The Catalytic Oxidation of Benzene by Hopcalite under Microwave Irradiation

摘要

In order to explore an efficient and rapid method for treating typical volatile organic compounds(VOCs), benzene, as a representative of VOCs, was catalytically oxidized by hopcalite under microwave irradiation. The decontamination performance under different conditions was studied, and the influences of some factors on the benzene conversion ratio were tested, such as microwave irradiation power, initial benzene concentration, catalyst amount and gas humidity. Results showed that benzene conversion ratio could reach 99.2% under the condition that microwave power, initial benzene concentration, gas flow and catalyst bed height were 70W, 1917mg/m~3, 1.0L/min, and 3.86cm separately. It is concluded that microwave irradiation can promote the catalytic oxidation of benzene and it has higher energy efficiency than traditional heating.
