The parametric tests were conducted at the reaction temperature range of 200~500 ℃, benzene concentration of 400~650 ppm, gas flow rate of 50~100 cc/min, and space velocity range of 7,500~22,500 hr -1 . The property analyses by using the BET, SEM, TGA and the conversion of catalytic oxidation of benzene were examined. The experimental results showed that the conversion was increased with decreasing benzene concentration, gas flow rate and space velocity. Benzene oxidation reaction over Cu/γ-Al2O3 catalyst could be expressed as the first order homogeneous reaction of which the activation energy was 17.2 kcal/mol and frequency factor was 1.33 × 10 6 sec -1 .
