摘　　要：采用气相色谱配硫化学发光检测器(SCD)结合高温模拟蒸馏ASTM D7169-05方法对巴陵石化催化裂化油浆中含硫化合物进行了分析鉴定,结果表明:油浆的馏程在253℃到690℃左右范围内,硫化物类型主要是二苯并噻吩类和萘并噻吩类化合物;定量分析结果表明,萘并噻吩类化合物占油浆中总硫化物含量的70%以上。The catalytic cracking slurry was analyzed by gas chromatography with sulfur chemiluminescence detection （GC-SCD） and SimDis ASTM D7169-05 method. The results show that distillation range of the slurry is from 253 ℃to 690℃,and main sulfide types are dibenzothiophenes and naphthothiophenes. Quantitative analysis results show that naphthothiophene compounds account for more than 70% of the total sulfur content in the slurry.
