Characteristics of VOC(benzene) Treatment Using Catalyst and Adsorption Technology

Characteristics of VOC(benzene) treatment were investigated using a fixed bed reactor system over copper base catalyst and photocatalyst/adsorbent blending material. The copper base catalysts were made by using copper nitrate reagent and various support materials such as γ-Al₂O₃, TiO₂. The parametric tests were conducted at the reaction temperature range of 200～400℃, benzene concentration of1,000～2,000 ppm, and space velocity range of 5,000～10,000 hr^-1. The property analyses such as BET, SEM and the removal efficiency(conversion) of VOC were examined. The experimental results showed that the VOC removal efficiency of hybrid method was higher than that of single method. It was also found that the comprehensive feasibility study of hybrid method would need with considering various factors including additional expenses.
