Embodiment 1

[0031] A kind of preparation method of the gac used for hangover of the present invention, comprises the following steps:

[0032] Step A: using moso bamboo that is more than 4 years old, taking the hard part in the middle as raw material; carbonizing the above raw material in an externally heated carbonization furnace at a temperature of 600°C to 900°C, carbonizing for 10 to 20 hours, and crushing after carbonization; The carbonized material is activated by heating and feeding high-temperature steam. The carbonized material rolls slowly forward in the activation chamber. The raw material after carbonization is activated, the activation temperature is 850°C-900°C, and the activation time is 4 hours. Customized activated carbon with a certain pore size distribution and specific surface area; the customized activated carbon has a pore volume of 0.35 to 0.6 cm with a pore size below 1.0 nanometers 3 / g, the pore volume between 1.0 nanometers and 25 nanometers is 0.45~0.60cm 3 / ...

Embodiment 2

[0037] A kind of preparation method of the gac used for hangover of the present invention, comprises the following steps:

[0038] Step A: Use northeast red pine wood as raw material; carbonize the above-mentioned raw material at a temperature of 500°C to 600°C for 5 hours, and then crush it after carbonization; activate the carbonized material by indirect external heating and introducing high-temperature steam, and the carbonized material is in the The activation chamber slowly rolls forward, and the direction of the high-temperature water vapor is the same as that of the carbonized material, so that the high-temperature water vapor and the carbonized material are fully contacted for activation. The activation temperature is 860 ° C ~ 930 ° C, and the activation time is 6 hours. Customized activated carbon with a certain pore size distribution and specific surface area; the pore volume of the customized activated carbon with a pore size below 1.0 nm is 0.35-0.60 cm 3 / g, the po...

Embodiment 3

[0043] A kind of preparation method of the gac used for hangover of the present invention, comprises the following steps:

[0044] Step A: using moso bamboo more than 4 years old, and taking the hard part in the middle as raw material;

[0045] The above raw materials are carbonized in an externally heated carbonization furnace at a temperature of 700°C for 10 to 25 hours, and then crushed after carbonization; the carbonized materials are activated by indirect external heating and high-temperature steam, and the carbonized materials are slowly heated in the activation chamber. Rolling forward, the direction of introducing high-temperature water vapor is the same as that of the carbonized material. The high-temperature water vapor makes full contact with the carbonized material for activation. The activation temperature is 850 ° C to 900 ° C, and the activation time is 5 hours. Customized activated carbon with a certain pore size distribution and specific surface area; the pore...

Abstract

The invention provides a method for preparing active carbon for relieving or neutralizing the effect of alcohol. The method comprises: using wood, shells, mao bamboo or coal as raw material, to customize active carbon with certain aperture distribution, of which the specific surface area is 1100-2000m2 / g, refining the customized active carbon, and adding 8-20% of aqueous alkali and the active carbon into a reaction vessel; introducing steam to heat the aqueous alkali until the temperature rises to 90+-5 DEG C, insulating, and dehydrating when the temperature falls up to less than 55 DEG C; washing with tap water and then dehydrating for several times; adding the dehydrated material into 6-15% of acid solution for pickling, introducing steam to heat the acid solution until the temperature rises to 65+-6 DEG C, insulating, adding cold water, and dehydrating when the temperature falls up to less than 55 DEG C; washing with tap water and then dehydrating for several times; washing with pure water and then dehydrating, to regulate the pH value in a range of 6.5-9.5. The active carbon prepared by the method has an obvious effect for relieving or neutralizing the effect of alcohol, accords with the standard of GB / T 13803.4-1999 of activated carbon for refinement of injection and the standard of medicinal charcoal in the Chinese Pharmacopoeia: 2010 edition, and accords with an edible hygienic standard.

Description

technical field [0001] The invention relates to a method for preparing activated carbon, in particular to a method for preparing activated carbon for relieving alcohol. Background technique [0002] Activated carbon is widely used in various fields of the national economy, environmental protection and all aspects of people's daily life, and is suitable for refining and purification in the production process of food and medical sanitation, all of which stem from the strong adsorption of activated carbon , adsorption performance and excellent chemical stability. The adaptability of adsorbate and adsorbent, the relationship between the selective adsorption of activated carbon and its pore size distribution characteristics, force people to continuously improve the regulation technology of activated carbon pore structure characteristics. [0003] Oral activated carbon can absorb some toxic and harmful substances in the digestive system of the human body, so as to prevent them fr...
