摘要：

为了研究不同来源吸附剂对烟气中二恶英的吸附效果,选取颗粒活性炭和废轮胎热解焦炭2种吸附剂.实验在管式反应炉中进行,通过设置不同的吸附床层温度和空速条件,对2种吸附剂脱除二恶英的吸附效率进行比较.研究发现：活性炭对烟气二恶英毒性当量的吸附效率较高,当床层温度＜200 ℃时可以达到大于98％的吸附效率；废轮胎热解焦炭的吸附效率稍低,对烟气二恶英毒性当量的吸附效率＞65%,最高为86%.
Abstract:

Two kinds of adsorbents like granulated activated carbon and coke from pyrolysis of scrap tires were applied in order to test their adsorption efficiency for dioxins in flue gas. The experiment was conducted in a quartz tube reactor, and the dioxin adsorption efficiency was tested for two sorbents at different adsorbent bed temperatures and space velocities. Results show that with respect to the activated carbon, the toxicity equivalence quantity (TEQ) adsorption efficiency is much higher than the concentration adsorption efficiency. When the temperature of the fixed adsorbent bed is lower than 200 ℃, the adsorption efficiency is higher than 98%. The dioxin adsorption efficiency for pyrolyzed coke is a little lower than activated carbon, however, the TEQ adsorption efficiency is still higher than 65%, and the maximum is 86%.
