以废弃核桃壳作为原料,采用微波加热法制备生物质基多孔活性炭。基于响应面法和数值模拟方法研究活性炭前驱体进行物理活化过程中微波功率、活化时间以及磷酸质量分数对生物质基多孔活性炭吸附性能的影响,对生物质基多孔活性炭制备方案进行优化,并对最优条件下制备的生物质基多孔活性炭进行表征。结果表明,3个因素均对生物质基多孔活性炭的吸附性能有影响,其影响显著性为:微波功率>磷酸质量分数>活化时间。优化的制备条件为:微波加热法对活性炭前驱体进行物理活化过程中的微波功率为746W、活化时间为11.2min以及磷酸质量分数为85.9%。优化生物质基多孔活性炭的碘吸附值为1074.57mg/g,亚甲基蓝吸附值为294.4mL/g,获得率为52.1%。 |

With waste walnut shell as raw material,biomass based porous active carbon was made by microwave oven method.The effects of microwave power,activation time and mass fraction of phosphoric acid on adsorptive property of biomass based porous active carbon in the process of physical activation of active carbon precursor were studied by response surface method and numerical simulation method,the preparation plan of biomass based porous active carbon was optimized,and the optimal biomass based porous active carbon property was characterized.The results show that three factors affect the adsorptive property of biomass based porous active carbon,but the effect of microwave power is obviously more significant than that of mass fraction of phosphoric acid,and the effect of mass fraction of phosphoric acid is more significant than that of activation time.The optimized preparation conditions are:microwave power is 746W,activation time is 11.2min and mass fraction of phosphoric acid is 85.9%in the process of physical activation of activated carbon precursor by microwave heating method.For the optimal biomass based porous active carbon,the adsorption value of iodine is 1074.57mg/g,adsorption value of methylene blue is 294.4mL/g and gain rate is 52.1%. |
