The role of activated carbon in the filter Activated carbon is a porous carbonaceous material. It has a highly developed pore structure and is an excellent adsorbent. The adsorption area per gram of activated carbon is equivalent to eight tennis balls. Adsorption is achieved through physical adsorption forces and chemical adsorption forces. Its constituent materials contain a small amount of hydrogen, nitrogen, oxygen, and ash in addition to carbon, and its structure is the formation of six rings of carbon accumulation. Made. Due to the irregular arrangement of the six rings of carbon, the activated carbon has a microporous volume and a high surface area.
Activated carbon can be made from a variety of carbonaceous materials including wood, sawdust, coal, coke, peat, lignin, kernels, hard husks, sucrose pulp, bone, lignite, petroleum residues, and the like. Among them, coal and coconut shells have become the common raw materials for the production of activated carbon.
Coconut shell activated carbon can be made from a variety of carbonaceous materials including wood, sawdust, coal, coke, peat, lignin, kernels, hard husks, sucrose pulp, bone, lignite, petroleum residues, and the like. Among them, coal and coconut shells have become the common raw materials for the production of activated carbon. The production of activated carbon is basically divided into two processes, which include dehydration and carbonization, heating of the raw materials, drying at a temperature of 170 to 600°C, and carbonization of about 80% of the original organics. The second process is to activate the char, which is done by reacting with char with an activator such as steam, which produces a mixture of CO and H2 in the endothermic reaction to burn and heat the char to the appropriate temperature (800 To 1000 °C) to burn out all of the decomposable substances, resulting in a well-developed microporous structure and a large specific surface area, which has a strong adsorption capacity.
