摘要: 为解决废旧轮胎热解油颜色过深和存在异味而无法直接利用问题,文章采用活性炭对热解油吸附脱色工艺,将液相中含有的杂质、色素、异味等舍弃物吸附于活性炭表面上,以达到精致的目的。试验表明:热解油活性炭吸附脱色技术的最佳工艺条件为炭粒度550~1 700μm、脱色温度为室温、吸附时间为300 min、振荡频率为150r/min。并证明了平均孔径、中孔孔容积和中孔比表面积为26.4Å、0.307mL/g和280m²/g的烟煤基活性炭对热解油具有很好的脱色能力。

Abstract: To solve the problems that pyrolysis oil from waste tires treatment is too dark with peculiar smell and cannot be used directly, in this paper, activated carbon is adopted for adsorption of pyrolysis oil. Impurities, pigment, peculiar smell and other discarded matter contained in the liquid phase are adsorbed on the activated carbon surface so as to achieve the refining purpose. The experiment results show that the optimal conditions of adsorption and decolorization of pyrolysis oil with activated carbon are as follows:carbon size is 1 700 μm~550 μm, decolorization temperature is at room temperature, adsorption time is 300 min, and oscillation frequency is 150 r/min. From the experiments, it is also proved that bituminous coal based activated carbon, with average pore diameter of 26.4 Å, mesoporous pore volume of 0.307mL/g and mesoporous specific surface area of 280 m²/g, has good capacity for decolorization of the pyrolysis oil.
