摘要：Copper-modified 13 X Zeolite was prepared by impregnation of metal nitrate solution with ion exchange and combined with calcination, and its application in desulfurization of fuel oil was investigated. Different anions have a great influence on the performance of modified adsorbents. Chloride ions are better than nitrate and better than bromide ions. After characterization, the 13 X zeolite modified by different anion copper salts have little influence on the crystal structure of 13 X molecules. Due to the influence of the solubility on the impregnation or the adsorption capacity of the extra nuclear electronic arrangement on the sulfide, the CuCl is significantly better than other ions. Desulfurization performance after calcination is better than that before calcination, and calcination does not oxidize cuprous ions. After optimization, the prepared CuCl-impregnated 13 X zeolite have the best adsorption properties and good reusability.
