【Abstract】 The previous research proves that removal activity for H₂S by solid base is high.The removal activity for organic sulfur compounds by solid base was studied.The results show that the solid base has a certain extent removal activity for these compounds.Mercaptans are removed easily.The stronger acidity and polarity of mercaptan,the more easily it is removed.Thiophenes are most difficult to be removed due to their weak polarity and large space obstruction.The order of removal efficiency of these compounds is approximately as follows: mercaptan>carbonyl sulfide>sulfide>disulfide>thiophenes.更多还原
