Reagglomerated Activated Carbon VS GAC Granular Activated Carbon
What is Agglomerated Activated Carbon?
What is an agglomerated material? Different from granular activated carbon, reagglomerated activated carbon uses clean coal from different regions as raw materials to make a proportion, and reagglomerates the powdered coal into particles.
The produced briquette activated carbon has a reasonable pore structure distribution, well-developed micro- and mesopores, high mechanical strength, and is renewable. It has the characteristics of low ash, high iodine value, high molasses value, high methylene blue and no floating matter.
Heycarbons could select clean coal from different provinces and make proportions to produce different types of products according to different application requirements.
Reagglomerated Activated Carbon VS GAC Production Process
Agglomerated Activated Carbon
Heycarbons selects different types of clean coal from different regions for making a proportion. The powdered coal is pressed into blocks by machine. After carbonization and activation, the activated carbon is crushed and screened into suitable particle sizes according to customer needs. The video below details the production process of heycarbons reagglomerated activated carbon.
GAC Granular Activated Carbon
The larger coal particles are processed in the carbonization furnace and then activated. During the activation process, technicians control the different heights and sections of the activation furnace at different temperatures. The activated carbon is cooled naturally in the storage bin. Finally, it is crushed, screened and packaged. The video below details the production process of heycarbons granular activated carbon.
Comparison
The biggest difference between reagglomerated activated carbon and granular activated carbon is that reagglomerated activated carbon is made by reagglomerated coal powder into blocks, while GAC is made by breaking large blocks into small pieces.
Direct Activation of granular activated carbon production process : the single coal is turned into granular activated carbon after crushing, baking, activation and screening.
Reagglomeration of briquette activated carbon production process : the coal blend is turned into reagglomerated activated carbon after pulverizing, agglomeration, crushing, baking, activation and screening.
Reagglomerated Activated Carbon VS GAC Physical Properties
The video shows in detail the difference between reagglomerated activated carbon and granular activated carbon.
Brightness
Due to the different production methods, GAC granular activated carbon is brighter than heavy agglomerated activated carbon.
Granularity
Reagglomerated activated carbon: Due to its unique agglomeration structure, the particle size is more uniform, usually has better mechanical strength and fluidity, and is suitable for the adsorption of high-flow gas and liquid.
Granular activated carbon: The particle size is larger, suitable for adsorption applications that require a larger surface area. Irregular shape, the stacking effect during filling may lead to low porosity, affecting the fluidity of the fluid.
Specific Surface Area
Reagglomerated activated carbon: Compared to granular activated carbon, agglomerated activated carbon has fewer micropores and more mesopores or macropores, which gives it a lower specific surface area. It is usually between 400 m²/g and 800 m²/g.
Granular activated carbon has a relatively large particle size, but due to their complex internal structure, there are a large number of micropores and mesopores, resulting in a large specific surface area. The specific surface area of granular activated carbon is usually between 500 m²/g and 1200 m²/g, depending on the raw materials, activation method and customer requirements. The high specific surface area provides good adsorption performance and high activated carbon adsorber ability.
Mechanical Strength
Reagglomerated activated carbon is made by agglomerating smaller activated carbon particles with a binder. This agglomerated structure gives it a higher overall mechanical strength. The agglomerated activated carbon particles are stronger and less likely to break. The bonding force between particles is stronger, reducing the risk of pulverization. The new extrusion process launched by heycarbons in 2019 ensures excellent mechanical strength and guarantees negligible losses after multiple reactivations.
Granular activated carbon is usually composed of porous carbon particles with a large number of micropores and mesopores on its surface. Although these pore structures provide good adsorption performance, the mechanical strength of granular activated carbon is weak. In high-velocity airflow or liquid, granular activated carbon is easily worn, resulting in breakage and pulverization. This will lead to a decrease in adsorption effect during application, and even require frequent replacement of activated carbon.
Adjustment of Parameters
Reagglomerated activated carbon has more advantages in parameter adjustment. Due to coal blending technology, reagglomerated activated carbon can adjust parameters more flexibly. And it can achieve high methylene blue and molasses value.
Heycarb Reagglomerated Activated Carbon VS GAC Products Introduction
Heycarbons HEYRGAC Reagglomerated Activated Carbon
Heycarbons HEYRGAC is a granular activated carbon with low acid soluble iron content, designed for the purification and decolorization of aqueous and organic liquids. It can be effectively used in fixed or moving beds. The particle size selected is 12 x 40 mesh, which allows high adsorption rates and low flow resistance, suitable for liquids of medium viscosity.
HEYRGAC contains virtually no fines or dust. HEYRGAC is made from selected grades of bituminous coal combined with a suitable binder, which gives it excellent hardness and long life. Produced by high temperature steam activation under strictly controlled conditions, this carbon has a high surface area, large pore volume, high density and pore structure, making it ideal for the adsorption of color bodies and odor molecules from solution.
