  • Publication number: 20230405547
    Abstract: A m-xylene adsorbent contains 94 to 99.9 wt % of a Y molecular sieve and 0.1 to 6 wt % of a matrix. The Y molecular sieve consists of a non-crystal-transformed Y molecular sieve and a Y molecular sieve produced by a crystal transformation. The non-crystal-transformed Y molecular sieve is a mesoporous nano Y molecular sieve, which has a crystalline grain size of 20 to 450 nanometers, contains two types of mesoporous pores, and respectively has most probable pore diameters of 5 to 20 nanometers and 25 to 50 nanometers. The adsorbent is used for adsorptive separation of m-xylene from mixed C8 aromatic hydrocarbons.
