Manufacturing methods
of coal chemical industry
coal chemical industry refers to the use of coal as raw material, through chemical processing methods to convert coal into gas, liquid and solid products or semi-finished products, and then further processed into a series of chemical products or synthetic fuel industry. With the development of science and technology, the coal chemical industry has continuously introduced new technologies and new processes, and gradually developed into large-scale, large-scale and integrated development.

1. the basic principle of coal chemical industry
The basic principle of
coal chemical industry is to convert carbon, hydrogen and other elements in coal into gas, liquid or solid products under the action of high temperature, high pressure and catalyst. According to different process conditions and operation methods, coal chemical industry mainly includes coal gasification, liquefaction, dry distillation and coking processes.

2. Coal Chemical Manufacturing Methods

1. Coal Gasification

Coal gasification is the process of converting coal into combustible gas. Under the condition of high temperature and high pressure, by introducing gasification agent (such as oxygen, water vapor, etc.), the carbon in the coal reacts with the gasification agent to generate combustible gas with carbon monoxide and hydrogen as the main components. Coal gasification technology includes fixed bed gasification, fluidized bed gasification and entrained flow gasification.

2. Coal liquefaction

Coal liquefaction is the process of converting coal into liquid fuel. Under the action of high temperature, high pressure and catalyst, carbon, hydrogen and other elements in coal are converted into liquid fuels (such as gasoline, diesel, etc.). Coal liquefaction technology includes direct liquefaction and indirect liquefaction.

3. Coal carbonization

Coal carbonization is a process of heating and decomposing coal under the condition of isolating air. Through dry distillation, coke, coal tar, gas and other products can be obtained. Coal dry distillation technology mainly includes traditional dry distillation and high temperature dry distillation.

4. Coking
of coal
Coking of coal is a process in which coal is heated to a high temperature under the condition of isolating air, so that the coal decomposes and produces coke and coke oven gas. Coke is mainly used in iron and steel industry smelting, coke oven gas can be used as fuel or chemical raw materials.

3. the development trend of coal chemical industry

With the continuous progress of science and technology, the coal chemical industry is facing new challenges and opportunities. In the future, the development of coal chemical industry will pay more attention to environmental protection and resource utilization efficiency, develop in the direction of large-scale, large-scale and integration, and strengthen technological innovation and product research and development to improve the added value and market competitiveness of products.

4. coal chemical production safety and environmental protection requirements

coal chemical production process involves high temperature, high pressure, flammable and explosive and other risk factors, so safe production is very important. Enterprises need to establish a sound safety management system and operating procedures, strengthen the safety training and education of employees, and ensure the smooth progress of the production process.

At the same time, coal chemical production will also produce certain pollutants such as waste gas, waste water and solid waste. Enterprises need to take effective treatment measures to meet national environmental protection standards and protect the ecological environment.

In short, coal chemical industry is an important industrial field that uses coal as raw material and is converted into gas, liquid or solid products through chemical processing methods. With the continuous progress and application of science and technology, the coal chemical industry will continue to grow and make greater contributions to economic and social development.
