摘要
利用9种组分柴油调和为调和柴油,通过柱层析色谱和尿素脱蜡分离正构烷烃,并通过气相色谱分析正构烷烃碳数分布,得出结论:柴油正构烷烃含量和平均碳数都是影响降凝剂在调和柴油中感受性的主要因素。当柴油正构烷烃含量小于20%,且平均碳数为18～19时,柴油降凝剂在柴油中的感受性最好。
The n-alkanes are separated by column chromatography and urea dewax,and the carbon number distribution of n-alkanes are analyzed by gas chromatography with nine-component diesel blended as blended oil.The conclusions show that both the contents of n-alkane and average carbon number are the most important influential factors to blend diesel.When the contents of n-alkane below 20%,average carbon number is between 18 and 19,the response of depressant in diesel is the best.
