摘　　要：柴油在储存过程中颜色快速变深,有大量沉渣生成,严重影响其使用性能。本课题选择合适的分离方法对催化裂化柴油中的显色物质用液相色谱与质谱(LC/MS)、气相色谱与质谱(GC/MS)联用技术分析、鉴定柴油主要显色物质的类别、结构,对比加氢精制柴油和催化裂化柴油存在的非烃类物质的结构,提出了可能引起催化裂化柴油变色的主要物质。The color of diesel oil quickly turned depth during storage process,and generated a lot of sediment,which seriously affected its usage performance.With appropriate separation methods,the type and structure of color materials of catalytic cracking diesel oil were analyzed by combined liquid chromatography and mass spectrometry（LC/MS） and gas chromatography and mass spectrometry（GC/MS）.Through the contrast of hydrofining diesel oil and catalytic cracking diesel oil of non-hydrocarbon material structure,the main material may cause the catalytic cracking diesel oil color was proposed.
