Does anyone know how to make activated charcoal?

Activated carbon has a well-developed pore structure, and the adsorbed molecules enter the adsorption pores through the macropores (R 50nm) and mesopores (2nm R 50nm) through the two transportation channels Micropores (R 2nm), and the molecules and surface groups on the pore surface are combined together by van der Waals force to complete adsorption. Founded in 1996, Nanjing Mulinsen Carbon Industry Co., Ltd. is a professional activated carbon production enterprise integrating scientific research, development, production and sales. Over the past 20 years, the company has been focusing on the production of activated carbon, and has now developed into a subsidiary of Nanjing Mulinsen (deep processing base, mainly producing high-end products such as high-grade pure activated carbon and activated carbon catalysts), Hainan Mulinsen (Southeast Asia coconut shell raw material base, mainly producing coconut shell activated carbon), Gansu Mulinsen (Northwest coconut...).

Activated carbon can be obtained by dry distillation of walnut shells, cottonseed shells or peanut shells, etc., and then activated treatment.

1. Activated carbon will drop toner more or less, which is normal. Generally, after we buy back activated carbon, we have to clean it once. The best water for cleaning activated carbon is pure water, because tap water contains calcium, magnesium and other substances, which will be absorbed by activated carbon.

If you use tap water, wash it and wash off the toner on the surface, not for too long, so as not to let the activated carbon absorb too much calcium and magnesium in the water.

2. The activated carbon should be replaced once a month or so, because the activated carbon has lost its effect due to absorbing too much impurities. There is a way to restore the failed activated carbon, which is to expose the activated carbon to the sun, which can restore the absorption of activated carbon, but the activated carbon should not be reused many times, and it is recommended to replace the activated carbon at least once every two months.

1. Choose activated carbon with strong adsorption capacity.

Not all activated carbon adsorption effects are the same, only those with a large number of pore sizes slightly larger than the diameter of harmful gas molecules have strong adsorption capacity.

2. Place activated carbon indoors reasonably.

Personally, I think that the placement of activated carbon should not affect the indoor appearance, and the second should be placed in the most polluted place, such as: in the wall cabinet in the room, behind the sofa in the living room, etc.

3. Regularly release harmful substances in activated carbon.

Harmful gases are often only adsorbed in the activated carbon and do not decompose, so after using activated carbon for a period of time, the activated carbon should be exposed to the sun, which can release some toxic substances.

4. Replace activated carbon in time.

The adsorption of activated carbon is saturated, at this time the activated carbon not only has no adsorption effect, but also may release the toxic substances in it, if the indoor pollution is serious, it is recommended that the activated carbon is discarded after 2-3 weeks of use.

Precautions. The effect of activated carbon in controlling air pollution is relatively slow, and the purpose of removing pollution cannot be achieved in a short time.

There are many kinds of contamination in the room, and ordinary activated carbon packs cannot have the effect of removing them completely.

I am glad to answer for you, the activated carbon production process is roughly divided into: carbonization, cooling, activation, washing and a series of processes. The shape of the finished product of activated carbon production is roughly divided into:

granular, columnar, powdery, etc. Use firewood to make charcoal, then knock it into a small piece of charcoal of about 1cm3, put the small piece of charcoal into a clean fine nylon mesh bag, pierce it to the mouth of the bag, and then put it into a household pressure cooker or medical pressure cooker containing 5% sodium carbonate solution, and boil at high pressure for about 30 minutes to wash out the oil and dredge the micro holes in the charcoal. To prevent the charcoal from floating on the sodium carbonate solution, a clean stone can be tied to the outside of the nylon bag and fall down.

After boiling, rinse the charcoal twice with water to remove the oil, then put it in a 5% sodium carbonate solution and boil it at high pressure for about 30 minutes, and rinse it three times with about 80 water after taking it out to wash the oil quality of the potatoes and the amount of sodium carbonate in less answer. Finally, boil with water at high pressure for about 30 minutes to further dredge the micropores in the charcoal; Remove and dry to obtain activated charcoal, and bake it before use for best results. The adsorption capacity of this method is much higher than that of charcoal.

Used activated carbon can also be regenerated using this method. Extended information, I hope mine can help you! <>
