Product introduction:
This product uses high-quality anthracite and tar as raw materials and is processed and refined using advanced technology. Appearance: black columnar particles. It has the characteristics of developed porosity, large specific surface area, strong adsorption force, high mechanical strength, easy repeated regeneration, and low cost. It is widely used in toxic gas purification, waste gas treatment, industrial and domestic water purification treatment, solvent recovery, etc.
The performance indicators of coal-based columnar activated carbon products can be divided into physical indicators (including functional indicators), chemical indicators, safety indicators and other common indicators. Selection and application of activated carbon with four performance indicators
Test method
There are many types of coal-based columnar activated carbon. According to different raw materials, it can be divided into plant-based carbon, coal-based carbon, petroleum-based carbon and other carbons (such as Pulp waste liquid charcoal, synthetic resin charcoal, organic waste charcoal, bone charcoal, blood charcoal, etc.
Our country is a major cigarette production and consumer country. Activated carbon filter cigarettes can greatly improve the filtration effect of smoke and reduce the amount of smoke in the smoke. Harmful ingredients, as a variety of low-toxic cigarettes, will be used in my country in the future
The main purpose of the standard is to unify the quality level of activated carbon used in the entire industry, promote activated carbon production enterprises to improve product quality, and better serve the cigarette industry.
) According to appearance, it can be divided into powdered activated carbon, amorphous granular activated carbon (or broken activated carbon), shaped activated carbon (or shaped granular activated carbon), spherical carbon, fibrous carbon, fabric-like carbon, odorless, and tasteless , insoluble in water and organic solvents, acid and alkali resistant, able to withstand high temperature and high pressure, and is widely used in various fields.
Chemical indicators: ash, moisture, value, heavy metals
Coal-based columnar activated carbon is a carbon with a porous structure, large specific surface area and adsorption capacity. It has developed micropores and has obvious adsorption effect on harmful substances in the gas phase. Activated carbon has stable properties and is non-toxic. The prospect of activated carbon for tobacco use:
Physical performance indicators: strength, specific surface area, particle size distribution, apparent density,
Strength indicators:.
Surface area, iodine adsorption value , phenol adsorption value, carbon tetrachloride adsorption value, etc.
The significance of setting standards for activated carbon for cigarettes:
According to the US "Science News" report, ordinary filter cigarettes made of acetate fiber are not safe. Some literature[] pointed out that filters containing activated carbon can adsorb acetaldehyde, acetonitrile, and isopropyl alcohol in cigarette smoke
. With the deepening of coke reduction and harm reduction work, activated carbon composite filter rods are becoming more and more widely used. Cigarette Use various physical and chemical indicators of activated carbon such as specific surface, particle size, moisture, hardness, ash, value, etc. to review
Properties of coal-based columnar activated carbon:
Activated carbon brings many benefits due to its special physical and chemical properties and huge specific surface Due to its high adsorption and good processability, it is increasingly used in low-tar, high-safety cigarettes, especially
etc. The main chemical performance indicators are: value, ash content, moisture. The safety indicators mainly include iron content, zinc content, lead content, arsenic content and other heavy metal contents. The main adsorption performance indicators are: ratio
piperylene, butanone, benzene, toluene, etc. Extensive and in-depth research has been done internationally on the use of activated carbon to adsorb harmful components in cigarette smoke. It is believed that adding smoke-heavy activated carbon to filter materials has a huge potential market, and the prospects are quite optimistic.
detection capabilities, so the performance indicators of activated carbon for tobacco use selected in the standard are:
When activated carbon is used in filter rods, the main considerations are its adaptability and quality stability during processing. , as well as the smoking quality of cigarettes, based on various reasons, based on the current domestic coal-based columnar activated carbon
The determination of indicators
The processability and inherent quality of closed-mouth rods and cigarettes using composite mouth rods It has a great impact.
The harmful effects of cigarettes are relatively obvious, and it has a good effect on improving the smoking quality of cigarettes. At present, activated carbon for cigarette filters has been developed in China. It complements other filter materials and has main functions
According to its use, it can be divided into gas phase adsorption carbon, liquid phase adsorption carbon, sugar carbon, industrial carbon, catalyst and catalyst carrier carbon. wait.
We provide you with information about Hohhot coal-based columnar activated carbon water purification and gas purification Hohhot coal-based columnar activated carbon manufacturers, and the specific surface area is a comprehensive indicator that reflects the overall adsorption. Therefore, the specific surface area is selected in the standard to represent tobacco use. The adsorption capacity of activated carbon.
B/Determination of strength of wood activated carbon test method
It will definitely receive due attention and development, and will be easily accepted by consumers. At present, my country's activated carbon production has initially formed a relatively complete industrial system. It can be considered that the cigarette industry is likely to be active
and the purified water quality is better than aluminum sulfate coagulant, and the cost of water purification is low compared with it. , floc formation is fast, sedimentation speed is fast, and the processing capacity is larger than traditional products such as aluminum sulfate. . The alkalinity of the consumed water is lower than that of various inorganic coagulants, so no or less alkali agent can be added. , adaptable source water range can be condensed. , low corrosiveness and good operating conditions. , Solubility is better than aluminum sulfate. , the salt content in the treated water increases less, which is beneficial to ion exchange treatment and high-purity water production.

Nutshell activated carbon is widely used in all aspects of industrial and agricultural production, such as alkali-free deodorization (refined demercaptan), ethylene desalted water (refined filler), catalysts in the petrochemical industry Carriers (palladium,
platinum, rhodium, etc.), water purification and sewage treatment, power plant water quality treatment in the power industry and protection of chemical catalysts and carriers in the chemical industry, gas purification, solvent recovery and oil, etc.
Decolorization, Refining of beverages, alcohol, MSG mother liquor and food in the refined food industry, gold extraction in the decolorized gold industry, wastewater treatment in the environmental protection industry, treatment of waste gas
and harmful gases, gas purification and filtration in related industries Mouth, wooden floor moisture-proof, odor absorption, automobile gasoline evaporation pollution control, preparation of various impregnation liquids, etc. Activated carbon will have excellent development prospects and a broad sales market in the future. < Photo/>< />
