摘　　要：研究了利用烟秆制备廉价活性炭的可行性。通过系统的工艺条件考察,寻求合理优化的工艺路线和条件。采用氮气保护,在钢甑炭化炉中进行炭化,在管式不锈钢反应器中进行活化。较优的工艺条件为:炭化温度300℃,炭化反应时间0.5h,活化温度750℃,活化反应时间0.5h,水/炭比2/1,所得活性炭产品的碘吸附值为849.6(mg/g);比表面积为630.3(m2/g)。The feasibility of low-cost activated carbon by using tobacco stalk preparation is discussed. Based on systematic inspection process, we search for optimized process route and conditions. Nitrogen is used as protection in steel carbonized rice pot furnace for earbon and in stainless steel pipe reactor for activation. The better condifons are as follows： carbonization temperature of 300 ℃, reaction time, charting 0.5 h, activation temperature 750 ℃, activation reaction time 0.5 h, water/C2/1, the iodine absorption value of activated carbon products 849.6 （mg/g ） ; surface area is 630.3 （m^2/g）.
