Description
An activated carbon carbonization furnace Technical Field
[0001] The invention relates to an activated carbon preparation device, in particular to an activated carbon carbonization furnace. Background Art
[0002] Activated carbon is a specially treated carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated in an airtight environment to reduce non-carbon components (a process called carbonization). The carbon is then reacted with gases, eroding the surface and producing a structure with well-developed micropores (a process called activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point-like, resulting in countless tiny pores on the surface of the activated carbon. The diameter of the micropores on the surface of activated carbon is mostly between 2 and 50 nm. Even a small amount of activated carbon has a huge surface area. The surface area of each gram of activated carbon is 500-1500 m 2 Almost all applications of activated carbon are based on this characteristic of activated carbon.
