摘　　要：在亚临界及超临界条件下 (T=40 0℃～ 50 0℃ ,P=2 5.3～ 30 .4MPa) ,在间歇式、连续式反应器中研究了温度、压力、停留时间对苯酚去除率的影响。发现在其他条件不变的情况下 ,随反应温度和压力的升高、停留时间的延长 ,苯酚的去除率提高 ;在很短的停留时间内 ,苯酚的去除率可达 96 %以上。The factors which affected the destruction of phenol in subcritical and supercritical water were investigated in a batch reactor and a continuous flow reactor at temperature from 400 ℃ to 500 ℃,pressure from 25 3 MPa to 30 4 MPa.The results showed that the increase of the temperature,pressure and resident time would promote the removal efficiency of phenol with other conditions unchanged.The removal efficiency of phenol could be achieved 96 % in a short time.The intermedium products in liquid could demonstrate the completeness of the oxidation.
