Title:
A method for the adsorption separation of Para - xylene from mixed xylene using the manufacturing method of binder Resuzeo light system adsorbent and binder Resuzeo light system adsorbent, and binder Resuzeo light system adsorbent
Document Type and Number:
Japanese Patent JP5972787
Kind Code:
B2
Abstract:
Binderless BaKX zeolitic adsorbents, methods for their production, and processes for their use in a liquid phase adsorptive separation process are provided. An adsorbent includes a binder-converted zeolite portion formed from x wt % kaolin clay binder and (100−x) wt % unconverted Zeolite X with a silica:alumina molar ratio of about 2.5. The kaolin clay binder is in the range of about 10 to about 20 wt %. Ba and K occupy cationic exchangeable sites within the adsorbent. K is in the range of about 0.25 to about 0.9% by weight and Ba is greater than about 31.6% by weight of the binderless BaKX zeolitic adsorbent. Cornstarch may be added to the Zeolite X and kaolin clay binder to increase adsorbent macro-porosity and pore volume. Productivity of the adsorbent is improved decreasing process operating costs. The mechanical strength of the adsorbent is also improved.
