摘要

我国炼油厂废污泥年产量巨大，污泥资源化处理已成为一个亟待克服的难题。为了提高炼油厂罐底油泥热解后可再生气体和轻质油的含量，选择吸波性能和催化性能良好的纳米cuo和纳米-γ-Al2O3，通过实验研究和分析，研究添加剂负荷对热解反应产物特性的影响。结果表明，纳米cuo含量为10%时，油气收率最高。当纳米γ- al2o3加载量为15%时，热解油和热解气收率达到峰值。此外，热解油的轻组分可以得到改善，汽柴油(C4 ~ C12, C13 ~ C18)的比例为75.422%。氢气体积含量在15%负荷时达到最高。

The impact of nano-additives on the properties of sludge microwave pyrolysis products

The annual output of refinery waste sludge is huge in our country, and the resource disposal of sludge has become a difficult problem that needs to be overcome. In order to increase the content of renewable gas and light oil after pyrolysis of oil sludge at the bottom of refinery tank, nano-CuO and nano-γ-Al2O3 with good wave-absorbing property and good catalytic property were selected to study the effect of additive load on the characteristics of pyrolysis reaction products by experimental research and analysis. The results show that the highest oil and gas yields can be obtained when the nano-CuO content is 10%. When nano-γ-Al2O3 was loaded at 15%, the pyrolysis oil and pyrolysis gas yield reached the peak. Moreover, the light component of pyrolysis oil can be improved, and the proportion of gasoline and diesel (C4 ~ C12, C13 ~ C18) is 75.422%. H2 volume content reaches the highest at 15% load.
