The present invention provides a method for separating HBr from HBr-containing hydrocarbons (alkenes, aromatics and/or alkanes) to purify the hydrocarbons. Reacting a silica supported metal oxide solid material (MOx/SiO2, MOx=MgO, CoO, Co2O3, CuO and mixture thereof) with HBr in HBr-containing hydrocarbons, so as to ensure that the concentration of HBr is reduced to below 1.87×10-16, and then oxidizing the solid material which reacted with HBr in oxygen or air to regenerate MOx/SiO2, meanwhile Br2 is recycled. Therefore, the purpose of continuous purification of hydrocarbons can be achieved.
本发明提供了一种从含HBr的烃(烯烃、芳香烃和/或烷烃)中分离HBr以纯化烃的方法。将硅负载的金属氧化物固体材料(MOx/SiO2,MOx=MgO、CoO、Co2O3、CuO和其混合物)与含HBr的烃反应,以确保HBr浓度降至低于1.87×10-16,然后在氧气或空气中氧化与HBr反应的固体材料以再生MOx/SiO2,同时回收Br2。因此,可以实现烃的持续纯化的目的。
