Oil storage tanks and their pipelines are mostly constructed under the ground. If the leaches are occurred, the soil pollution and the contamination of groundwater quality will influenced seriously. The soil of oil polluted sites is usually containing the huge amounts of volatile organic compounds (VOCs) and other organics. These VOCs is uncomfortable on physical body when they spread into atmosphere not only to cause the harm of human health but also to react into photochemical smog. Besides, the VOCs are probably reacting with nitrogen oxides into the problems of high concentrations of ozone. In this study, we used a regenerative catalytic oxidizer (RCO) to deal with VOCs in soil of the oil polluted sites. The RCO system was packed with self-made catalyst of 20 wt%CuMn/£^-Al2O3. Experimental results revealed 90¡Ó5% of the influent VOCs (C0=450-10,000 ppm) was thermally destruction with no catalyst in beds operated with a valve shifting time (ts) of 2 min, superficial gas velocities (Ug) of 0.37 m/s (evaluated at an influent air temperature of around 30¢J) and present maximum destruction temperature (TS) of 800-900¢J. With the catalyst packings and operation conditions of Ug=0.37 m/s and C0=450~10,000 ppm, the destruction efficiency of 93.35 and 96.5% were observed, respectively in average at TS of 600 and 650¢J. When Ug=1.11 m/s and C0=450-10,000 ppm, the destruction efficiency of 87.51 and 93.75% were observed, respectively in average at TS of 600 and 650¢J. The destruction efficiency of RCO is high at higher influent concentration of VOCs and low gas velocities at TS=600-650¢J.
