Moreover,the paper puts forward the opinion that the incompatibility between asphaltene components and light hydrocarbons can be described with larger interaction coefficients.

此外，文章提出了大的交互作用系数可以描述沥青与原油中轻烃不相溶性的观点。

The interfacial tension and interfacial shear viscosity of polymer solution/asphaltene model oil were measured respectively by Wilhelmy method and biconical bob method.

用挂片法和双锥摆法测定了聚合物溶液/沥青质模拟油体系的界面张力和界面剪切粘度，并对聚合物浓度对其的影响进行了分析。

The comparison of IR spectrum and X-ray diffraction and waxy crystal size for paraffin, gum ,and asphaltene before and after treatment was made.

用降凝降粘剂EVA+AA处理高蜡原油，并对原油处理前后的石蜡、胶质、沥青质进行红外特征吸收峰、X射线衍射峰以及蜡晶尺寸变化研究。

The results indicated that the diffusibility of AR and dissolvability of resin and asphaltene in AR were enhanced by adding HCO and LCO additives,the HDM performance of AR was improved,among which the improvement of hydrodenickel revealed a distinct advantage over hydrodevanadium;Afte...

结果表明，HCO和LCO添加剂的加入，可改善渣油在反应过程中的扩散性能，促进渣油中沥青质的溶解，从而提高渣油的HDM性能，其对加氢脱镍性能的提高更优于加氢脱钒。

This technique reveals the dispersed polymer-rich phase as bright, while the continuous asphaltene-rich phase remains dark.

而饱含连续的asphaltene的阶段依然是黑暗，这个技术显露了将被分散的饱含聚合物的阶段作为明亮的。

Finally, two short-path distillation processes and one falling film evaporator are applied in the regeneration of waste lubricating oil. In the test, the diesel oil, gasoline and lubricating oil are distilled respectively, while the gelatinoid materials, asphaltene and carbon residue remain in the draft. The regenerative lubricating oil accords with the standards of base oil. And the recovery efficiency is up to 75 percent. The technology used in the test doesnt comprise processes like pickling and alkali neutralization, which would cause secondary pollution like acid draff and sulfur dioxide and so on. As a result of this, our technology is friendly to the environment.

最后，利用一级薄膜蒸发和两级短程蒸馏工艺对废润滑油进行了再生回收工业应用试验，将柴油、汽油等轻油以及润滑油馏分分别蒸馏出来，而大部分胶质、沥青质、碳垢存在于残渣中，试验得到的再生润滑油符合基础油的标准，回收率达到75％，达到废润滑油再生的目的；同时再生过程中没有酸洗、碱中和等工序，不产生酸渣、二氧化硫等二次污染，是一种清洁环保的废润滑油再生工艺。

Remarkable changes are ubiquitous for NSO fractions and asphaltene. The yields of fatty acids from copper-treated EOM, in particular palmitic acid and stearic acid, do not decrease for the interaction of copper with organic acids but increase markedly.
