What Is Pelletized Activated Carbon

Definición

Carbón activado granulado is a special cleaning tool. Experts say activated carbon can come from wood, coconut shells, or coal. There are two main ways to make it. Chemical activation uses chemicals to make tiny holes. Physical activation uses steam or heat instead of chemicals. This way takes more time and energy. Pelletized Activated Carbon is good at trapping gases and chemicals. Some companies add copper to help separate gases like carbon monoxide. Steam activation helps the pellets clean air and water better.

Pellet Form

Pelletized Activated Carbon looks like small cylinders. These pellets have smooth outsides and different sizes. Most pellets are between 0.8 mm and 5.0 mm wide. Factories use standard sizes, but custom sizes are also made. Here is a table that shows the usual shapes and sizes:

The pellet shape makes it easy to use in filters. The pellets fit close together, so air and water move through them well.

Coal-Based Origin

Most Pelletized Activated Carbon is made from coal. Coal is chosen because it makes strong pellets that last longer. Here are the main types of coal used:

• Antracita: This coal makes strong pellets with little ash. It gives high bulk density and great gas adsorption.

• Bituminous Coal: This coal makes pellets with medium and big pores. It helps remove color and has more ash.

Coal-based pellets are good for cleaning air and water. They are used for hard jobs in factories and treatment plants.

Production

Extrusion

To make Pelletized Activated Carbon, coal powder is mixed with a binder and a solvent. The mixture must be smooth so all pellets work the same. Factories use extrusion to shape the mixture into hard pellets. Most pellets are between 0.8 mm and 5 mm wide. Some factories make bigger pellets, up to 6 mm, for special jobs.

Here is how extrusion works:

1. Mix coal powder, binder, and solvent until smooth.

2. Push the mixture through a machine to make pellets.

3. Dry the pellets to get rid of extra solvent. Drying can take hours or days.

4. Sometimes, heat the dried pellets to make them stronger.

Tip: Pellet size changes how air or water moves. Small pellets catch more particles. Big pellets let air or water move faster.

Activación

After extrusion, pellets need activation. Activation gives pellets their cleaning power. There are two main ways to do this:

• Physical Activation: Pellets are treated with steam or carbon dioxide at high heat. This makes tiny holes inside each pellet. The holes help trap gases and chemicals. Physical activation gives a high surface area, but some material may be lost.

• Activación química: Pellets are soaked in chemicals like zinc chloride or potassium hydroxide. This uses lower heat and gives more finished pellets. But it can make waste that needs careful handling.

Both ways make pellets that clean air and water well. The method you choose depends on your needs and how you use the pellets.

Control de calidad

Factories want every batch of pellets to work the same. They use strict quality control steps to check this. Pellets are tested for size, strength, and how well they trap chemicals. Raw materials are watched closely to keep the product the same.

Note: Good quality control helps pellets last longer and work better in filters.

Pelletized Activated Carbon Properties

Surface Area

When you look at Carbón activado granulado, you notice that the pellets have a huge surface area. This means each pellet has many tiny holes and spaces inside. These holes help the pellets trap gases, chemicals, and odors. You can think of the surface area like a sponge. The more holes a sponge has, the more water it can soak up. In the same way, the more surface area the pellets have, the more they can clean.

Scientists measure surface area using a special test called the BET method. Most pellets have a surface area between 800 and 1200 square meters per gram. That is about the size of three tennis courts packed into one tiny pellet! When you use pellets with a high surface area, you get better cleaning power for air and water.

Tip: If you want to clean tough chemicals or strong smells, choose pellets with a higher surface area.

Hardness

Hardness tells you how strong and tough the pellets are. You want pellets that do not break or turn into dust when you use them. Factories test hardness by putting a set amount of pellets into a rotating device. They tumble the pellets, then use ball milling and sieving to see how much mass remains. This test shows how well the pellets hold up during use.

Here is how hardness is measured and what you should look for:

• Workers load pellets into a rotating drum.

• The drum spins and tumbles the pellets.

• After tumbling, workers use ball milling and sieving to check the mass before and after.

• Good pellets keep most of their mass and do not break easily.

Most industrial pellets have a hardness value greater than 88%. This means they stay strong in filters and do not create dust. You also see another number called the iodine value. This number tells you how well the pellets trap chemicals. For good pellets, the iodine value should be above 1100 mg/g. If you choose pellets with high hardness and a good iodine value, you get a product that lasts longer and works better.

Low Ash Content

Ash is the leftover material after you burn the pellets. You want pellets with low ash content because ash does not help with cleaning. High ash can block the tiny holes and lower the surface area. When you use pellets with low ash, you get better performance and less waste.

Factories make sure the pellets have low ash by choosing the right coal and using careful production steps. You can check the ash content on the product label. Most good pellets have less than 10% ash. If you use pellets with low ash, your filters work better and last longer.

Note: Low ash content helps keep your system clean and reduces the need for maintenance.

Particle Size

The size of each pellet is very important. It changes how well your filter works. Activated carbon comes in different sizes. Each size has its own good points and uses.

Powdered activated carbon (PAC) has very small particles. These are less than 0.18 mm wide. PAC works quickly because it has lots of surface area. People use PAC for cleaning water, air, and chemicals. PAC removes bad stuff fast, but you need to change it often. PAC can be hard to handle in big systems. It makes dust and can block machines.

Granular activated carbon (GAC) has bigger particles. These are between 0.2 mm and 5 mm wide. GAC gives a good mix of cleaning and flow speed. You use GAC in water filters, air cleaners, and factory machines. GAC lasts longer than PAC. You can clean and use GAC again. GAC cleans a bit slower than PAC. But it is easier to use in big filters.

Extruded activated carbon (EAC) has even bigger particles. These are usually 1 mm or more. Pelletized forms are part of EAC. EAC is used for cleaning gases, saving solvents, and air systems. EAC pellets are strong and make little dust. This is good for places that need clean air and tough pellets. EAC has less surface area than PAC and GAC. But EAC pellets last longer and keep their shape.

Tip: Use PAC if you want fast cleaning. Pick EAC or pelletized activated carbon for strong pellets in high-flow systems.

Here is a table to help you compare:

Always pick the right size for your system. Small particles catch more bad stuff but slow down flow. Big pellets let air and water move faster but may clean less per gram. You get the best results when you balance cleaning, flow, and strength.

Note: Always look at the particle size on the label before buying. The right size helps your filter work better and last longer.

Beneficios

High Adsorption

You want a cleaning material that grabs bad stuff. Pelletized Activated Carbon does this job very well. The pellets have lots of tiny holes inside. These holes are called micropores. Micropores trap gases, chemicals, and heavy metals. When air or water goes through the pellets, the bad things get stuck.

The way the pellets are built is important. Micropores are the main spots for trapping. Mesopores help move the bad stuff deeper inside. This mix helps the pellets work fast and well.

Here is a table that shows how Pelletized Activated Carbon removes common contaminants:

If you need to clean air or water with tough chemicals, these pellets work great. You get cleaner air and water. This helps keep you healthy and protects nature.

Tip: Pick pellets with more micropores for better cleaning. This helps you fight strong smells and dangerous chemicals.
