摘要
采用馏分切割,模拟脱臭的试验方法,通过研究脱臭前后重油催化裂化汽油中硫醇硫的含量分布及存在形态,得出制约脱臭效果的关键馏分为第6馏分,即温度范围为180℃～终馏点的馏分。分析结果发现,影响脱臭效果的关键组分是C_7、C_8硫醇的同分异构体。
By using the testing methods of distillate cutting and simulated sweetening, the con-tent, distribution and forms of mercaptan contained in gasoline before and after sweetening were stud-ied. The conclusion was drawn that the key fraction limiting gasoline sweetening efficiency is the sixth distillation cut of 180℃-end point, containing the isomers of C7 and C8 mercaptan.
