【摘要】 本文采用前人研究制备的高活性吸收剂,在固定床试验中研究了影响三氯苯去除效率的若干因素,并进行了理论推导和验证。在最佳试验条件下,前12min内的去除效率保持在60%以上,前10min内最大平均去除效率为81.71%,每克吸收剂的最大处理能力约为0.111mg。采用气相色谱/质谱(GC/MS)对反应后吸收剂中中间产物进行了监测,通过初步反应机理研究,证实三氯苯在高活性吸收剂的作用下发生了化学反应,主要的中间产物是2,6-重(1,1-二甲基)-4-甲基-苯酚,最终产物为CO2和H2O,未检测到二恶英类物质,表明高活性吸收剂表面的碱性物质吸收了三氯苯降解产生的氯元素,阻断由其生成二恶英类物质的路径。更多还原

【Abstract】 The removal and influencing factors of trichlorobenzene by highly reactive absorbent were studied in fixed bed, which any person processed and researched, the theory of this was also deduced and verified. In the optimum conditions of trichlorobenzene removal, the removal efficiency is up 60% in the first 10 min, the max removal efficiency 81.71% in first 10 min, and the max removal weigh is 0.111mg by per absorbent. Residual major intermediate products in the reacted absorbent ware detected, preliminary reaction mechanism suggested that some chemical reaction had happened. 2,6-Bis-[1,1-Dimethylethyl]-4-methyl-Phenol is the major intermediate product in the reaction, CO2 and H2O are eventual products; PCDD/Fs are not detected out by GC/MS, this maybe the formation routs ware blocked off by the highly reactive absorbent which absorbing Cl decomposed from trichlorobenzene.更多还原
