The difference between coal chemical engineering and chemical engineering and technology

Analysis of the difference between coal chemical industry and petrochemical industry

1. Raw materials
The petrochemical industry is a processing industry that produces petroleum products and petrochemical products from petroleum and natural gas. The outstanding feature of petrochemical industry is that there are many varieties and wide range of chemicals.
Coal chemical industry is a processing industry that produces various chemicals from coal, with the purpose of realizing the comprehensive utilization of coal energy. The prominent feature of coal chemical industry is the chemical conversion of coal into gas, liquid and solid products and then further processing.
The traditional coal chemical industry is the production of coke by dry distillation of coal, and the by-products are coke oven gas and coal tar, mainly to cooperate with the iron and steel industry, and the general ammonia synthesis process is also classified as the traditional coal chemical industry. Modern coal chemical industry is to convert coal into syngas, fine chemical products, etc. through advanced means such as liquefaction, gasification, hydrogenation, etc. Its main development directions are: 1. Coal to olefins; 4. Coal-based ethylene glycol; 5. Coal-based fine chemicals.
