摘要：

In order to explore the adsorption mechanism of different adsorbents for different adsorbents in a rotating packed bed (RPB), the experiments of adsorbing different adsorbents (resorcinol, phenol, and nitrobenzene) by different adsorbents (AC, silica gel, and molecular sieves) are studied. The adsorption performance of different adsorbents on different adsorbents in a high gravity environment is compared. The experimental results show that the adsorption capacity of AC for resorcinol was 7.02 and 4.45 times that of silica gel and molecular sieve in the same conditions. The adsorption rate and adsorption effect of AC on nitrobenzene are better than that of phenol and resorcinol. The adsorption capacity of AC to nitrobenzene is increased by 6.71% and 1.78% compared with that of phenol and resorcinol, respectively. RPB can more effectively improve the adsorption rate and adsorption capacity than the fixed bed. The pore structure and surface-active components of the adsorbent have a certain effect on different adsorbents, and the adsorption equipment also affects the adsorption performance.
