Abstract

The invention discloses a carbon-containing carrier containing cross-linked intercommunicated micron pore channels and a preparation method of the carbon-containing carrier. The preparation method comprises the following steps of: (1) roasting silicon-aluminum composite soil at a high temperature, and treating the composite soil to obtain modified silicon-aluminum composite soil; (2) in the presence of water, uniformly mixing the modified silicon-aluminum composite soil, activated carbon, organic fibers and a binder, and carrying out forming and drying to obtain particles A; (3) dissolving and removing organic fibers in the particles A by using an organic solvent to obtain a material C; and (4) introducing the material C into a caustic soda solution for soaking treatment, filtering out the solution to obtain a material, and washing, drying and roasting the material to obtain the carbon-containing carrier. The carrier obtained by the preparation method is good in mechanical property, has a stepped pore size distribution through pore channel structure, and is beneficial to diffusion and adsorption of organic matters in pore channels.

Description

technical field

[0001] The invention belongs to the technical field of catalytic materials, in particular to a preparation method of a carbon-containing carrier containing cross-linked and interconnected micron pores. Background technique

[0002] The ozone catalytic oxidation process can treat organic pollutant wastewater that is difficult to biochemically degrade COD. Hydroxyl radicals are generated through ozone catalysis, which react with organic pollutants in the sewage, and the pollutants are completely degraded into carbon dioxide and water, thereby removing organic matter in the water. When conventional catalysts treat organic pollutants, the catalytic activity of the catalyst is difficult to achieve the expected effect due to insufficient adsorption activity. In order to further improve the removal rate of organic pollutants, the development of new catalytic materials with high adsorption performance with micro-nano pore structure can efficiently enrich organic matt...
