为研究非石油基组分油用于渣油掺稀降黏的机理和黏温模型,测定了页岩油、水上油和煤柴油等3种非石油基组分油用于辽河减压渣油掺稀降黏的黏温数据。实验结果表明,3种稀油对渣油降黏效果显著。分析认为:沥青质基本片层结构之间的缔合作用力是影响渣油掺稀降黏效果的重要因素。将张克武导出的液体黏度理论方程拓展应用于渣油掺稀混合油的黏温关系描述。基于实验和分析,提出渣油掺稀降黏包括沥青质稀释和解缔两种机理,并建立了渣油掺稀降黏模型。该模型计算值与实验值吻合较好。模型参数反映了混合油的构成和稀油对渣油沥青质缔合作用的影响,具有一定的物理意义。
In order to study the mechanism and viscosity-temperature model of non-petroleum-based component oil for dilute viscosity reduction of residue, three kinds of non-petroleum-based component oils such as shale oil, water oil and coal-diesel were determined for Liaohe vacuum residue Sparse dilute viscosity viscosity data. The experimental results show that three kinds of thin oil on the viscosity reduction effect of residue significantly. The analysis shows that: the association between the basic lamellar structure of asphaltene is an important factor that affects the effect of slag dilution and viscosity reduction. Zhang Kewu derived liquid viscosity theory equation extended to the viscosity of residue mixed with oil viscosity relationship description. Based on the experiment and analysis, two mechanisms, dilution-desorption and desorption of residue, including asphaltene, were proposed, and a model of dilution-viscosity reduction of residue was established. The calculated value of the model is in good agreement with the experimental data. The model parameters reflect the composition of mixed oil and the effect of dilute oil on the association of residual oil asphaltene, which has certain physical meaning.
