摘　　要：为加深学生对碳排放、碳中和在化学工程与能源利用领域的理解,设计了一个完全基于生物质资源的活性炭制备与吸附性能探究综合性实验。以生物质热解液替代常规化学品(如磷酸、氢氧化钾或氯化锌等)作为活化剂,以玉米芯或核桃壳为原料制备活性炭,并对其吸附性能进行研究。结果表明:浸渍时间对活性炭吸附量影响不大,浸渍比对玉米芯基活性炭吸附量影响较大。玉米芯基活性炭和核桃壳基活性炭分别在浸渍比1∶12和1∶8时吸附量最大,对应的亚甲基蓝吸附量分别达8.67 mg/g和14.53 mg/g。To enhance students’ understanding of carbon peak and carbon neutrality in chemical engineering and energy utilization, a comprehensive experiment on the preparation and adsorption performance of activated carbon based entirely on biomass resources is designed. Using biomass pyrolysis liquid instead of phosphoric acid, KOH or zinc chloride as the activator, using corn cobs or walnut shells as raw materials to prepare activated carbon, and its adsorption performance has been investigated. The results show that the dipping time has little effect on the adsorption capacity of activated carbon, and the dipping ratio has a greater impact on the adsorption capacity of corncob-based activated carbon. The adsorption capacity of corncob-based activated carbon and walnut shell-based activated carbon are the highest when the impregnation ratio is 1∶12 and 1∶8, respectively, and the adsorption capacity of methylene blue is 8.67 mg/g and 14.53 mg/g, respectively.
