Definition and classification of carbon
Activated carbon is a kind of widely used adsorbent and catalyst. It is a kind of carbon containing raw material which is produced by carbonization and activation. Activated carbon is black, mainly composed of carbon elements. Its nature is stable, insoluble in water and organic solvents, such as the role of acid and alkali chemicals, and can be recycled through the recovery of its activity and repeated use. Activated carbon can be divided into powder, granular and fibrous three categories according to the appearance; according to the use of different raw materials can be divided into plant raw materials (wood, charcoal, etc.) mineral raw materials (coal, petroleum coke, etc.) and other raw materials (wood, paper pulp, hydrolysis of waste plastics) activated carbon produced by the way of making; it can be divided into gas activation remove activated carbon, chemical activation and activation of activated carbon and mixed remove activated carbon; use can be divided into gas phase adsorption by activated carbon (solvent recovery of activated carbon, carbon desulfurization etc.) and liquid phase adsorption by activated carbon (sugar, monosodium glutamate, carbon carbon carbon water treatment etc.) activated carbon and catalyst or catalytic agent carrier.
Bamboo carbon bamboo charcoal is a solid product obtained by carbonization at high temperature. According to the quality level can be divided into first grade, qualified two grades; according to the shape can be divided into cylinder carbon, carbon, carbon, carbon powder, etc.. In Japan, the final temperature of carbonization, some can be divided into 3 types: low temperature bamboo carbon 400 C, 600 C and 700 C of bamboo carbon and bamboo carbon high temperature 1000 DEG C; there are two types: 400 C and 600 C is called low temperature carbonization of bamboo carbon, 800 C and 1000 C the high temperature carbonization called bamboo carbon
And white carbon black carbon is usually divided into charcoal and white carbon black carbon, which can be divided into white carbon carbon and carbon black and white phillyraeoides carbon. White carbon, refers to the wood in a kiln at the end of hot carbonization Bachu from the kiln, then put out with wet sand mud, in the burning process, charcoal and air calcination, the external carbon is oxidized to produce white ash attached on charcoal. This carbon to hard, heavy, black, color section with metallic luster, when the sound of metal tapping will have a clear and melodious, burning without smoke, high heat, lasting combustion, little black powder drop, and is very suitable for the use of water purification and bath. Black carbon, obtained by the method of rotary kiln flameout, is contrary to white carbon. The old people in the past carbon brazier burned most of the carbon is burnt black carbonaceous rough. The utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model has the. It is easy to scattered black powder, not suitable for dishes, drinking water and bath, can be used for dehumidification and deodorization.
The definition and classification of carbon is a traditional and modern material. Carbon is a porous material, has a strong adsorption, humidity control, purification, deodorization and other functions. At present, there are some common charcoal, bamboo carbon, activated carbon, carbon black, coal and coke etc.. The national standard (GB/T17664 - 1999) in the definition of hardwood charcoal, charcoal with hardwood and pine charcoal carbon. Hardwood charcoal by the mixed material of hardwood and birch wood burning quality and. By hard and soft broad-leaved hardwood charcoal burning matter and mixed material. Pine charcoal is made from pine or coniferous wood
