SiC를 이용한 BTEX 제거 연구

초록

Recent industrial developments have increased the use of Volatile Organic Compounds (VOCs). Odors (e.g., arehydrogen sulfide, mercaptan- type, amine- type and other irritating pungent gaseous or volatile substances)., whichare disgusting and disgusting to humans. Currently, regenerative thermal oxidation (RTO), regenerative catalyticoxidation (RCO), Carbon Adsorption Tower, etc. are used for their control to remove VOCs. In this experiment,we report the use of silicon carbide (SiC) for the control of four common VOCs called BTEX (i.e., benzene,toluene, ethyl benzene and, xylene (BTEX))., which is a representative material of VOCs, was removed by usingsilicon carbide (SiC). The heating SiC was heated be tween 400oC and 700oC in a microwave,. As a result, weobserved the removal efficiency of BTEX from 10 ppm to 50 ppm was. At 400oC and 500oC, 0.6~60.3% and11~64.7% the removal efficiency were achieved, with exponential increase at the temperature from 500oC. At600oC, it showed more than 69.0~100% removal efficiency of most BTEX materials. Finally, At 700oC, it wasconfirmed that all BTEX materials were completely removed.
