Title:
META-XYLENE ADSORBATE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/078362
Kind Code:
A1
Abstract:
A meta-xylene adsorbate, comprising 94-99.9 wt% of Y molecular sieve and 0.1-6 wt% of matrix. The Y molecular sieve consists of a non-crystal transformed Y molecular sieve and a Y molecular sieve generated by crystal transformation. The non-crystal transformed Y molecular sieve is a mesoporous nano-Y molecular sieve. The mesoporous nano-Y molecular sieve has a grain size of 20-450 nanometers, and contains two mesoporous channels, and the most probable pore diameters are respectively 5-20 nanometers and 25-50 nanometers. The adsorbate is used for adsorbing and separating meta-xylene from mixed C8 aromatic hydrocarbon, and has good mass transfer performance and higher meta-xylene adsorption selectivity and adsorption capacity.
