Aggregate zeolite adsorbent and its preparation method |
| abstract |
The aggregated zeolite adsorbent of the present invention comprises 95 to 99.5 mass% X zeolite and 0.5 to 5 mass% binder, wherein the exchangeable cation is a Group IIA metal and / or K, and the adsorbent measured by mercury injection method The total pore volume of is at least 0.26 ml / g, and the volume of the pores having a pore diameter of 100 to 500 nm is at least 60% of the total pore volume. The adsorbent is prepared by the following steps: adding a pore former during molding, alkali treating to crystallize in situ, and ion exchange. The adsorbent has high adsorption capacity, fast mass transfer and good mechanical strength and is suitable for adsorbing p-xylene and other alkyl aromatic isomers from mixed C8 aromatic hydrocarbons. |
