| 摘要: |
| 以石油焦和含油污泥为原料,在活化剂的作用下共同热解制备多孔活性炭材料。将得到的多孔碳进行碘吸附值、苯吸附值、BET等测定,确定多孔碳的比表面积及孔结构。研究硝酸预处理石油焦对多孔碳性能的影响以及微波功率和微波辐照时间对多孔碳的影响。结果表明:经硝酸氧化处理所得的活性炭吸附性能明显提高;微波功率越高对物料的活化作用越好,经微波活化的活性炭吸附性能越好;在微波功率800 W条件下,比表面积最大为1396.91 m2/g;微波加热时间约30 min可获得明显的催化效果。 |

| Abstract: |
| The petroleum coke and oily sludge were used as precursors to prepare porous activated carbon (AC) with activator through pyrolysis. Iodine adsorption value, benzene adsorption value and Brunauer-Emmett-Teller (BET) test were conducted to determine the structural characteristics of the AC samples. And the influence of pretreated petroleum coke by Nitric acid and the microwave power, as well microwave irradiation time on the porous carbon of, were investigated. It is found that the adsorption performance of the activated carbon after nitric acid oxidation treatment is improved significantly. The higher microwave power favors the adsorptive property. The BET specific surface reaches 1396.91 m2/g at the microwave power of 800 W. A significant catalytic effect can be obtained after microwave heating time of around 30 min. |
