摘　　要：为获得影响Fe/AC（活性炭担载金属氧化物）脱硫剂热煤气脱硫效率的工艺条件,对M/AC脱硫剂在输送床反应器上进行了热煤气脱硫试验。研究表明,输送床反应器脱硫可实现连续稳定运行。完成了模拟气氛下热态脱硫试验,模拟气氛为N2＋H2S,试验压力0.1~1.0 MPa。输送床反应器脱硫温度160~180℃,再生反应器温度400~450℃。完成了真实煤气气氛的热煤气脱硫试验研究,试验压力0.5~2.0 MPa,最大处理煤气量120 Nm3/h,最长运行时间约9 h（1.5 MPa,100 Nm3/h）。结果表明,输送床反应器脱硫后,硫化氢含量可低于10 mg/Nm3,COS含量低于30 mg/Nm3,硫化氢脱除率大于99%,羰基硫脱除率可达90%。In order to have the technical conditions affected to the hot gas desulfurization efficiency of the Fe / AC（ activated carbon supported metal oxides sorbent） sorbent,a hot coal gas desulfurization experiment was conducted on the Fe / AC sorbent on the transport bed reactor. The study showed that the desulfurization of transport bed reactor could realize a continuous stable operation. A hot desulfurization experiment under a simulation atmosphere was completed with a simulation atmosphere of N2＋ H2 S and an experiment pressure of 0. 1 ~ 1.0 MPa. The desulfurization temperature of transport bed reactor was 160 ~ 180 ℃ and the temperature of regeneration reaction was 400 ~450 ℃. A study on the hot coal gas desulfurization experiment was completed under the real coal gas atmosphere,the experiment pressure was 0. 5 ~ 2. 0 MPa,the max gas treatment volume was 120 Nm3/ h and the max long operation time was about 9 h（ 1. 5 MPa,100 Nm3/h）. the results showed that after the desulfurization of the transport bed reactor,a hydrogen sulfide content could be lower than 10 mg /Nm3,COS content could be lower than 30 mg/Nm3,a removal rate of the hydrogen sulfide could be higher than 99% and a removal rate of the carbonyl sulfide could reach at 90%.
