An extraction distillation desulfurization for cyclopentane is proposed when using sodium hydroxide solution as the extractant. Effects of alkali concentration, the ratio of catalyst to oil, reflux ratio and assistant solvent on the desulfurization are discussed. Results showed that the sufur content reduced to the lowest of 0.13mg/L, where the desulfurization ratio reached to 97.8% under the optimal conditions. The optimal conditions are composed of a column in the stripping section, 4% of sodium hydroxide concentration, 4 : 3 of catalyst to oiland 1 : 5 of flux ratio.
