Asphalt resin composite-based spherical activated carbon with fast absorption effect enhanced and preparation method thereof

Abstract

The invention discloses asphalt resin composite-based spherical activated carbon with a fast absorption effect enhanced. The asphalt resin composite-based spherical activated carbon is characterized by comprising, by weight, 41-45 parts of tert-butyl methacrylate, 40-43 parts of ortho-position alpha methyl styrene, 2-3 parts of azodiisobutyronitrile, 1.5-2 parts of ethylene glycol dimethacrylate, 25-28 parts of glyceryl stearate, 2-3 parts of polyvinylpyrrolidone, a proper amount of distilled water, a proper amount of acetone, 25-28 parts of sulfonated bitumen powder, 4-5 parts of shell activated carbon, 2-3 parts of kaolin, 2-2.5 parts of N-methyldiethanolamine, 8-9 parts of acetum with the concentration being 50%, and 3-4 parts of corn starch. According to the asphalt resin composite-based spherical activated carbon, the matching of resin content and surface layer permeable asphalt content is scientific, the total pore volume and the mean pore size of the spherical activated carbon can be increased, and the mechanical strength can further be effectively improved; the components such as modified kaolin and corn starch are added through a special technology, so that the rate of absorption is further increased, and a wider application prospect is achieved.

Description

technical field [0001] The invention relates to the field of materials, in particular to a rapid adsorption enhanced asphalt resin composite-based spherical activated carbon and a preparation method thereof. Background technique [0002] Spherical activated carbon has been widely used in related fields such as medicine, environmental protection and catalyst carrier because of its good sphericity, high packing density, less particle shedding and fast adsorption and desorption speed. Spherical activated carbon is mainly divided into three categories according to different raw materials: coal-based spherical activated carbon, polymer resin-based spherical activated carbon and pitch-based spherical activated carbon. Among them, coal-based spherical activated carbon has the advantages of cheap raw materials and wide sources, but coal-based activated carbon has high ash content, many impurities, and low mechanical strength, which limits its application and development.
