Your backyard barbecue is probably the first thing that comes to mind when you hear the word charcoal, but activated charcoal is actually quite different from what you use to cook your steak on a hot summer day. Considered a natural remedy for many ailments, activated charcoal is a great alternative to drugs or products that contain a lot of artificial ingredients. It can be made from a variety of sources, but activated charcoal,  usually from coconut shells , is ideal. When the material used to make it is heated to very high temperatures, its composition changes and is similar to charcoal, except that it is much more porous. Many people believe that activated charcoal is like a sponge that absorbs everything the body comes in contact with. After all, it is used when someone ingests a poison, so it makes sense. However, activated charcoal is more subtle in that it uses a negative charge to attract toxins. This process is called adsorption and is quite different from the process we all

Used granular (GAC) or extruded (EAC) activated carbon can be recycled through thermal activation, which involves treating the used carbon in a high temperature activation oven at 850°C or above. Recovery by thermal regeneration is only one of the steps in the complete service package. The recovery process consists of two main processes: 1) reactivation process and 2) tail gas treatment and energy recovery process.     The reactivation process itself can be subdivided into four steps. 1) Drying of used carbon The used carbon is fed into the furnace and heated from ambient temperature to 105 - 110°C. Water and some low boiling compounds are evaporated and released into the furnace atmosphere. As long as there is water in the pores,  the temperature of the carbon  remains between 105 and 110°C. 2) Desorption of low boiling point organics. As the carbon dries, the temperature increases further to about 450°C. During this temperature increase, various organic compounds are desorbed from th

  WHY IS PELLETIZED ACTIVATED CARBON A POWERFUL VOC & HYDROGEN SULFIDE REMOVAL PRODUCT? Activated carbon is a highly porous material, allowing for the rapid adsorption of VOCs and hydrogen sulfide. A large internal surface area enables activated carbon to capture pollutants, further enhanced through chemical impregnation. Learn more about  activated carbon technology  in this article. Activated carbon pellets are the ideal method for capturing pollutants from air streams. However, the best pelletized activated carbon product is entirely dependent on your application. Carbonxt manufactures pellets ranging from 3-mm to 9-mm sizing.   SOURCING THE BEST ACTIVATED CARBON PELLETS Finding an efficient pellitized activated carbon solution is critical to meeting compliance and controlling costs. At  Yihang , our activated carbon pellets are high performing and cost effective. Our R&D team works to design an easy to implement solution, and will engineer the custom product that will best

ACTIVATED CARBON PELLETS: AN EFFECTIVE VOC & HYDROGEN SULFIDE REMOVAL SOLUTION VOCs and Hydrogen Sulfide are toxins that are critical to remove from gas streams, but solutions can be costly to plants. Finding an effective product is key to controlling costs and maintaining safe emissions standards.   What is Hydrogen Sulfide? Hydrogen sulfide is a colorless, poisonous gas that smells that rotten eggs and is naturally produced, but can also be created or used in industrial processes, such as petroleum production and refinement, wastewater treatment, textile manufacturing, and more. It’s critical to remove hydrogen sulfide from gas streams because exposure causes symptoms ranging in severity from fatigue to death.     What are VOCs? There are over 10,000 kinds of VOCs, or volatile organic compounds. Different types of VOCs are emitted from different industrial sources, including landfill sites, manufacturing operations, and chemical processing facilities.

Activated carbon has over 2,500 commercial product applications. Most wastewater treatment plants use carbon to purify the water and air leaving the facility. But you won't find their characteristics and properties in a "formal" education. You learn about them on the job. Activated carbon is an inert solid adsorbent material  commonly used to remove a variety of dissolved contaminants from water and process gas phase streams. It is made from virtually all carbon-containing raw materials, including coconut shells and members of the coal family, as many readers already know. Adsorption is the accumulation of a gas or liquid on the surface of a liquid or solid substrate, as opposed to absorption, in which an invasive substance enters the volume or volume of the substrate. Activated carbon is porous, inexpensive and easy to use as an adsorbent, providing a large surface area to remove contaminants. It has a greater useful surface area per gram than any other material availabl

Granular Activated Carbons are a very versatile group of adsorbents, with capability for selectively adsorbing thousands of organic, and certain in- organic, materials. From medicinal uses of powdered carbons in ancient Egypt, through charred interiors of whiskey barrels, carbon has been activated and used as an adsorbent for centuries. Granular vapor phase activated carbon  media was first widely used in WWI military gas masks and, in the years between World Wars, commercially in solvent recovery systems. Granular liquid phase activated carbons achieved their first prominent applications following WWI’, in sugar de-colorization and in purification of antibiotics. Today, there are hundreds of applications — if diverse uses under the general heading of environmental control are counted separately, ongoing applications number in the thousands Adsorption/Adsorbents/Granular Activated Carbon Since adsorption is a comparatively specialized technology, a capsule definition of terms may be he

Activated charcoal can be made from a variety of carbon-rich materials such as wood, coal, bone, coconut shells, nut shells, peat and agricultural residues. The pore properties and adsorption capacity of activated carbon depend on the type of raw material used for its production. It also depends on the method used for its activation. Black bone charcoal is the one with the lowest adsorption capacity, while gray-brown bone charcoal is the best. White carbon exhibits a low capacity for fluoride removal. The surface area of these bone carbons is usually lower than that of activated carbon. However, they have high adsorption of certain metals such as copper, zinc and cadmium. Activated carbon produced from nut shells and coconut shells  has the best adsorption capacity and the largest surface area. Even if you use hardwood, the procedure is the same, but using coconut shells produces a high quality activated carbon. ▴ Coconut shells (without meat) ▴ Burn sinks, drums or slender iron contai
