A series of CaO-Al₂O₃ composites with different CaO contents were prepared by co-precipitation from low-price Ca and Al precursors, and characterized by XRD, TG-DTG, N₂ adsorption, SEM and etc. Their performance removing HCl from reformate was evaluated by dynamic absorption method. Due to its large surface area, uniform particle size and high porosity, CAO-1 showed the best dechlorination performance. When the initial content of chlorine in reformate is less than 15 ng/μL, the dechlorination capacity can reach to 18% at a LHSV of 3 h^-1 at 55 ℃.
