Abstract

The effect of an inhibitory composition based on an amphiphilic polymer of polyacrylate and stearic acid on the composition of paraffinic hydrocarbons in asphalt–resin–paraffin deposits (ARPDs) of high-paraffin oil was studied. It was shown that the molecular weight distributions of paraffinic hydrocarbons in the ARPDs were different upon the addition of the amphiphilic polymer and the composition to oil. The action of the polymer led to a decrease in the total concentration of C16–C21 hydrocarbons and an increase in the fraction of high-molecular-weight C22–C34 hydrocarbons. On the contrary, the use of stearic acid as a surfactant in the composition decreased the amount of high-molecular-weight paraffin hydrocarbons.

抑制性成分对油类沉积物中石蜡碳氢化合物成分的影响
摘要 研究了基于聚丙烯酸酯和硬脂酸两亲性聚合物的抑制组合物对高沥青质油的沥青-树脂-石蜡沉积物(ARPDs)中石蜡烃组成的影响。结果表明,在油中添加两亲聚合物和组合物后,ARPDs 中石蜡烃的分子量分布有所不同。在聚合物的作用下,C16-C21 碳氢化合物的总浓度降低,而高分子量 C22-C34 碳氢化合物的比例增加。相反,在组合物中使用硬脂酸作为表面活性剂会减少高分子量石蜡烃的含量。

期刊介绍: The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
