The solid phase transition pressure swing sorption and the liquid phase complexing sorption integration technology is used to separate paraffin/olefin in the slurry bed reactor. The characterizations of the adsorbents are conducted by the N-2 adsorption/desorption, FT-IR, XRD and TG techniques. The effects of different preparation method, a CuCI loaded coefficient and calcination temperature are studied. The results showed that specific surface area and total pore volume of the adsorbents are significantly decreased when compared to those of SiO, and AC (active carbon). Furthermore, the adsorbents prepared by the impregnation method with SiO2 as carrier, CuCI loaded coefficient of 25.0 wt% and calcinated at 400 degrees C showed higher separation effects. The propylene/propane selectivity coefficient is reached 2.26, and this implied that the feasibility of adsorbents utilized in slurry bed for paraffin/olefin separation.
