摘要

研究了温度和用量对麻疯树籽油作为沥青质稳定剂效果的影响。使用两种原油样品(轻质和中质)。取未加热样品(25℃)，在100、150和170℃加热24 h，在10 ml样品中分别以2、4、6和8 μL的剂量施用麻瓜油。沥青质不稳定性指数(AII)为使沥青质絮凝的正庚烷用量与分散絮凝体的二甲苯用量之比。试验设计为田口因子，一个响应变量(AII)和两个实验因子(施加剂量和加热温度)有响应面。对于轻质原油，最佳反应条件为8 μL，温度为127℃，反应效率为85.3%;对于中等原油，最佳反应条件为2 μL，温度为25℃，反应效率为94.3%。考察了麻籽油的提取效率，以及麻籽油的种类对提取结果的影响。

Analysis of factors affecting the efficiency of Jatropha curcas oil as an asphaltene stabiliser

The effect of temperature and applied dose on the efficiency of Jatropha curcas seed oil as an asphaltene stabiliser was studied. Two crude oil samples (light and medium) were used. J. curcas oil was subjected to heating at 100, 150 and 170 °C for 24 h with an unheated sample (25 °C) and applied at doses of 2, 4, 6, and 8 μL in 10 ml of sample. The asphaltene instability index (AII) was determined as the ratio between the amount in ml of n-heptane to flocculate the asphaltenes and the amount in ml of xylene to disperse the flocs. The experimental design was Taguchi factorial with a response surface for one response variable (AII) and two experimental factors (the applied dose and heating temperature). For light crude oil, the optimum conditions were 8 μL and T = 127 °C with an 85.3 % efficiency and for medium crude oil, 2 μL and T = 25 °C with a 94.3 % efficiency. The efficiency of J. curcas oil and the influence of the type of crude oil on the results obtained were demonstrated.

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
