摘　　要：采用活性炭液相静态吸附法对煤基乙二醇产品进行精制,研究活性炭改性方法以及原料来源对煤基乙二醇紫外透光率和产品色度的影响,结果表明木质炭和椰壳炭组合改性吸附后,煤基乙二醇产品品质明显提升,效果优于催化加氢。在此基础上研究放置时间和测试过程中参比水的影响。The activated carbon static adsorption method was employed to refine the coal-based ethylene glycol product, and the effects of the modification methods of active carbons and the sources of raw materials for preparing activated carbons on the UV transmittance and the color of the ethylene glycol product were investigated. The results showed that the quality of coal-based ethylene glycol product was significantly improved after adsorption treatment using the mixed activated carbon of wood charcoal and coconut shell charcoal, and the refining effect of activated carbon was better than that of catalytic hydrogenation. The effects of the sample storage time and the reference waters for testing were also investigated.
