| 摘 要： | 以木屑炭为原料,水蒸气为活化剂,采用流态化工艺制备活性炭,研究了活化温度、载气流量、水蒸气流量、进料速度等因素对活性炭性能的影响。通过正交试验,确定了最佳工艺条件为活化温度870℃、载气流量250 m3/h、水蒸气流量150 m3/h、进料速度54 kg/h。在最佳工艺条件下,产品碘吸附值为1 162 mg/g,得率为31.62%。方差分析表明:对活性炭产率来说,只有活化温度的影响达到显著水平,其它因素的影响均不显著;对活性炭碘吸附值来说,活化温度、水蒸气流量、载气流量3因素的影响均达到显著水平。

| Abstract: | Activated carbon was prepared by fluidization progress from sawdust charcoal using water vapor as activator.The factors effects on properties of activated carbon such as activation temperature,carrier flow,water vapor flow,feed rate were studied.The optimum conditions obtained by the orthogonal experiments are as follows: activation temperature 870 ℃,carrier flow 250 m3/h,water vapor flow 150 m3/h,feed rate 54 kg/h.Under these conditions,the product yield is up to 31.62 % with the iodine adsorption up to 1 162 mg/g.The analysis of variance showed that the activation temperature is the only significant impact factor for product yield.The impact factors such as activation temperature,water vapor flow and carrier flow are significant for the iodine adsorption. |
