摘要/Abstract

摘要： 针对柴油储存过程中质量衰变问题，利用典型柴油样品，开展烃化合物对中国成品柴油储存安定性影响规律研究。烃组成分析测定结果表明，柴油中总芳烃和链烷烃之间存在很强的相关性（相关系数为0.90）。综合采用相关分析、逐步线性回归等方法，建立了安定性指标与烃组成的关联模型，拟合验证表明模型可靠，可以直接用于柴油储存安定性预测；研究确定了柴油储存安定性的主要影响物质，按照对储存安定性指标影响的严重程度将烃类物质分为三个等级，其中苊烯和三环芳烃对柴油质量衰变影响最大，链烷烃对十六烷值和热值影响最大。

Abstract: Diesel is known to deteriorate in quality during storage. To examine this issue, the effects of various hydrocarbon compounds on the stability of processed diesel fuels from China were investigated using typical samples of diesel. The results of the hydrocarbon composition analyses indicated that the total aromatics and paraffin contents of diesel are strongly correlated with each other (with a correlation coefficient of 0.90). Through the combined use of correlation analysis and stepwise linear regression, a correlation model was constructed for stability indicators with respect to hydrocarbon composition, and validated through fitting experiments. It was shown that this model can be used to accurately predict the stability of diesel storage. Hydrocarbon compounds with the largest impact on diesel storage stability were determined and were divided into three grades according to their influence on storage stability. It was found that acenaphthylene and tricyclic aromatic hydrocarbons have the largest influence on the deterioration of diesel quality, whereas paraffin has the greatest effect on the cetane number and calorific value of the diesel.

Key words: diesel, storage stability, hydrocarbon composition, regression analysis, acenaphthylene, tricyclic aromatic hydrocarbons
