The application discloses a system and method for treating high-concentration cyclohexane oxidation tail gas. The system comprises an adsorption / desorption module and an absorption / desorption module, and can directly treat high-concentration cyclohexane oxidation tail gas while meeting the gas emission requirements. The system has the advantages of short overall process, high cyclohexane recovery rate, reasonable energy utilization, low energy consumption and the like.

This invention discloses a V₂O₅-TiO₂ composite honeycomb hollow sphere catalyst and its preparation method. The catalyst is a multilayered hollow sphere formed using V₂O₅-TiO₂ composite oxide as the matrix, wherein the mass ratio of V₂O₅ to TiO₂ is 5:5 to 7:3; the outer diameter of the multilayered hollow spheres is 5 to 20 mm, and the wall thickness is 2 to 12 mm; the sphere walls contain honeycomb-like vertical pores with a pore size of 10 to 50 μm, and the pores account for 15 to 30% of the total sphere wall volume. The V₂O₅-TiO₂ composite honeycomb hollow sphere catalyst of this invention exhibits superior compressive strength and Cl₂ resistance. ‑ The activity retention rate is also significantly reduced, and the desorption temperature and desorption time are also significantly reduced, which can greatly improve the desorption efficiency of amine solution after absorbing saturated CO2.
