【摘要】 用生物质裂解残炭制备活性炭,应用正交实验法对诸多影响因子进行考察,在优化工艺条件(活化温度770-780℃、活化时间4小时、水/原料=200、氮气/水=0.5)下,可以得到碘值691.94 mg.g-1,亚甲蓝值280.93 mg.g-1左右的活性炭产品。
【Abstract】 Activated carbon is prepared by residual carbon obtained by fast pyrolysis of biomass. The various impacted factors are researched by orthogonal experimental method. Under the preferential conditions (activation temperature is about 770-780, activation time is 4hrs, value of the mass of water/sample is 200, value of the mol of nitrogen/water is 0.5), the activated carbon can be obtained which iodin adsorption value and methylene blue adsorption value is 691.94 mg · g-1 and 280.93 mg·g-1 resprctively.
【Key words】 Biomass； residue carbon of biomass pyrolysis； activation； activated carbon； orthogonal experiment； iodin adsorption value； methylene blue adsorption value；
