There are many kinds of additives, and the production process is different. There are wood carbon, coal carbon, coke, graphite and so on. There are many kinds of different kinds. A high - grade carbon - carburizer generally refers to a graphitized carbon - based additive, which in high temperature is graphite in the microform of graphite. The graphite can reduce the content of impurities in the carburizing agent, increase the carbon content of the carbon and reduce the sulfur content.
The use of carburizer in casting can greatly increase the amount of scrap steel, reduce the amount of pig iron, or use no pig iron. The feeding method of furnace smelting should be put into the furnace with waste steel and other materials, and the small dosage can be added to the surface of the molten iron. However, it is important to avoid large quantities of iron and water in order to prevent excessive oxidative effects and insufficient carbon content of casting. The amount of carbon added is determined according to the ratio of other raw materials and carbon content. Different types of cast iron are selected according to the need to choose different types of carbon. The characteristics of the carburizing agent itself choose pure carbon graphitized material, reduce the impurities in pig iron, and the choice of carbon addition agent can reduce the production cost of the casting.

In the process of smelting, the carbon content in the steel can be added to the molten steel, due to the improper loading or loading and the excessive amount of decarburization. The commonly used additive is carbon iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. In converter smelting and high carbon steel, the use of petroleum coke with few impurities is used as a carbon extender. The requirement for the carbon dioxide of the converter steelmaking is high, the ash, volatile and sulfur, phosphorus, nitrogen and other impurities are low, and dry, clean, the particle size is moderate


Coconut shell activated carbon is a kind of carbonized material with multi-pore diameter. It has extremely rich pore structure and has good adsorption properties. Its adsorption effect combines physical and chemical absorption, and its appearance is black. Its ingredients except the main carbon, also contains a small amount of hydrogen, nitrogen, oxygen, and its structure looks like in a hexagon, due to the irregular hexagon structure, identified the more definite and also the characteristics of high surface area, per gram of activated carbon to the surface of the than equivalent to more than 1000 square meters.The products are mainly used for drinking water, purified water, liquor, beverage, industrial sewage purification, decoloring, dechlorination, deodorization. It can also be used in oil refining industry.


columnar activated carbon is made from fine wood chips and coconut shells, etc. It is made by crushing, mixing, extrusion, molding, drying, carbonization and activation. The feature is the non-adhesive forming activated carbon technology. Change the traditional method of forming traditional binder such as coal tar and starch. There is no adhesive component, the affinity between the carbon molecules and the special properties of the raw materials themselves. The scientific formulation, made, effectively avoids the carbon hole plugging, fully plays the adsorption function of rich developed carbon hole. The advantages are that the cylindrical activated carbon produced by the use of high quality wood chips and coconut shells is lower than the traditional coal ash, with less impurities, gas phase adsorption value and CTC as the absolute advantage. The product aperture distribution is reasonable, reaching the maximum adsorption and desorption, which can greatly improve the service life of the product (average 2-3 years), 1.4 times the average coal carbon. There are cylindrical and spherical particles and other specifications. Suitable for gas phase adsorption of organic solvent recovery (benzene, toluene, xylene gas, acetone recovery of acetate fiber industry) impurities and harmful gas, gas recovery oil refineries, gas station, oil depot too much gasoline.


Wood activated carbonis based on high quality wood as raw material, shape of powder, through high temperature carbonization, activation, and a variety of refined from process woodiness active carbon, has a large specific surface area, high activity, microporous developed, decoloring force is strong, large pore structure characteristics, pore structure is big, can have a large variety of material such as the adsorption of the liquid color and impurities.
Mainly used in food, alcohol, oil, beverage, dye, chemical, water purification, sewage treatment, COD, medicinal activated carbon, etc

The wood based activated carbon is made of fruit shell and wood chips, and the appearance is black fine powder. It is non-toxic, tasteless, has a larger surface area and better adsorption ability. Suitable for sugar, pharmaceutical, beverage, wine, food, printing and dyeing, paper making, chemical industry, industrial waste water purification, decolorization of organic solvent, deodorization, refining, purification and waste water treatment are also widely used.


Granular activated carbon is divided into finalize and unshaped particles. Ningxia Biyuan carbon co., LTD, is made of coconut shell, fruit shell and coal quality. Products are widely used in drinking water, industrial water, brewing, waste gas treatment, decolor, desiccant, gas purification and other fields. The particle activated carbon is made of high quality anthracite, which is refined and processed by advanced technology. It has developed pore structure, good adsorption property, high mechanical strength, easy to reproduce and low cost. Purification of toxic gases, waste gas treatment, purification treatment of industrial and living water, solvent recovery, etc.
Activated carbon filters work through carbon beds. Component carbon bed activated carbon particles have many microholes and huge surface area, and have strong physical adsorption capacity. Water passes through the bed of carbon, the organic pollutant in water is adsorbed by activated carbon. In addition, the non-crystalline parts of activated carbon have some oxygen tube groups, and the organic pollutants in the water through the carbon bed are effectively adsorbed by activated carbon. Activated carbon filter is a more commonly used water treatment equipment, water treatment desalination system can effectively guarantee the pretreatment stage equipment service life and improve water quality, pollution prevention, especially after level to prevent reverse osmosis membrane, ion exchange resin and so on more than pollution free oxygen toxicity. The main factors influencing the effect of carbon filtration adsorption and service life are: type and concentration of pollutants, retention time of air filtration materials, temperature and humidity of air. The actual choice is to determine the form of the filter and the type of activated carbon according to the type, concentration and treatment of pollutants, such as air conditions. The activated carbon filter and downstream shall have a good dust filter, and its efficiency specification shall not be lower than F7. Upstream filters prevent dust from blocking activated carbon materials; The downstream filter stops the activated carbon itself
