Where to sell shell activated carbon? Price and quality are how kind? North Branch Green Clean Carbon brands. Various shell activated carbon, charcoal gold, desulfurization charcoal. Sales Department: North Branch Zhu Xiang activated carbon-containing material can be made of many kinds of these materials, including wood, sawdust, coal, coke, peat, lignin, stone, hard shell, sugar pulp, bone, lignite, petroleum residues, and so on. Including coal and coconut shell activated carbon manufacturing has become the most commonly used raw Dou. The manufacture of activated carbon is basically divided into two processes, the first process including dehydration and carbonization, the raw material heated at 170 to 600 ℃ drying temperature, and to about 80% of the original organic matter charring. The second process is the activation of carbonized material, it is through the use of activators such as water vapor and carbon react to completion, and in the endothermic reaction is mainly composed of CO and H2 gas mixture for burning charcoals heated to the appropriate temperature (800 to 1000 ℃), in order 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. Big hole: Radius 1000 - 1000000 A. Transition pore: Radius 20 - 1000 A. Microporous: Radius - 20 A. Activated carbon made from different materials having different pore sizes. From the coconut shell activated carbon has a minimum pore radius. Wood activated carbon has a maximum pore radius generally, they are used for adsorption of larger molecules, and almost exclusively in the liquid phase. Water treatment in urban areas used in the first type of granular activated carbon that is made of wood, called charcoal. Coal activated carbon pore size in between.
