摘要
采用气相色谱 -原子发射光谱联用 (GC -AED)技术 ,研究了柴油馏分加氢前后各种硫化物的变化。在加氢脱硫过程中 ,二苯并噻吩类化合物中的硫最难脱除 ,催化剂的类型及各操作参数的选择应以柴油中二苯并噻吩类化合物含量来确定。研究了某加氢柴油进行微生物脱硫处理后各种硫化物的变化 ,并研究了硫含量不同的柴油馏分进行微生物脱硫处理后各种硫化物的分布。可选取在加氢脱硫过程中将柴油中的硫含量降到多大时 。
The distribution of various each sulfurcompounds in diesel oil before and after hydrosulfurization by gas chromatography- atomic emission detector (GC - AED) was studied. Alkyl - dibenzothiophenes in diesel oil are most difficult to be removed. Optimization of catalyst andoperation condition (temperature, pressure, ratios of hydro gen and oil) is depended on the content of alkyl - dibenzoth iophene in diesel oil. The contents of each sulfur compound in diesel oil were determined after these diesel oils weredesulfurized by bacteria. The best project can be obtained between hydrodesulfurization and bacteriadesulfurization by GC - AED.
