摘　　要：以工业戊烷为原料,在萃取温度15℃、静置时间15min、剂油比1:1的条件下,考察多种萃取剂的萃取脱硫性能。实验结果表明,糠醛和NaOH溶液作为单一萃取剂的效果较好,可将工业戊烷中的硫含量由原来的40.3mg/L降低到1.0mg/L;5%NaOH溶液与95%乙醇在较宽的体积比范围内进行复配可将戊烷中硫含量降低到1.0mg/L;当N,N-二甲基甲酰胺与5%NaOH溶液按照体积比为1:1进行复配时,可将戊烷中的硫含量降低到1.0mg/L,但N,N-二甲基甲酰胺含量过高则会抑制复合萃取剂的脱硫效果。The desulfurization performance of several extraction agents were studied using industrial pentane as feed under the conditions of an extraction temperature of 15℃, a settling time of 15 min and an agent to oil ratio of 1. Test results indicated that： （1） As to single extraction agent, furfural and NaOH solution are preferred, which can reduce the sulfur content of pentane from 40.3 mg/L to 1.0 mg/L; （2） 5%NaOH solution and 95% ethanol could be formed composite agent in rather wide volume ratios, which can reduce the sulfur content of pentane to 1.0 mg/L; （3） Composite agent of DMF and 5%NaOH mixing with a volume ratio of 1 can reduce the sulfur content of pentane to 1.0 mg/L, yet exceeded amount of DMF in composite agent might suppress the removal of sulfides from pentane.
