| 摘 要： | 应用均匀设计法制定甲醇－碱水溶液萃取脱除ＦＣＣ汽油硫醇的试验方案，并对试验结果进行回归处理，建立脱硫醇的数学模型，得出最佳值：溶剂组成，７．２％ＮａＯＨ、９０．０％ＣＨ３ＯＨ；油剂体积比１．０；脱臭率９６．８％。验证结果表明，模型的预测值与试验值能很好吻合，通过对等值线图等条件的分析，确定出萃取脱硫醇的最佳操作区间：溶剂组成，５．０％～１０．０％ＮａＯＨ、７８．０％～８５．０％ＣＨ３ＯＨ；油剂体积比１．０～２．０；脱臭率≥９３．０％。

| Abstract: | A test scheme of mathanol/alkali solvent extraction for sweetening of FCC naphtha was determined by uniform design. The test results were handled by regression, and a mathematical model of sweetening was established. The calculated optimal conditions were at a solvent composition of 7.2% NaOH with 90.0% CH 3OH and a naphtha/solvent volume ratio of 1.0, and the calcualted sweetening rate was 96.8%. The varifying test results showed a well identity between the calculation and the experimentation. The optimal area was obtained from the isoline chart, at a solvent composition of 5.0% to 10.0% NaOH with 78.0% to 85.0% CH 3OH and a naphtha/solvent ratio of 1.0 to 2.0 resulted a sweetening rate higher than 93.0%. |
