Embodiment 1

[0051] Example 1, such as figure 1As shown, a kind of activated carbon, the activated carbon is a columnar body 1 with a circular cross section, the length is 3-7mm, the central position has a through hole 2 that runs through the columnar body 1, the diameter of the through hole is 0.5-1.5mm, and the diameter of the activated carbon is 3mm. -5mm. BET specific surface area is 1085-1310m 2 / g, specific pore volume 0.4-0.8cm 3 / g, mesopore volume 0.5-0.61cm 3 / g; the average pore size of the activated carbon is 25.7-31.5nm, the strength is greater than 95%, and the bulk weight is 400-480g / L.

[0052] Columnar hollow activated carbon should be understood as special-shaped activated carbon with high BET specific surface area, high total pore volume, high and medium pore volume and appropriate pore diameter.

[0053] The columnar hollow activated carbon has micropores and mesopores. Micropores are pores with a diameter less than 2nm; mesopores are pores with a diameter greater t...

Abstract

The invention discloses an activated carbon, which is a columnar body with a through hole passing through the columnar body; the diameter is 3-5mm, the length is 3-7mm, and the diameter of the through hole is 0.5-1.5mm. The columnar hollow activated carbon is used as a catalyst The adsorption capacity of the carrier is strong, which improves the use efficiency of the catalyst, and the gas conversion rate is greatly improved, reaching 98.8%. The forming mold can increase the adsorption area of ​​the activated carbon and reduce the production cost and ensure that the surface of the hollow activated carbon is not easy to be scratched; The feed hole provides enough material for hollow activated carbon molding; when the activated carbon is damaged due to friction and wear with the inner wall of the pipeline, only the cylindrical member needs to be replaced instead of the entire forming mold, which can save production costs; the molded hollow activated carbon can be guaranteed. The inner and outer surfaces are scratched.

Description

technical field [0001] The invention relates to an activated carbon, in particular to a hollow activated carbon, a preparation method and a forming mold, and belongs to the technical field of activated carbon. Background technique [0002] It is known that the existing activated carbon materials have a large number of pores, a high specific surface area, and a variety of active functional groups on the surface, which have good catalytic activity, not only that, but also have good chemical stability and high mechanical strength. , can be used repeatedly, these excellent characteristics make the existing activated carbon material a high-quality adsorbent that has attracted worldwide attention. Activated carbon has been used in decolorization, anti-virus and deodorization in food and medicine for a long time, and as time goes by, they are more and more widely used in industry, national defense and medicine as high-quality adsorbents and catalyst carriers. Sanitation, chemical ...
