Radiation-thermal purification of wastewater from oil pollution

Abstract

The results of study oxygen's influence on the radiation-thermal decomposition of n-heptane admixtures in water medium are adduced. The main parameters of radiolysis were changed within the limits: temperature 20-400°C, absorbed dose-0÷16.0 kGy at dose rate 3.2 kGy/h. As a product of decomposition are observed H2, CO, CH4, C 2H4, C2H6, C3H 8, C3H6, C4H8, hydrocarbons C5-C6. The changes of n-heptane concentration in the reactor also are established. The increasing of n-heptane decomposition rate and decreasing of gas formation rate in presence of O2 are observed. As a result of summarizing of experimental data, the kinetic model of processes has been proposed. © 2007 Springer.
