摘要
对苏丹Fula-North-3B原油及馏份油中环烷酸的酸值、结构、分子量分布等进行了分析测试和研究. 结果表明:苏丹Fula-North-3B原油中环烷酸的酸值(以KOH计)在10~14 mg/g之间,结构均以一、二、三环为主,在350oC以上,除一、二、三环外,还含有一定量的四、五环的环烷酸. 芳环含量很少, 烯烃双键含量也很少,环烷酸的构成主要是一元酸. 环烷酸的分子量分布情况与馏份的沸程趋势一致. 随着馏份变重,酸值增加、环烷酸的平均分子量增大、分布变宽、碳数范围增加.
The paper analyzes naphthenic acids distribution in fraction oil of the crude oil from a well named Fula-North-3B in an oilfield situated in the north of the Republic of Sudan. Some relative items and properties of the crude oil or its distillates are also determined. This work can provide some basic data, not only for further study on this kind of crude oil, but also for processing and utilizing naphthenic acids.
