摘　　要：将CuSO_4·xHCl加到石油馏份中,在常温、常压下充分接触,油中的各类硫化物与CuSO_4·xHCl形成不溶于油的络合物而除去。对各类硫化物进行的实验研究结果表明,硫醚与CuSO_4·xHCl的络合效果最好。因此,该方法最适用于含硫醚的石油馏份的脱硫。A new method of desulfurization of petroleum distillates was proposed.At room temperature and atomosphere,petroleum fractions were treated with CuSO4 xHCl,and various sulfur-containing compounds formed complexes with CuSO4 xHCl.TheComplexes can not dissolve in the oil and connot be removed.The results of experimentshowed that the sulfides are easier to combine with CuSO4 xHCl.So the method can be used for desulfurization of sulfides-containing sulfides distillates efficiently.
