摘要： 在流化床上制备活性焦(AC)并考察了煤种及活化条件(活化温度、活化时间及活化介质中水蒸汽浓度)对其脱硫性能的影响. 结果表明彬县煤是制备脱硫用活性焦的较佳煤种，在活化温度为800~900℃、活化时间为20~60 min、水蒸汽浓度为30%~80%(j)的范围内，制得的活性焦碘值为573~805 mg/g、苯甲酸吸附量为0.24~0.26 mmol/g、硫容(SO2)为174~275 mg/g.

Abstract: The effects of coal type and activation conditions on the desulfurization capability of activated coke in a fluidized bed were studied. The results show that compared with Datong coal, Binxian coal is a better raw material for activated coke used in flue gas desulfurization. The iodine value, benzoic acid sorption and sulfur capacity of the activated coke prepared from Binxian coal increase with activation temperature, activation time and concentration of water vapor in the activation agent. The activated coke with the sulfur capacity of 174~275 mg/g can be prepared from Binxian coal under the following activation conditions: activation temperature of 800~900oC, activation time of 20~60 min, and concentration of water vapor of 30%~80%(j).

Key words: desulfurization, sulfur dioxide, flue gas, activated coke, activation
