摘要：A novel, practical and inexpensive method has been used for treating tributyl phosphate. In this study, gasification of tributyl phosphate in supercritical water (SCW) was investigated in a reactor at 600 degrees C, 36 MPa, residence time of 600-3600 s and K2CO3 catalyst (100 -300 mg/L). The results showed that K2CO3 addition and increasing the temperature increased H-2 fraction. The precipitated alkali in the reactor still showed high catalytic effect on the subsequent gasification of tributyl phosphate without further alkali addition. The supercritical water gasification ( SCWG) of tributyl phosphate and a set of related reaction products were investigated in batch reactors by varying the temperature (T, 540-600 degrees C), time (t, 30-60 min), (H2O2 dose, 3000-6000 mg/L). The COD removal efficiency increased significantly as the H2O2 dose increased, whereas this effect was very limited at high H2O2 dose (> 4000 mg/L).
