation was calculated.When the inlet pressure is 2.5 MPa,the cycle time is 70 min,the total energy used to dissipate the actual energy is 5.78×10^(6)kJ·m^(-3).
