The nature and use
of coke in the field of chemical production raw materials
Abstract:
This paper discusses the nature and use of coke in the field of chemical production raw materials in detail. As an important chemical raw material, coke has the characteristics of high carbon content, high temperature strength, low ash content and good reactivity, so it has a wide range of applications in the production of chemical products. In this paper, the properties of coke are analyzed in detail, and its main applications in chemical production are introduced, including steelmaking, gasification, ammonia synthesis and electrode manufacturing.

1. Introduction

coke is a solid carbonaceous fuel, mainly from coal under high temperature conditions and dry distillation. Because of its good physical and chemical properties, coke has a wide range of applications in the field of chemical production raw materials. An in-depth understanding of the nature and use of coke will help to make better use of coke resources and improve the quality and efficiency of chemical production.

2. the properties of coke

1. physical properties: coke is usually black, porous solid, with high carbon content (generally more than 90%) and low volatile. Its density is about 1.8-2.1g/cm³, porosity is about 30%-50%.
2. Chemical properties: Coke has good chemical stability and can react with oxygen, carbon dioxide and other gases at high temperatures. In addition, coke has good reducibility and can reduce many metal oxides.

3. the use of coke

1. Steelmaking: Coke is an important fuel and reducing agent in the steelmaking process. At high temperatures, the coke reacts with oxygen to form carbon monoxide, which in turn reduces the iron oxides to elemental iron. In addition, coke can also be used as a burden, play a skeleton role, support the steel-making process of the material column.
2. Gasification: Coke can be used as gasification raw materials, and steam or oxygen and other gases at high temperature gasification reaction, hydrogen, carbon monoxide and other combustible gases, for the production of ammonia, methanol and other chemicals.
3. synthetic ammonia: in the production of synthetic ammonia, coke can be used as a reducing agent, and nitrogen in the air under high temperature and high pressure conditions to generate ammonia.
4. Electrode manufacturing: Coke has good conductivity and high temperature strength, so it is often used to manufacture electrodes for high temperature arc equipment such as electric arc furnaces and calcium carbide furnaces.

4. conclusion

coke has a wide range of applications in the field of chemical production raw materials, its main properties include high carbon content, high temperature strength, low ash and good reactivity. These properties make coke play an important role in the fields of steelmaking, gasification, ammonia synthesis and electrode manufacturing. In order to make better use of coke resources and improve the quality and efficiency of chemical production, it is necessary to have an in-depth understanding of the nature and use of coke.
