Matters needing attention when purchasing coal based coconut shell activated carbon

Precautions for the purchase of activated carbon for coal-based columnar activated carbon carbon:

1. The packaging of coal-based columnar activated carbon is best sealed packaging. Because the air is more or less diffused with a variety of organic macromolecular substances, especially in the newly renovated store or the storage cabinet at home in the phenolic substances concentration is very large, these substances will be adsorbed by the activated carbon, over time, the adsorption performance of the activated carbon will be reduced or even unusable because of the adsorption of these substances. Therefore, the higher the adsorption value of activated carbon, the more it should be sealed to prevent the performance of activated carbon from being interfered with by the outside world.

2. Some of the counterfeit activated carbon that appears on the market is passed off as a semi-finished product of activated carbon, and the carbonized material can only become real activated carbon after the "activation" process, and the activation process is the most important process of manufacturing pore structure in the activated carbon manufacturing process. The carbonized material lacking this process can be said to have almost no adsorption performance, which makes consumers suffer a lot. Because the carbonized material does not have the process of activating and forming pores, the surface is smoother than the activated carbon, and the color is whitish, slightly metallic, the feel is harder than the activated carbon, and the weight is much heavier.

There is also a considerable part of the counterfeit activated carbon using inferior raw materials diatomaceous earth firing, its carbon content is very low, most of them are inactive substances, this carbon color is relatively white, the feel is very heavy, the length of the particles is longer, the strength is also very high, colliding with each other will make a crisp sound similar to ceramic percussion, and it will be found that there are white fine particles on the section when broken by hand.

Coal columnar activated carbon is a very excellent adsorbent, which is made of charcoal, bamboo charcoal, various husks and high-quality coal as raw materials, and processed and manufactured by a series of processes such as crushing, screening, catalyst activation, rinsing, drying and screening of raw materials through physical and chemical methods. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in the gas phase and liquid phase to achieve the purposes of decolorization and refining, disinfection and deodorization, decontamination and purification. Briquette-based columnar activated carbon is widely used in solvents, industrial waste gas purification, protective equipment, home improvement air purification, power plant raw water purification, drinking water purification, reclaimed water reuse, etc.

Type II coal-based columnar activated carbon is widely used in pure water treatment, power plant raw water treatment, electronics plant water treatment, chemical pigment water treatment, food factory and pharmaceutical factory water treatment, as well as sewage plant biological carrier, waste gas treatment of factories and garbage dumps, reclaimed water reuse, marine aquaculture and seedlings, etc. Briquette columnar activated carbon is widely used in pure water manufacturing, sewage treatment, sewage biological carriers, marine aquaculture, as well as cold storage preservation, factory air purification and other fields.

Coconut shells are more expensive, and coal quality is cheaper!

Coal-based activated carbonIt is made of high-quality coal as raw material, refined with advanced process equipment, and refined through a series of processes such as carbonization, cooling, activation, and washing. The shape is divided into granular, columnar, powdery, etc.

Advantages: low and large reserves of raw material resources.

Disadvantages: It is difficult to make high-performance activated carbon with high impurities, and it is difficult to apply it to high-demand fields. Its appearance is generally black cylindrical activated carbon, amorphous crushed carbon, generally made of powdered raw materials and binders through kneading, extrusion, and then carbonization, activation and other processes.

It can also be extruded with powdered activated carbon and binder. In recent years, with the increase in coal prices, the advantages have slowly receded, and they have been gradually replaced by wood and coconut shell products.

Woody activated carbon

Wood activated carbon is made of high-quality wood powder as raw material, the shape is powdery, columnar, granules through high temperature carbonization, granulation, activation and a variety of processes refined into wood activated carbon, with the progress of technology, the first domestic use of non-bonded molding activated carbon proprietary technology, made of wood columnar, wood pellets and other granulated activated carbon.

Advantages: large specific surface area, high activity, low ash impurities, developed mesopores, strong decolorization, large pore structure, etc.

Disadvantages: **High, limited resources. Gradually replace coal-based columnar activated carbon for organic solvents, air purification, motorcycle carbon canisters, oil and gas, organic waste gas treatment, protection, gas desulfurization and deodorization, catalysts and carriers and other fields, and traditional wood powdered activated carbon is used for decolorization for various purposes.

Activated carbon for husks

Fruit shell activated carbon is mainly made of fruit shells (common coconut shells, apricot shells, cherry shells, jujube shells, walnut shells, olive shells, etc.) as raw materials, and is carbonized, activated and refined.

Pros: Lower.

Disadvantages: low strength, difficult to apply to high-demand fields. Compared with coconut shell charcoal, the quality is not as good as coconut shell charcoal, but ** is lower.

Coir activated carbon

Coconut shell activated carbon is one of the best quality in the fruit shell charcoal, imported high-quality coconut shell as raw material to produce amorphous granular carbon by water vapor method, the shape is amorphous granular or columnar, with high mechanical strength, developed pore structure, large specific surface area, fast adsorption speed, high adsorption capacity, easy to regenerate, durable and other characteristics.

Advantages: strong adsorption, high strength, low impurities.

