What Is Pelletized Activated Carbon

Definition and Pellet Shape
Pelletized activated carbon is a strong cleaning tool. Experts say it is an extruded, cylindrical adsorbent. Each pellet looks like a tiny cylinder. This shape makes the pellets tough and hard to break. Air and gas can move through the pellets easily. This helps them work well for gas-phase filtration. They also support catalysts.
Pelletized activated carbon comes in many sizes. The size changes how well it works for different jobs. Here is a table that shows common sizes and what they do best:
Size Type | Size Range | Application Impact |
|---|---|---|
Mesh Size | 8×30 Mesh | Balances flow rates and surface area for water treatment. |
Pellet Size | 2mm | High mechanical strength and good adsorption for air filtration and industrial use. |
Smaller Mesh | 12×40, 16×50 Mesh | Ideal for high surface area needs in water purification and pharmaceuticals. |
Larger Pellets | 3mm, 4mm | Higher flow rates with mechanical strength, less prone to clogging. |
Tip: Pick larger pellets for cleaning air or gas. Use smaller mesh sizes for water or medicine uses.
How It’s Made
Extrusion and Compression Process
Making pelletized activated carbon takes several steps. First, raw materials like coal, wood, or coconut shells are used. These are mixed with binders to make a paste. The paste is pushed through a mold to form pellets. Then, the pellets are dried.
Next, the pellets are heated with little oxygen. This step is called carbonization. It removes unwanted chemicals. After that, the pellets are activated. High heat opens tiny pores inside each pellet. These pores help trap and hold dirt and chemicals.
Here is a simple list of the main steps:
Mix raw materials and binders to make a paste.
Push or mold the paste into pellets and dry them.
Heat the pellets with little oxygen to carbonize them.
Activate the pellets with high heat to make pores.
Common Raw Materials (e.g., Bituminous Coal)
Pelletized activated carbon can be made from different things. Each material has its own good points. Here is a table that shows the most common ones and their strengths:
Raw Material | Advantages |
|---|---|
Wood | Easily obtainable, good for various applications |
Coconut Shells | High surface area, effective for adsorption |
Coal | Cost-effective, widely available |
Coconut shells give a high surface area for better cleaning.
Coal costs less and is easy to get almost anywhere.
Pelletized vs. Other Forms
You may wonder how pelletized activated carbon is different from other types. The main types are granular, powdered, and pelletized. Each one has special features and uses.
Property | Granular Activated Carbon (GAC) | Powdered Activated Carbon (PAC) |
|---|---|---|
Particle Size | 0.2 to 5 mm | Less than 0.188 mm |
Surface Area | Smaller | Larger |
Form | Solid | Powder |
Common Applications | Continuous processes | Batch processes |
Pelletized activated carbon is special because it has the same shape and size. It is easier to use and makes less dust than powdered types. The pellets do not break easily, so they last longer in filters. If you need a strong filter for air or gas, pelletized activated carbon is a great choice.
How It Works
Adsorption Process
Pelletized activated carbon cleans air and water by adsorption. Adsorption means the pellets grab and hold chemicals. This grabbing happens on the outside of each pellet.
Surface Area and Porosity
Each pellet has lots of tiny holes called pores. These pores make a big surface area inside the pellet. More surface area means more room for pollutants to stick. Here is why adsorption works well:
The pellets have small pores that make more surface area.
Pollutants stick to the surface because of special forces.
The kind of pollutant and the carbon’s features change how well it works.
This lets you take out many kinds of bad stuff from air or water.
Contaminant Removal Mechanism
Pelletized activated carbon can catch tough pollutants. The pellets trap these things so they do not get through the filter. The table shows which pollutants are removed best:
Contaminant Type | Effectiveness of Removal |
|---|---|
Volatile Organic Compounds (VOCs) | High |
Mercury | High |
You can see pelletized activated carbon is great for removing VOCs and mercury. These are found a lot in factories and water systems.
Why Pellet Shape Matters
The shape of the pellets helps the filter work better. You get many good things from the round or cylinder shape:
Pellets move easily and do not stick together.
The filter works evenly because the pellets do not separate.
Bigger pellets let air or water move through easily.
Large pellets give more time for cleaning.
Small mesh can slow flow and raise pressure, but bigger pellets stop this.
You also get easier handling and less channeling in filters. Channeling is when air or water skips most of the filter. Pelletized activated carbon helps stop this. The table compares pelletized aggregates to regular ones:
Metric | Pelletized Aggregates | Conventional Flocculated Aggregates |
|---|---|---|
Solid Flux | 13 times higher | Lower than pelletized |
Required Filtration Area | 16% less | More than pelletized |
Filtration Time | 18% shorter | Longer than pelletized |
You can see pelletized activated carbon filters faster and uses less space. This makes it a smart pick for many cleaning jobs.
Pelletized Activated Carbon Features
Uniform Size and Shape
Pelletized activated carbon is shaped like small cylinders. The pellets are all about the same size, from 1.5 to 9 mm wide. This even size helps filters work better. When pellets are the same size, air or gas cannot find shortcuts through the filter. This stops channeling, which means the filter cleans everything well. If the pellets only change by 0.3 mm in length, there are 23% fewer pressure problems. This is very helpful in tall towers, where the filter is much taller than it is wide. Using uniform pellets gives you smooth flow and better cleaning.
Tip: Using pellets that are all the same size makes your filter work better and easier to take care of.
High Surface Area
Pelletized activated carbon has a lot of surface area. Each pellet has thousands of tiny holes called pores. These pores make the surface area very large, up to 3000 square meters for each gram. More surface area means more places for pollutants to stick. This helps the filter catch more bad stuff. It works well for cleaning water and for special uses like supercapacitors. High surface area also helps take out heavy metals from water, so the water is cleaner.
Here is a table that shows how pelletized activated carbon compares to other types:
Characteristics | Granular Activated Carbon | Pellet Activated Carbon | Powdered Activated Carbon |
|---|---|---|---|
Particle Size | 0.2~5 mm | Diameter 1~5 mm | <0.18 mm |
Shape Features | Irregular granules | Regular cylindrical | Fine powder |
Adsorption Performance | Moderate speed | Ideal for gas adsorption, especially VOCs | Fastest adsorption rate |
Mechanical Strength | High | Highest | Low |
Regeneration Ability | Multiple regenerations | Multiple regenerations | Usually not regenerated |
Main Applications | Water treatment, air filtration, food industry | Air purification, gas treatment | Emergency treatment, food processing |
Low Dust and High Hardness
You want your filter to last and stay clean. Pelletized activated carbon makes little dust and is very hard. The pellets have a hardness of about 92%. This is higher than most other types. Less dust means your filter will not get blocked as fast. You will not need to clean it as often. Hard pellets do not break easily, so you lose less carbon.
These pellets are made from virgin coal and clean well.
Low dust and high hardness help stop clogging and keep the filter working longer.
Strong pellets mean you do not have to change the filter as much.
