摘　　要：为制备高强度脱硫用活性焦，以太西无烟煤为主要原料，研究了原料煤配方、活化时间和水蒸汽流速等对制备活性焦产品性能的影响。结果表明：以无烟煤精煤为原料．活化温度为850℃，活化时间为15min，水蒸汽流速为6．2mL／min时，活性焦产品碘值最大为356mg／g，强度最低为99．18％．符合理想活性焦产品碘值300～400mg／g，强度大于99％的要求。太西无烟煤原煤与其他某煤种质量比为75：25，活化温度为850℃，活化时间为15min，水蒸汽流速为4mL／min时，制备活性焦产品碘值为320mg／g，强度为99．2％，活性焦的吸附性能和耐磨性能均最好。To prepare high intensity and desulfurized active coke,using Taixi anthracite as the main raw material,investigate the influence of formulation of raw material coal, activation time and steam velocity on the preparation.The results show that, using pure clean anthracite as raw material ,when the activation temperature is 850℃, the activation time is 15 minutes, steam flow rate is 6.2 mL/min ,the maximum iodine value of activated coke sample is 356 mg/g, the minimum intensity is 99.18 percent.The desired iodine value ranges from 300 mg/g to 400 mg/g,the intensity should be greater than 99 percent.So it is good preparation technology parameters of activated coke.When the mass ratio of Taixi anthracite and other type of coal is 75 ： 25, activation temperature is 850 ℃, the activation time is 15 minutes, steam flow rate is 4 mL/min, the iodine value of activated coke sample is 320 mg/g,the intensity is 99.2 percent, the adsorption properties of activated coke and wear-resisting performance are the best.
