| Abstract: | The possibility of using activated carbon to remove sulfur containing species in oil was explored. The desulfurization performance of activated carbons pretreated under different conditions was evaluated by measuring the adsorption isotherms and using a model oil in a batch type adsorption device. The sulfur content in the model oil is 440×106. The results show that the adsorption capability of thiophene on the activated carbon pretreated by oxidizing in HNO3 at 120 ℃ is superior to that of other activated carbons treated by other methods. The optimum adsorption performance can be achieved at the temperature of 20 ℃, the adsorption time of 3 h, and the adsorbent/ oil ratio of 0.09 g/g. The adsorption isotherms of thiophene on the activated carbons fit the Freundlich model and equation satisfactorily. The thiophene adsorption on the activated carbon is a spontaneous. |
