What Is Beverage Activated Carbon
Properties and Structure
You use Beverage Activated Carbon to clean drinks because it has unique physical and chemical properties. This material contains a network of pores that gives it a large surface area. You can see how these properties help in the table below:
Property | Description |
|---|---|
Porosity | High porosity with a vast network of pores (micropores, mesopores, macropores) providing a large surface area (800 to 1500 m²/g) for effective adsorption of various substances. |
Particle Size and Shape | Varies from fine powders to larger granules; fine powders have faster adsorption kinetics, while granules are easier to handle and separate. |
Density | Apparent density ranges from 0.4 to 0.6 g/cm³, affecting packing density and handling; lower density may indicate higher porosity. |
Hardness and Abrasion Resistance | Sufficient hardness and abrasion resistance are necessary to maintain integrity during mechanical stress in high-flow systems, preventing clogging and contamination. |
You also benefit from its surface chemistry. Beverage Activated Carbon contains groups like hydroxyl, carboxyl, and phenolic. These groups interact with substances in drinks, helping to remove unwanted compounds while keeping good flavors.
How Adsorption Works
Adsorption is the main process that makes Beverage Activated Carbon effective. You can think of adsorption like Velcro. When you pour a beverage through activated carbon, impurities stick to its surface just like small objects stick to Velcro. The high internal surface area, around 1,000 m² per gram, gives many places for molecules to attach. The pore volume ranges from 0.3 to 3 mL per gram, which increases its capacity to trap contaminants. Micropores, smaller than 2 nm, have the highest adsorption energy and work best for small molecules. Mesopores, between 2-50 nm, help remove larger organic contaminants. Macropores, above 50 nm, let molecules move into the smaller pores.
Tip: The more surface area and pores activated carbon has, the more impurities it can remove from your drink.
Granular Form and Micro-Pores
You often use Beverage Activated Carbon in granular form. Granules last longer and allow for continuous filtration. This form helps you remove unwanted color, taste, and odor. It also eliminates trace organic contaminants and ensures uniform taste and appearance across batches. The micro-pore structure is important for purification. You can see the pore types and their functions in the table below:
Pore Type | Diameter Range | Functionality |
|---|---|---|
Macropores | Above 50 nm | Facilitate the flow of larger molecules |
Mesopores | 2-50 nm | Enhance adsorption of medium-sized molecules |
Micropores | Below 2 nm | Provide high surface area for adsorption of small molecules |
You get a cleaner beverage with improved taste and clarity when you use granular activated carbon.
