Embodiment 1

[0015] Example 1: A preparation method of activated reed bamboo charring and pore formation is as follows:

[0016] (1) Carbonization process, in order to avoid the influence of impurities in the raw materials, the reed bamboo should be washed with water before use to remove the impurities on the surface, after filtering the water, crush it to take the reed bamboo with a particle size of 1.0cm, and dry or dry it. . Then it was dried in an oven at 100℃ for 7 hours. The dried reed bamboo was carbonized in a high-temperature furnace, isolated from the air, heated to 340℃, and kept at a constant temperature for 1 hour to obtain the reed bamboo carbonized material.

[0017] (2) The activation process is to prepare activated carbon with the charred reed bamboo material as the raw material and steam as the activator. The charred reed root charred material is added to the activation furnace, heated to 100°C, and then injected into the water vapor. Keep the amount of water vapor inflow sta...

Embodiment 2

[0018] Example 2: A preparation method of activated reed bamboo carbonization and pore formation is as follows:

[0019] (1) Carbonization process, in order to avoid the influence of impurities in the raw materials, the reed bamboo should be washed with water before use to remove the impurities on the surface, after filtering the water, pulverize it and take the reed bamboo with a particle size of 2.0cm, and dry or dry it. . It was then dried in an oven at 120°C for 9 hours. The dried reed bamboo is carbonized in a high-temperature furnace, isolated from air, heated to 360°C and kept at a constant temperature for 2 hours to obtain a reed carbonized material.

[0020] (2) The activation process is to prepare activated carbon with charcoal charcoal as raw material and steam as activator, add charcoal charcoal from charcoal roots into the activation furnace, heat up to 120°C, and pass water vapor. Keep the amount of water vapor inflow stable (water vapor flow rate is 3kg / h), heat to ...

Abstract

The present invention relates to adsorbent, and belongs to the field of technology of treating water and air with active carbon. The present invention prepares active carbon with giant reed root and stem and through crushing, stoving, carbonizing, forming pore and activating. The prepared active carbon may be applied widely in eliminating aromatic compound and organic chloride from waste water, eliminating heavy metal ions, treating atmosphere pollution, etc. The giant reed has low carbonizing temperature and low power consumption.

Description

Technical field [0001] The invention relates to an adsorbent, which belongs to the technical field of activated carbon water treatment and waste gas and harmful gas treatment. Background technique [0002] As an inorganic chemical product, activated carbon has its unique characteristics. It has strong adsorption capacity for organic or inorganic substances in gas and solution, and it can also be used as a filler. Because of its unique pore structure and surface-active functional groups, sufficient chemical stability, mechanical strength, acid, alkali, and heat resistance, as well as insoluble in water and organic solvents, it is easy to regenerate after use and has good properties, such as water treatment It has a wide range of uses in the treatment of waste gas and harmful gases. [0003] Activated carbon currently produced is roughly divided into two types: wood and coal. In some areas, cutting down trees to obtain activated carbon has caused serious forest destruction and soil...
