摘　　要：2003年济钢焦化厂引进焦炉煤气精脱萘工艺,利用柴油循环脱萘。鉴于精脱萘工艺柴油成分复杂,混合物性质极为相近的特点,开发了采用气相色谱法测定循环柴油中萘含量的分析方法,并确定了其检测条件。该法操作简便、快速,数据准确,其检测结果为精脱萘工艺生产提供了及时、准确的指导数据。As the composition of diesel oil mixtures are complicated and their properties are similar to each other, a method of using gas chromatography to determine the naphthalene content in the circulative diesel oil formed in the purifying process was developed and the detection conditions were confirmed. This method is simple, rapid and accurate. The results can be used to guide the operation of the purifying process.
