User akwuliang005 asked: Regarding the classification of the chemical industry. @akwuliang005 Answer: The typical characteristic of the chemical industry is process manufacturing, which involves using physical or chemical methods such as mixing, separating, crushing, and heating raw materials to increase their value. From the perspective of industry scope, the chemical industry can be divided into fuel chemicals, inorganic chemicals, organic chemicals, and fine chemicals. The following provides a brief overview of the classification concepts, characteristics, and industrial chains of these various types of chemical industries.

Fuel chemicals: Concept: Fossil fuels are processed (through thermal or catalytic methods) to undergo a series of physical and chemical changes, resulting in two main types of products: oil-based products and chemical products. Oil products: such as gasoline, diesel, lubricants, etc., mainly provide various liquid fuels and lubricants for transportation and mechanical power. Chemicals: Produce various products such as ethylene, propylene, toluene, acetylene, gas, and syngas, which serve as raw materials for manufacturing other household items such as **agents, disinfectants, paints, adhesives, soaps, detergents, fertilizers, and more. Industry chain:
Inorganic chemical engineering: The industry that uses natural resources and industrial by-products as raw materials to produce inorganic acids such as sulfuric acid, nitric acid, hydrochloric acid, and phosphoric acid, as well as chemical products like soda ash, caustic soda, synthetic ammonia, fertilizers, and inorganic salts. Application areas: It is involved in industries such as papermaking, rubber, plastics, pesticides, feed additives, trace element fertilizers, space technology, mining, oil extraction, navigation, the information industry and electronics industry within the field of high-tech, as well as various material industries. It is also closely related to people’s daily needs in terms of clothing, food, housing, and transportation, as well as industries such as light manufacturing, environmental protection, and transportation. Industry chain:
Organic and fine chemicals: The concept of organic chemistry is an industry that uses petroleum, coal, natural gas, and other raw materials to produce various organic substances； Fine chemicals refer to products (high-value-added products) that are characterized by small batch sizes, a variety of types, low investment requirements, and rapid results. Application areas: In 1986, the Ministry of Chemical Industry classified fine chemical products into 11 categories in order to standardize their classification, namely: 1. Pesticides ； 2. Dyes ； 3. Coatings (including paints and inks) ； 4. Pigments ； 5. Reagents and high-purity materials ； 6. Information-related chemicals (including photosensitive materials, magnetic materials, and other chemicals capable of receiving electromagnetic waves) ； 7. Food and feed additives ； 8, Adhesive ； 9. Catalysts and various additives ； 10. Chemicals (active pharmaceutical ingredients) and household chemicals produced by chemical manufacturing systems. 11. Functional polymer materials in polymeric polymers (including functional films, polarizing materials, etc.). Industry chain:
Industry value chain: The chemical industry is characterized by starting with raw materials such as coal, oil, and natural gas, processing them to produce a variety of intermediate products, and then carrying out various chemical reactions with different raw materials to create derived products that can be used in various aspects of daily life. This also leads to diversity in downstream industries and end-user demands. Processes and flow paths of some key products:
Very systematic; worth learning.* I’ve seen resumes for several professionals in inorganic non-metallic materials, and all of them are in the field of cement
