Charcoal Active Carbon Production Working Process

      As we all know, existing know life entity is based on carbon basis. Every circle in like is inseparable from carbon based materials, ranging from diamond ring, mobile phone to space shuttle and space spacecraft. These items are composed of various carbon basis materials. Carbon and active carbon mainly talked in this article are two important carbon based materials.
      Carbon mainly refers to charcoal and coal whose major function is to be used as solid fuel and produce heat for production and life. Charcoal comes from tree branch, wood chips, wood sawdust, rice husk, coconut shell, palm shell and kernel of fruits and nuts. Coal comes from plants after hundreds of years’ transformation. Former one is artificial carbon and latter one is naturally formed carbon. What they have in common is that their carbon atom is arranged out of order. Their fixed carbon accounts for less than 100% of solid matters and there is no holes between carbon atoms.
      The easiest way to produce charcoal is increasing temperature under anaerobic condition. Wood materials will transform into charcoal under 300 to 450 degrees. Therefore, you can use both direct burning and indirect burning way to get charcoal. There will be crisp sound if you knock on good quality charcoal. There are many types of common charcoal carbonization equipment, like vertical hoisting furnace, continuous carbonization furnace and soil furnace.
You can get another important absorptive materials-active carbon after further processing steps for charcoal and make it with more small holes. Active carbon can be used to absorb hazardous gas in environment and impurities existing in liquid environment. Water purification machines used at home always adopt active carbon as filtering texture. Raw materials for active carbon can be both wood base charcoal and coal base charcoal. Besides carbonization process, activation procedure is necessary to make active carbon. Commonly used method are chemical method and physical method. Physical method always adopt vapor for activation. Its principle is to pass into vapor in 950 degrees or higher environment so that holes grow in charcoal and produce active carbon with many holes.
      Active carbon makes great contributes to our life and its consumption quantity is also very huge. Theoretically, used active carbon belongs to hazardous wastes should be dealt with by qualified treatment plants. Regeneration method is a key way for recycling and reutilization of used active carbon. Demands for used active carbon regeneration grows fast and fast in water purification, waste gas purification, decolorized active carbon, gold mines and waste water treatment plants. Working principle for activation and regeneration is similar. What is different is that exhaust gas must be deeply analyzed and dealt for regeneration process. For example, exhaust gas must enter to secondary combustion chamber for high temperature disposal in order to prevent environment pollution.
