Summary: | Fly ash, industry lime and an additive, Ca(ClO₂ )₂ (C) were used to prepare the ‘oxygen‐enriched’ highly active absorbent (HAA). The influencing factors for removal of 1,2,4‐trichlorobenzene (TCB) using this absorbent such as reaction temperature, simulating gas flow rate, oxygen content, etc. were studied in a self‐designed reactor. The optimum experimental conditions of removing 1,2,4‐TCB are that the content of an oxidizing additive in the absorbent is 3% (wt), simulating gas flow rate is 100 mL/min, reaction temperature is 250°C, and the content of oxygen in simulating gas is 6%. The maximum removal efficiency is 81.71% in 10 mins. The absorption capacity of the absorbent is 0.000111 g/g. The reaction products were determined by gas chromatograph/mass spectrometer (GC/MS), 2,6‐Bis‐[1,1‐Dimethylethyl]‐4‐methyl‐Phenol is considered to be the major intermediate product. The reaction route was revealed. |
