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.
