摘　　要：钢铁行业对钢材冷却时会产生大量含油污泥,对环境造成了严重污染。对含油污泥的热解过程进行了实验和仿真模拟研究,并对实验中分离出的热解油进行组分分析。轻质油中脂肪族化合物、杂环化合物和芳香族化合物分别占97.8%、1.85%和0.35%。重质油中脂肪族化合物和杂环化合物分别占93.27%和6.73%。另外通过Aspen Plus建立模型,并根据模型数据对热解过程的收支平衡进行分析。研究表明热解产物携带能量从大到小依次为热解油、残渣、热解气和水。含油污泥产出的挥发分质量占比为69.4%,能够有效利用的化学能较多。The steel industry produces a lot of oily sludge when cooling steel,which causes serious pollution to the environment.Experimental investigation and simulated analysis were conducted on the pyrolysis process of oil sludge,and a compositional analysis was performed on the pyrolysis oil separated during the experiment.Within the light oil fraction,aliphatic compounds,heterocyclic compounds and aromatic compounds account for 97.8%,1.85%,and 0.35%,respectively.As for the heavy oil fraction,aliphatic compounds and heterocyclic compounds make up 93.27%and 6.73%,respectively.Additionally,the model was established by Aspen Plus,and the mass and energy balance was analyzed according to the model data.The results showed that the energy carried by pyrolysis products is pyrolysis oil,residue,pyrolysis gas and water in descending order.The volatile matter produced by oily sludge accounts for 69.4%,which indicates that there are more chemical energy that can be effectively utilized.
