The difference between wood, coconut and coal activated carbon

We live in a technology-driven society that is more health conscious than ever before. Whether it is for household applications, drinking water purification, gas purification, or other commercial applications, activated carbon seems to be almost ubiquitous. Tap water, for example, is full of impurities and is not considered drinkable. It also includes harmful chemicals, some of which are carcinogenic.

 

Activated carbon block filters are used to make tap water, and these filters use activated carbon, which is available in 3 different variants, as follows 

 

Wood-based activated carbon 

Coal based activated carbon

Coconut based activated carbon

 

Wood-based activated carbon has gained great popularity in the last few years and is recognized as a reliable choice, while coal-based activated carbon is the oldest known form of activated carbon. Coconut shell activated carbon is also popular and considered useful because it has a large surface area characterized by micro and mesopores.

 

Let's take a look at a head-to-head comparison between wood, coal, and coconut shell activated carbon types.

 

Differences between wood, coconut and coal activated carbon

 

activated carbon

 

1. Wood activated carbon 

 

This form of activated carbon is becoming popular year by year. Wood activated carbons are known for their excellent decolorization properties. They also have a unique porosity. Wood powder activated carbon is known for its non-toxic, large surface area and powerful adsorption capacity. 

 

It is made from selected wood types and sawdust. In addition to drinking water purification, wood-powdered activated carbon is used in many applications, including sugar, beverage and pharmaceutical production. The production of wood flour activated carbon can also be carried out by the phosphoric acid method. This method has several benefits, including fast filtration rates and the absence of zinc. This form of wood activated carbon is used in the food and pharmaceutical industries.

 

Wood activated carbon is well suited for steam activation and yield and is certainly worth mentioning when discussing wood activated carbon. This activated carbon has an ash content of almost 5% and has an excellent microporous structure.

 

Another popular type of wood activated carbon is bamboo charcoal. Bamboo charcoal is made from the moso bamboo plant and is used heavily in skin care products.

 

Yihang offers high grade powder and granular activated carbon. With the most advanced manufacturing facilities, we are equipped with high-end machines and experienced manufacturing experts.        

 

2. Coal Based Activated Carbon

 

Coal-based activated carbon is made from coal that has undergone a steam activation process. During the activation process, millions of pores are created on the surface of the carbon, which helps to increase the large surface area.

 

Bituminous coal is the most popular type of coal and is considered ideal due to its microporosity and 70% to 90% carbon content. Coal-based activated carbon is also used in other industrial applications such as sewage treatment and wastewater treatment. In addition to aquarium and pond water purification, it is also used for gas purification. If you are looking for a cost effective solution, then coal activated carbon is the one for you. It is also best suited for odor removal. 

 

3. Coconut Shell Activated Carbon

 

As the name implies, coconut activated carbon comes from coconut shells and also undergoes a steam activation process. In this process, millions of pores are created on the surface of the carbon. As a result, the total surface area of carbon increases. This form of activated carbon is used for drinking water purification and gas purification. It is known for its unique pore size distribution.

 

Coconut shell activated carbon is used for the treatment of acute poisoning and gastrointestinal problems. It is used in carbon filters to purify drinking water. In addition, it helps to remove organic matter. Coconut availability has never been a problem because coconuts grow year round and are harvested 3 to 4 times a year.

 

Conclusion of the differences between wood, coconut and coal activated carbon

 

Coconut, wood and coal-based activated carbons have unique properties and advantages of their own. The importance of these carbons cannot be underestimated for both domestic and commercial applications.

What is Activated Carbon

图片
Activated carbon is one of the most common adsorption media   used on filters to control indoor air quality and reduce pollutants. The popularity of activated carbon is due to its inherent ability to adsorb most organic chemicals due to the large surface area created by the increased activation on the carbon/charcoal surface. When it comes to the capture and control of gaseous compounds present in the indoor air space, activated carbon will quickly and effectively trap these contaminants on this activated filter media. In some cases, the charcoal/carbon material will be treated with additional chemicals during the activation of this material, which will be done through the use of a chemical called potassium permanganate. Potassium permanganate is used in activated carbon filter media to help attract reactions between the carbon media and the oxidation of polar or low molecular weight compounds. In addition, many manufacturers use this chemical additive on carbon filters to help extend

Waste Carbon Recovery for Environmental Sustainability

图片
Used granular (GAC) or extruded (EAC) activated carbon can be recycled through thermal activation, which involves treating the used carbon in a high temperature activation oven at 850°C or above. Recovery by thermal regeneration is only one of the steps in the complete service package. The recovery process consists of two main processes: 1) reactivation process and 2) tail gas treatment and energy recovery process.     The reactivation process itself can be subdivided into four steps. 1) Drying of used carbon The used carbon is fed into the furnace and heated from ambient temperature to 105 - 110°C. Water and some low boiling compounds are evaporated and released into the furnace atmosphere. As long as there is water in the pores,  the temperature of the carbon  remains between 105 and 110°C. 2) Desorption of low boiling point organics. As the carbon dries, the temperature increases further to about 450°C. During this temperature increase, various organic compounds are desorbed from th
