5results about How to "Improve desorption efficiency" patented technology

This invention provides a lithium adsorbent and its preparation method. The lithium adsorbent comprises: a binder framework and a lithium-ion sieve precursor located on at least a portion of the surface of the binder framework. The binder framework has a mesh-like interconnected pore structure, and the sphericity of the lithium adsorbent after grinding is not less than 95%. The lithium adsorbent provided by this invention, due to the mesh-like interconnected pore structure of its binder framework, avoids the formation of a dense skin layer on the surface of the lithium adsorbent and effectively increases the contact area between the lithium-containing liquid and the lithium-ion sieve, thereby significantly improving the adsorption and desorption efficiency of lithium.

This application discloses a multi-stage cyclone-type organic waste gas adsorption and purification system. In this system, organic waste gas passes sequentially from bottom to top through the first blades of the first cyclone plates in each layer, forming a rotating mixed flow with the powder adsorption particles on the corresponding first blind plates. The gas and solid phases are in full contact, and the organic components in the gas phase are fully adsorbed by the micropores of the solid. Through multi-stage adsorption, the organic waste gas is effectively purified to meet emission standards. The adsorption-saturated powder adsorption particles are restored to adsorption power by a dual-circulation cyclone desorption and regeneration device and then reintroduced into the multi-stage cyclone-type adsorption and purification device for repeated use.

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.
