【摘要】 以NH3为还原性气体对负载型CuO/复合载体脱硫剂进行了再生研究。在固定床反应器中对再生脱硫剂的脱硫性能进行了考察,以穿透时间为指标,结合BET和FT-IR表征手段,考察了温度、时间对脱硫剂再生性能的影响。实验结果表明:最佳再生温度和时间分别为300℃、100min;脱硫剂CuO/活性炭+凹土吸附试具有丰富的孔结构;脱硫剂重复使用4次,仍然保持了较好的脱硫性能,其穿透硫容高于30mg/g。更多还原

【Abstract】 The regeneration of absorbent CuO supported on the complex carrier of attapulgite and activated carbon was carried out using NH 3 for the flue gas desulfurization. With the breakthrough time as an index,the desulfurization performance of regenerated sorbents under different conditions was tested in a fixed- bed reactor, combined with characterizations of BET and FT- IR. The experimental results showed that the optimum regeneration time and regeneration temperature was 300℃ and 100 min,respectively. Due to the porous structure of CuO / complex carrier,the breakthrough sulfur capacity of the sorbent regenerated for 3 times was still over 30 mg / g,which proved its good future in industrial application.更多还原
