In the field of raw materials for chemical production, there are various methods for manufacturing carbon black, mainly including furnace method, tank method, thermal cracking method, and acetylene black method. This article will provide a detailed introduction to these manufacturing methods, so that readers can have a comprehensive understanding of the production process of carbon black

1、 The furnace method is the main method for producing carbon black, which can be divided into oil furnace method, gas furnace method, and oil gas co firing method. The oil furnace method uses fuel oil as the raw material and burns it in the furnace to produce carbon black. The gas furnace law uses natural gas or coal gas as the main raw material to produce carbon black through combustion. The oil gas co firing method combines the characteristics of the oil furnace method and the gas furnace method, and can simultaneously use fuel oil and natural gas or coal gas as raw materials

The process of producing carbon black using the oil furnace method includes steps such as raw oil atomization, combustion, cracking, condensation, and generation of carbon black particles. After high-temperature atomization, the raw oil forms small oil droplets, which are burned and cracked in the air to produce carbon black

The gas furnace rule is to mix natural gas or coal gas with air and introduce it into the combustion chamber for combustion, generating carbon black. The production process of gas furnace method is relatively simple and easy to operate, but the output is relatively low

3. The oil gas co firing method combines the advantages of the oil furnace method and the gas furnace method, and can flexibly adjust the ratio of oil and gas according to market demand and raw material prices to achieve the best economic benefits

2、 The production of carbon black using the slot method mainly uses channel steel as a reactor, heating the raw oil or natural gas to high temperature, introducing it into the channel steel, and cracking it to produce carbon black. The slot method production process is relatively simple, but the production efficiency is low and the product quality is also poor

3、 Thermal cracking method is a method of cracking hydrocarbon compounds into carbon black at high temperatures under anaerobic or anaerobic conditions. The carbon black produced by this method has the characteristics of small particle size, large specific surface area, and high structure, so it has high value in some special application fields

4、 Acetylene black method is a method of generating carbon black through the pyrolysis of acetylene gas. At high temperatures, acetylene gas undergoes pyrolysis reactions, producing carbon black and hydrogen gas. The carbon black produced by acetylene black method has high conductivity and chemical stability, and is therefore widely used in fields such as batteries and electrodes

In summary, there are various methods for manufacturing carbon black, each with its own characteristics and applicable fields. In actual production, suitable manufacturing methods can be selected based on factors such as market demand, raw material prices, and production costs. At the same time, with the continuous progress of technology and the increasing environmental requirements, the carbon black manufacturing process is also constantly improving and optimizing to improve production efficiency, reduce energy consumption, and reduce environmental pollution.
