Including coal and coconut shell activated carbon manufacturing has become the most commonly used raw Youdou. The manufacture of activated carbon is basically divided into two processes, the first process including dehydration and carbonization, the raw material is heated at a temperature of 170 至 600 ℃ drying, the original organic matter about 80% charring. The second process is to make the charcoal activated, which is through the use of activators such as water vapor and carbon to complete the reaction, the endothermic reaction is mainly in the mixed gas consisting of CO and H2, for burning charcoals heated to a suitable temperature (800 to 1000 ℃), to burn them all biodegradable material, the resulting well-developed porous structure and huge specific surface area, which has a strong adsorption capacity. Activated carbon pore by pore size can be divided into three categories. Macroporous: Radius 1000 - 1000000 A. Transition pore: Radius 20 - 1000 A. Micro Hole: Radius - 20 A. Activated carbon made from different materials have different pore sizes. From coconut shell activated carbon having a minimum pore radius. Wood activated carbon typically has a maximum pore radius, larger molecules are used for adsorption, and almost exclusively in the liquid phase. The first type of granular activated carbon for water treatment in the city that is used in the field made of wood, called charcoal. Coal activated carbon pore size in between. In the activated carbon from coal, lignite activated carbon activated carbon has more than anthracite transition pore and larger average pore size, it can effectively remove organic molecules in water. Typically activated carbon used in water treatment, the surface area may not be too large, but should have a higher transition pores and larger average pore size. Japanese Market Complex Sale
