Abstract
p-Xylene removal is carried out using nonthermal plasma combined with adsorbent. The zeolite molecular sieve pellets are used as adsorbent. After p-Xylene is adsorbed by adsorbent for 130min, regeneration of adsorbent is performed using nonthermal plasma for 4min. However, the regeneration efficiency is 4.5%. Also ozone concentration in exhaust gas is 150〜250ppm. In order to improve regeneration efficiency and control ozone exhaust, regeneration of adsorbent is carried out using nonthermal plasma with circulating exhaust gas. As a result, the regeneration efficiency of 70% is achieved by circulating for 60min and the amount of ozone exhaust with circulating exhaust is less than 1/7 of that without circulating exhaust.
