Abstract

The invention discloses a method for preparing high-adsorption-capacity crystal glue microsphere particles and belongs to the technical field of adsorption materials. Semi-coke and sludge are taken asraw materials to prepare high-adsorption particles, and under the dehydration, wetting-expansion and condensation functions in the preparation process, aromatization of a carbon skeleton is promoted,and the carbon content and the adsorption performance are improved; and during filling of a crystal glue material, the adsorption efficiency of the material is effectively improved, and the adsorption capacity of the crystal glue material is improved. As a carbon material with a porous structure is added into the crystal glue material, a cross-linking agent in a polymerization system is adsorbedby the carbon material; when the temperature of a reaction system is reduced to be lower than the solvent crystallization temperature, a solvent starts to crystallize, and at the moment, polymer monomers and the cross-linking agent are enriched nearby the adsorption material; and therefore, the forming rate and the pore forming ratio of the crystal glue material are improved, and the adsorption capacity of the crystal glue material is further improved.

Description

technical field [0001] The invention discloses a preparation method of crystal colloid microsphere particles with high adsorption capacity, and belongs to the technical field of adsorption materials. Background technique [0002] With its unique ultra-large pore structure with a pore size of several microns or even hundreds of microns, crystal colloidal media has attracted more and more attention, and the research on crystal colloidal media has also become increasingly in-depth. The continuous bed crystal gel chromatography method based on this method uses crystal gel with super large pores as the separation medium, which can directly separate biological substances from complex feed liquids at high flow rates, and realizes centrifugal separation, filtration, and concentration. Integrate several separation steps such as product trapping into one step. Crystal gel microspheres are ultra-macroporous polymer microsphere materials prepared based on crystal gel solvent pore-formi...
