Problems solved by technology

[0003] Activated carbon prepared from starch polysaccharides has good activity and adsorption, but its molding is poor, and binders such as tar need to be re-added for molding
[0004]At the same time, general activated carbon does not have a good adsorption effect on small molecule organic matter, and it is easy to release it at a slightly higher temperature, resulting in poor air purification effect

Embodiment 1

[0018] A method for preparing an air-purifying activated carbon adsorption material, comprising: uniformly mixing sorghum flour and zinc chloride, adding to cold water, beating uniformly, heating to 95 degrees under stirring, adding sodium hydroxide, and keeping the temperature open 3 hours, stop stirring, heat to 155 degrees, keep warm for 3 hours, after solidification, cool, cut the solidified material into the same size, put it in a high-temperature furnace, and calcine it in a nitrogen atmosphere. After calcination, put the material Put it into 10% hydrochloric acid water, heat to 60°C, shake and wash slowly, then rinse with water until neutral drying.

[0019] The mass ratio of sorghum flour, zinc chloride and water is 1:1:3. The molar ratio of zinc chloride to sodium hydroxide is 1:1. The preparation method of the air-purifying activated carbon adsorption material is characterized in that the solidified material is cut into strips of 5 cm×1 cm×1 cm in the same size. Th...

Abstract

The invention discloses a preparation method of an air purification activated carbon adsorption material, which comprises the following steps of: well mixing sorghum flour and zinc chloride, adding the mixture into cold water, uniformly pulping, heating to 90-100 DEG C in a stirring state, adding sodium hydroxide, carrying out open heat preservation for 2-4 hours, stopping stirring, heating to 150-160 DEG C, carrying out heat preservation for 2-4 hours, solidifying, cooling, cutting the solidified material into parts with the same size, putting the material into a high-temperature furnace, calcining in a nitrogen atmosphere, putting the calcined material into 10% hydrochloric acid water, heating to 60 DEG C, slowly oscillating and washing, then rinsing the material with clear water until the material is neutral, and drying the material.

Description

technical field [0001] The invention belongs to the field of production technology of air-purifying activated carbon adsorption materials, and in particular relates to a preparation method of air-purified activated carbon adsorption materials. Background technique [0002] Activated carbon is a porous artificial carbon adsorbent made of carbon-containing substances after carbonization and activation. It has a well-developed pore structure and a huge specific surface area, and can be used as an adsorbent, catalyst and catalyst carrier. Activated carbon, as a man-made material, was invented from 1900 to 1901. Its inventor was Rafael Wang Osterleko, who obtained a patent by using chemical activation and physical activation to manufacture activated carbon. Activated carbon was produced industrially for the first time in 1911 by Dr. Mengaud at his factory near Vienna. The product at that time was powdered activated carbon, which was the first industrial production plant in the ...
