Experiments were performed using 7 adsorbents (K-A, Na-A, Ca-A, Ca-X, Na-X, Na-Y, and Na-ZSM5 zeolite molecular sieves) and 3 adsorbents (benzene, methanol, n-hexane). the study. By studying the static adsorption of adsorbents by A-type and X-type molecular sieves, the results show that molecules with a kinetic diameter smaller than the pore size of the molecular sieve are more easily adsorbed, and the molecular sieve adsorbs more polar molecules than non-polar molecules (methanol> benzene > n-hexane), using different AlO4 content (Na-X, Na-Y, Na-A and Na-ZSM5) and different balanced cations (K-A, Na-A, Ca-A and Ca-X, Na-X) molecular sieves Microwave desorption shows that the AlO4 content of the molecular sieve and its equilibrium cations have a significant effect on its microwave desorption effect (Molecular sieves with high AlO4 structure content are more suitable for microwave desorption, and molecular sieves with balanced cations Na + have strong wave absorbing ability For K + and Ca2 +).
