Carbon Black Usage And Synthesis

Production method

Natural gas tank method of making carbon black: take natural gas as raw material and use iron pipe to send it into the combustion chamber. The form of the combustion chamber can be either long and short and is made of iron plate. It contains a number of olefin burner inside it. Natural gas is sprayed with appropriate force from the burner nozzle and burned in the case of insufficient air, that is, to generate a bright and black smoke flame. The flame then goes directly into the channel iron with the distance between the burner and the slot surface being 65~80 mm. At this time, the temperature of olefin burning is reduced from about 1000 to 1400 ° C to about 500 ° C, and the carbon black is accumulated. The groove can move back and forth horizontally, with a moving speed of 3 to 4 mm/s. In order to maintain normal production, the required amount of air is about 2.5 to 3 times the theoretical calculation. The resulting carbon black was scraped into a funnel with a fixed doctor blade and sent to a central packing chamber for disposal. Then the carbon black is softened, filtered to remove the hard particles and scale and further sent into the mill grinding to enable more uniform thickness. However, the body is still very light and loose, thus should be shaken to a become a bit solid. Then add a small amount of water to the carbon black to make it into paste-like shape and have a small needle rotated inside it to forming micro-pellets, followed by drying to obtain the finished product. In the case of using pigment for carbon black, in order to facilitate the dispersion, the granulation is unnecessary. The process is as follows:
Raw gas, air → combustion cracking → collection → granulation → packaging → finished product.
Carbon black is one of the oldest industrial products. In ancient times, china has already applied incomplete combustion of vegetable oil for making pigment carbon black. In 1872, the United States first used natural gas as raw material to produce carbon black using tank method and mainly used it as a coloring agent. It was not until 1912 when Mott found the reinforcement effect carbon black on the rubber before the carbon black industry had gotten rapid development. Then it had successively developed of a variety of process methods. At present, oil furnace method is the most efficient and most economical method with the oil furnace black production amount accounting for  70-90% of the total carbon black production. There are mainly furnace, slot method, thermal cracking, three methods.
It is obtained by the carbonization of the plant material such as peat. It can also be derived from the carbonization of cocoa shell and beef bone or from the combustion of vegetable oil.

Carbon black is a finely divided form of carbon. It may ignite explosively if suspended in air in the presence of an ignition source or slowly undergo spontaneous combustion upon contact with water. In addition, it is toxic by inhalation, with a TLV of 3.5 mg/m3 in air. Primary uses are in the manufacture of tires, belt covers, plastics, carbon paper, colorant for printing inks, and as a solar-energy absorber.

finely divided black dust or powder

Chemical Properties

Carbon black (essentially elemental carbon), is a black or brown liquid or solid (powder). Odorless solid. Carbon black oil is flammable and has a petroleum odor.

Physical properties

Carbon black [1333-86-4] is virtually pure elemental carbon (diamond and graphite are other forms of nearly pure carbon) in the form of near-spherical colloidal particles that are produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons. Its physical appearance is that of a black, finely divided pellet or powder, the latter sometimes small enough to be invisible to the naked eye. Its use in tires, rubber and plastic products, printing inks and coatings is related to the properties of specific surface area, particle size and structure, conductivity and color.
It is in the top 50 industrial chemicals manufactured worldwide, based on annual tonnage. Current worldwide production is about 15 billion pounds per year (6.81 million metric tons). Approximately 90% of carbon black is used in rubber applications, 9% as a pigment, and the remaining 1% as an essential ingredient in hundreds of diverse applications.
Modern carbon black products are direct descendants of early “lampblack”, first produced in China over 3500 years ago. These early lampblacks were not very pure and differed greatly in their chemical composition from current carbon blacks. Since the mid-1970s most carbon black has been produced by the oil furnace process, which is most often referred to as furnace black.
Unlike diamond and graphite, which are crystalline carbons, carbon black is an amorphous carbon composed of fused particles called aggregates. Properties, such as surface area, structure, aggregate diameter and mass differentiate the various carbon black grades.


Carbon black Super-P (TIMCAL) was used as conductive agent. Super P furnace black the best conductive additive. Carbon black (conducting material, super P black) was added with binder in the composite electrode to compensate the low electrical conductivity of PPy and PPyDVB in miniemulsion polymerization. The hybrid Super P-SACNT conductive network manifests itself as a promising strategy to improve the battery performances with a minimum amount of conductive fillers.


Tire treads, belt covers, and other abrasion- resistant rubber products; plastics as a reinforc- ing agent, opacifier, electrical conductor, UV- light absorber; colorant for printing inks;carbon paper; typewriter ribbons; paint pigment; nucleat- ing agent in weather modification; expanders in bat- tery plates; solar-energy absorber (see note).


In the rubber, plastic, printing, and paint industries as a reinforcing agent and a pigment


A finely divided form of carbon, practically all of which is made by burning vaporized heavy-oil frac- tions in a furnace with 50% of the air required for complete combustion (partial oxidation). This type is also called furnace black. Carbon black can also be made from methane or natural gas by crack- ing (thermal black) or direct combustion (channel black), but these methods are virtually obsolete. All types are characterized by extremely fine particle size, which accounts for their reinforcing and pig- menting effectiveness.


A finely divided form of carbon produced by the incomplete combustion of such hydrocarbon fuels as natural gas or petroleum oil. It is used as a black pigment in inks and as a filler for rubber in tire manufacture.


carbon black: A fine carbon powdermade by burning hydrocarbons in insufficientair. It is used as a pigmentand afiller (e.g. for rubber).

General Description

Multi walled carbon nanotubes (MWNTs, CNTs) were prepared by chemical vapor deposition (CVD). In chemical vapor deposition (CVD), a volatile precursor undergoes thermal decomposition at elevated temperatures to form a solid deposit on a substrate. 1 Carboxylic acid groups can be attached to the defect sides and ends of the nanotube by treatment with oxidizing agents. Carboxylic acid groups can be easily derivatized into different functional groups.


Possible carcinogen. Bronchitis.

Health Hazard

There are no well demonstrated health hazards to humans from acute exposure to carbon black.
Commercial carbon black is a spherical colloidal form of nearly pure carbon particles and aggregates with trace amounts of organic impurities adsorbed on the surface. Potential health effects usually are attributed to these impurities rather than to the carbon itself. Soots, by contrast, contain mixtures of particulate carbon, resins, tars, and so on, in a nonadsorbed state.

Biochem/physiol Actions

The use of dextran-coated charcoal makes the immunoassay of insulin in biological fluids simpler and more rapid. In theory, the charcoal coated with dextran will adsorb the free hormone and leave hormones that are bound to a carrier (or antibody). Dextran coated charcoal is used to strip hormones from serum instead of charcoal alone, because there is less loss of protein using dextran coated charcoal.

Safety Profile

Mildly toxic by ingestion, inhalation, and skin contact. Questionable carcinogen. Mutation data reported. See also CARBON. A nuisance dust in high concentrations. We it is true that the tiny particulates of carbon black contain some molecules of carcinogenic materials, the carcinogens are apparently held tightly and are not eluted by hot or cold water, gastric juices, or blood plasma.

Potential Exposure

Used as reinforcing agent and filler for rubber; colorants for ink, paint, and plastics. Workers in carbon black production or in its use in rubber compounding, ink and paint manufacture, plastics compounding, drycell battery manufacture.
