Use

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.