Disadvantages: Affected by the import of raw materials, it is relatively high. It is mainly used for catalyst and catalyst carrier, gold extraction of cyanide gold ore, as well as drinking water purification, monosodium glutamate industrial solution refining, food, beverage, wine, air purification activated carbon and high-purity drinking water deodorization, removal of heavy metals in water, chlorine removal and liquid decolorization.

And it can be widely used in solvent ** and gas separation in the chemical industry.

Fruit shell activated carbon, coconut shell activated carbon, coal activated carbon.

The fundamental difference between the three types of activated carbon is the material.

As the most rational and desirable activated carbon in activated carbon, coconut shell activated inner carbon has a relatively high adsorption effect. The adsorption value is also high.

As a wood activated carbon, the adsorption effect of fruit shell activated carbon is inferior to that of coconut shell activated carbon, and it will be lower than that of coconut shell activated carbon.

Coal activated carbon is a commonly used activated carbon in daily life, with a good adsorption value and ideal. Its price-performance ratio is also very high.

The role of Shandong activated carbon, coconut shell activated carbon, coal activated carbon, and fruit shell activated carbon.

The difference between the material and the density of the time it takes to float on the water.

The coal carbon is large, the macropores are developed, and the ash content is large.

Coconut shell charcoal is small, the small holes are well developed, and the ash content is small.

Difference Material Density Hygroscopicity Ash Strength The same quality is placed in the same humidity environment, and the volume of wood charcoal is larger.

Coal-based charcoal

Wood charcoal husk charcoal has low strength.

Blackwater issues. Coal-based charcoal is relatively well developed (macromolecular structure can be removed) and belongs to a kind of husk carbon.

Coconut shell charcoal is expensive.

High strength, but methylene blue is lower than woody charcoal.

The adsorption capacity of macromolecules is weaker than that of coal-based carbon.

Activated carbon copy raw materials are different, and the effect is not the same

Generally, the effect of fruit shells and coconut shells is better. Activated du charcoal to zhi

After high-temperature activation, otherwise it is not activated carbon, this high-temperature process is different, the temperature is different, and the effect is not the same, so the activated carbon has a difference between good and bad. Coconut carbon is a new type of activated carbon containing photocatalyst and carbon fiber containing graphene and SOD cellulase, using imported coconut shell as raw material, after high-temperature activation and carbonization treatment. The adsorption capacity of coconut carbon for organic gases is 5 times that of ordinary activated carbon, and the adsorption rate is faster.

Coconut shell activated carbon is made of imported coconut shell carbonization material through efficient activation and refining, which has strong adsorption performance and super physical and chemical indicators! The appearance of coconut shell activated carbon is amorphous crushed carbon, non-toxic and tasteless, with large specific surface area, strong adsorption capacity, fast adsorption speed, low impurity content, and is widely used in high-purity gas, liquid phase adsorption, desulfurization, and completely remove formaldehyde and other toxic and harmful gases in homes, offices, hotels, public places, and automobiles. So, let me introduce to you the precautions for the use of coconut shell activated carbon and the use of coconut shell activated carbon.

Precautions for the use of coconut shell activated carbon.

1. During the transportation process, the coconut shell activated carbon should be prevented from mixing with hard substances, and should not be stepped on or stepped on to prevent the carbon particles from being broken and affecting the quality.

2. Storage should be stored in porous adsorbents, so in the process of transportation, storage and use, it is necessary to absolutely prevent water immersion, because after water immersion, a large amount of water fills the active void and makes it ineffective.

3. Coconut shell activated carbon prevents tar substances from being brought into the activated carbon bed during use, so as not to block the void of activated carbon and make it lose its adsorption effect. It is best to have decoking equipment to purify the gas.

4. When the fireproof activated carbon is stored or transported, prevent direct contact with the fire source, in order to prevent ignition, and avoid oxygen intake and regeneration thoroughly when the activated carbon is regenerated, and it must be cooled to below 80 with steam after regeneration, otherwise the temperature is high, and the activated carbon will spontaneously combust when exposed to oxygen.

Coconut shell activated carbon uses.

1. Demercaptan activated carbon: used as a carrier for gasoline demercaptan (deodorization) catalyst in the catalytic unit of the refinery.

2. Vinylon catalyst activated carbon: used as a catalyst carrier in the chemical industry, such as vinyl acetate catalyst carrier.

3. Activated carbon refined by monosodium glutamate: It is used for the decolorization and refining of mother liquor in the production process of monosodium glutamate, and can also be used for the decolorization and refining of fine chemical products.

4. Activated carbon for cigarette filters: used in cigarette filters in the cigarette industry to remove toxic and harmful substances such as tar and nicotine in cigarettes.

5. Special activated carbon for citric acid: used for decolorization, refining and deodorization of various acids such as citric acid, amino acids, cystine, etc.

6. Special activated carbon for direct drinking water treatment: activated carbon is used for deep water purification of household direct drinking water, water treatment of water plants, and bottled water production.

7. Special environmental protection activated carbon for anti-virus and chemical protection: filter grids and military gas masks filled with various ventilation equipment.
