Ecogreen Cleantech is a leading manufacturer of Virgin Pelletized Vapor Phase Activated Carbon used for odour control, smoke removal and in air purifiers.
Virgin vapor phase pelletized activated carbon (VVPAC) is a type of activated carbon that is made from virgin (i.e. non-recycled) materials and is in the form of pellets or beads. It is typically used in air and water purification systems, as well as in other applications where adsorption of impurities is needed. VVPAC is known for its high adsorption capacity and low pressure drop, making it an efficient and cost-effective option for many applications.
How are Virgin vapor phase pelletized activated carbon manufactured?
VVPAC is typically manufactured using one of two methods: physical activation or chemical activation.
Physical activation involves heating the raw material, typically coconut shell or wood, in the absence of air at high temperatures (around 800-1000°C) with steam. This causes the internal structure of the material to change, creating a highly porous structure with a large surface area.
Chemical activation involves treating the raw material with chemicals, such as phosphoric acid or zinc chloride, which causes the internal structure of the material to change and creates a highly porous structure.
After activation, the material is formed into pellets or beads, and then subjected to steam activation process to remove any remaining impurities and to improve the physical properties of the carbon. The final product is a virgin vapor phase pelletized activated carbon that is highly porous and has a large surface area, making it an efficient adsorbent.
What are the uses of Virgin Vapor Phase Pelletized Activated Carbon?
Virgin vapor phase pelletized activated carbon (VVPAC) has a wide range of uses due to its high adsorption capacity and large surface area. Some of the most common uses include:
- Air purification: VVPAC is used in air purification systems to remove impurities such as volatile organic compounds (VOCs), odors, and other pollutants.
- Water purification: VVPAC is used in water filtration systems to remove impurities such as chlorine, chloramines, and other dissolved contaminants.

How can virgin Vapor Phase Pelletized Activated Carbon help in air purification?
Virgin vapor phase pelletized activated carbon (VVPAC) can be used in air purification systems to remove impurities such as volatile organic compounds (VOCs), odors, and other pollutants. It works by a process called adsorption.
When air passes through a bed of VVPAC, the VOCs and other impurities adhere to the surface of the carbon pellets.
This is due to the high surface area and porous structure of the VVPAC, which provides a large number of sites for the impurities to stick to.
Adsorption is a physical process, not a chemical one, and the impurities are not chemically altered, but simply trapped by the carbon surface. Once the VVPAC reaches its adsorption capacity it will need to be replaced or regenerated.
VVPAC has a high adsorption capacity and a low pressure drop, which makes it an efficient and cost-effective option for air purification systems. It can be used in a variety of settings, including homes, offices, industrial facilities, and vehicles.
VVPAC can also be used in combination with other air purification technologies, such as HEPA filters, to provide a multi-stage filtration process that can remove a wide range of impurities from the air.
In addition to VOCs, VVPAC can also effectively remove other impurities from the air, such as odors and smoke. It is particularly effective at removing impurities that are in low concentrations, as the high surface area of the carbon pellets allows for a large amount of adsorption in a small amount of carbon.
VVPAC can be used in a variety of air purification systems, including stand-alone air purifiers, air filtration systems for HVAC systems, and portable air purifiers. It can be used in residential, commercial, and industrial settings.
One of the key advantages of using VVPAC in air purification systems is that it is a passive technology, meaning it does not require any power or energy to operate. This can save energy costs and make the system more reliable.
It is also relatively low maintenance, and can be regenerated or replaced when it reaches its adsorption capacity, which can prolong the life of the air purification system.
Overall, VVPAC is a highly effective, efficient and cost-effective option for air purification systems. Its high adsorption capacity, low pressure drop, and long service life make it an ideal choice for a wide range of settings and applications.
What is the meaning of “vapor phase” in virgin Vapor Phase Pelletized Activated Carbon?
The term “vapor phase” in virgin vapor phase pelletized activated carbon (VVPAC) refers to the state of the impurities that are being removed by the carbon. In this case, it means that the impurities are in a gaseous state, as opposed to a liquid or solid state.
Activated carbon is particularly effective at removing impurities in the vapor phase, as the large surface area and porous structure of the carbon provides a large number of sites for the impurities to stick to. The high surface area of the VVPAC allows it to adsorb a large amount of impurities in a small amount of carbon, making it an efficient and cost-effective option.
It is important to note that VVPAC can also adsorb impurities in liquid or solid state as well, but its high efficiency in vapor phase adsorption is what makes it different from other types of activated carbon.
VVPAC is particularly useful for air purification, as it can effectively remove volatile organic compounds (VOCs) and other gaseous impurities from the air. It can also be used in other applications where the impurities are in a gaseous state, such as gas separation or solvent recovery.
As the vapor phase impurities are in gaseous state, it makes it easier for them to diffuse and penetrate into the porous structure of the carbon and adsorb to the surface of the VVPAC. The adsorption process is also relatively fast for vapor phase impurities compared to liquid or solid impurities, as the molecules are not bounded by surface tension or viscosity.
Additionally, the VVPAC pellets have a consistent particle size and shape, which means that the air can flow evenly through the carbon bed. This ensures that all impurities have an equal chance of adsorbing to the carbon, leading to a higher overall efficiency of the carbon.
It is also worth noting that VVPAC can be regenerated by heating it to a high temperature in the presence of steam, which will remove the impurities that have adsorbed to the carbon. This process is known as “regeneration” and allows
VVPAC to be reused multiple times, making it a cost-effective option in the long run.
Overall, the “vapor phase” in virgin vapor phase pelletized activated carbon refers to the gaseous state of the impurities that the carbon is designed to remove. Its high adsorption capacity, low pressure drop, and ability to be regenerated make VVPAC a highly efficient and cost-effective option for air purification and other applications where impurities are in the vapor phase.
