Abstract

The article investigates the influence of the hydrocarbon composition of various samples of straight-run diesel fuels on the depressant additives efficiency. During the study the characteristics and composition of straight-run diesel fuels of various origins were determined; blends of straight-run diesel fuel samples with depressant additives were prepared, their low-temperature properties were determined. It was found that the effectiveness of the depressant additives in relation to the pour point of diesel fuel increases with an increase in the content of paraffins in the fuel composition, a decrease in the content of aromatic hydrocarbons, an increase in the average number of aromatic rings in the molecule. The effectiveness of the depressant additives in relation to the cold filter plugging point of diesel fuel increases with a decrease in the content of paraffins in the diesel fuel, and an increase in the initial boiling point of fuel. The regularities of the influence of the composition of straight-run diesel fuels on the effectiveness of the depressant additives revealed in the study will make it possible to choose the most effective additives and select their optimal concentrations.

直馏柴油中减压添加剂与烃类相互作用的研究

本文研究了各种直馏柴油样品的碳氢化合物组成对抑制剂添加剂效率的影响。在研究过程中，确定了不同产地直馏柴油的特性和组成;制备了添加抑制剂的直馏柴油样品的共混物，并对其低温性能进行了测定。研究发现，随着燃料成分中石蜡含量的增加、芳香烃含量的降低和分子中平均芳环数的增加，抑制剂添加剂对柴油倾点的影响也随之增加。随着柴油中石蜡含量的降低和燃料初沸点的升高，抑制剂添加剂对柴油冷滤芯堵塞点的影响增大。研究揭示了直馏柴油成分对抑制剂添加剂效果影响的规律，为选择最有效的添加剂及其最佳浓度提供了可能。
