Experiment Study on Treating Tributyl Phosphate by Supercritical Water Oxidation
摘要
Abstract
Tributyl phosphate (TBP) is a typical kind of radioactive organic waste , proper treatment of w hich is very important to the sustainable development of nuclear industry .A batch type equipment of supercritical water oxiadation (SCWO) was estab‐lished to explore the oxygenolysis of TBP .The results show that the degradation prod‐ucts of TBP do not contain hazardous matters ,with CO2 in gas phase while CO2 -3 ,PO3 -4 and unreacted organics in liquid phase ,confirming the feasibility of processing TBP by SCWO technology .The effects of reaction temperature ,pressure ,and other factors on the decomposition ratio of organics were studied and the optimal reaction condition was determined as 450 ℃ ,24 M Pa ,TBP initial concentration of 0.05 mol/L and H2 O2 of one time excess rate .Under such condition ,while the residence time is 10 min ,the decomposition ratio of organics reaches 99.9% .关键词
