| 摘 要： | 采用以烧结金属粉末微孔过滤材料为吸附材料和催化剂基体、CuMn／γ-Al2O3为催化剂的烧结金属催化净化装置，可实现对VOCs废气的有效去除。实验室试验表明：苯、甲苯和二甲苯的催化转化率均随温度的升高而增加。在250℃以上，甲苯和二甲苯的催化转化率高于99％；在280℃以上，苯的催化转化率高于99％。空速为2．0s^-1时催化荆的催化转化率要较空速为3．0s^-1时高。现场试验表明：在300℃左右，VOCs气体经过由烧结金属催化材料刺成的金属过滤器后，苯、甲苯、二甲苯的去除率均高于99％。经金属过滤器处理后，苯、甲苯、二甲苯的排放浓度可低于北京市《大气污染物综合排放标准》DB11／501—2007中的排放限值排放。 |

| Abstract: | To achieve the aim of VOCs removal, the sintered metal materials, the active component CuMn/γ- Al2O3 of catalyst was charged by way of immersion, were tested as adsorption materials. Laboratory experiment results show that the conversion effect of VOCs was increased with temperature. Above 250℃, toluene＇s conversion effect, as well as xylene＇s, was higher than 99%. Above 280℃, benzene＇s conversion effect was higher than 99%. When space velocity is 2. 0 s^-1, benzene＇s conversion effect was higher than the space velocity of 3.0 s^-1. Spot experiment results show that the benzene, toluene and xylene＇s conversion effect at 300℃ could be up to 99%. The VOCs＇s concentration could be removed less than the emission standard of air pollu- tion in Beijing. |
