摘要

摘要: 采用低廉的铝盐和钙盐,通过共沉淀法制备了一系列不同CaO含量的CaO-Al₂O₃复合氧化物,并用XRD、TG-DTG、N₂吸附-脱附、SEM等手段对其进行表征。结果表明,制备的复合氧化物两相分布均匀、孔隙率较高、存在较多的介孔和大孔,比表面积也较大。采用动态吸附法将制备出的复合氧化物应用于重整生成油中氯化氢的脱除反应中,结果表明,高比表面积和大孔容的CAO-1具有最佳的HCl脱除效果,当反应温度为55 ℃、液空速为3 h^-1,重整生成油中氯含量小于等于15 ng/μL时,其氯容可达到18%。

Abstract: 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 ℃.
