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 ...

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 a...

  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 c...

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.
