[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of mixed aromatics, mixed aromatics are.

Mixed aromatic properties

Mixed aromatics are chemical mixtures composed of a variety of aromatic hydrocarbons, common aromatic hydrocarbons include benzene, toluene, xylene and ethylbenzene. Aromatics have a planar structure, the molecule contains one or more benzene rings, and its bond length is between single and double bonds, showing special stability. The physical properties such as boiling point, density and solubility of the mixed aromatics depend on their specific ingredients and proportions. In general, mixed aromatics have a high boiling point and density, and are insoluble in water, but soluble in organic solvents.

Mixed Aromatic Uses

Mixed aromatics are widely used in many industrial fields. In the chemical industry, they are important raw materials for the production of various chemicals, such as phenol, styrene and adipic acid. In the oil and gas industry, mixed aromatics are commonly used as raw materials for plasticizers, rubber, resins and fibers. Mixed aromatics are also used in the production of paints, solvents and dyes. In the field of fuel, mixed aromatics can be used as additives for high octane gasoline to improve the anti-knock and combustion efficiency of fuel.

Mixed aromatics upstream and downstream feedstocks

The production of mixed aromatics depends on the refining process of oil and natural gas. Upstream feedstocks mainly include crude oil and natural gas, which are converted to aromatics through processes such as catalytic reforming, cracking and hydrodearomatization. Catalytic reforming is the most commonly used production method. Through reforming the light fraction of crude oil, dehydrogenation, isomerization and cyclization reactions are carried out under the action of platinum aluminum catalyst to produce mixed aromatics such as benzene, toluene and xylene. Downstream products include a wide range of chemicals, solvents and high-performance materials, which are widely used in the chemical, pharmaceutical, textile, construction and automotive industries.

Mixed aromatic hydrocarbon storage methods

Due to the flammable and explosive nature of mixed aromatics, their storage requires special measures. Storage facilities should have a good ventilation system to prevent steam accumulation. The storage tank shall adopt explosion-proof design to avoid fire caused by static electricity accumulation. An automatic fire extinguishing system and gas detection equipment should be provided to detect and deal with leaks in time. Mixed aromatics storage tanks are usually made of carbon steel or stainless steel materials and are lined with anti-corrosion coatings to prevent chemical corrosion. The storage area should be far away from fire, heat and strong oxidant, and set up obvious danger signs.

Mixed Aromatics Market Analysis

The mixed aromatics market is influenced by a variety of factors, including crude oil prices, downstream demand and environmental policies. The price of crude oil directly affects the production cost of mixed aromatics, while the development of downstream industries, such as changes in demand in the automotive and construction industries, will also affect market demand. In terms of environmental protection policies, countries have increasingly stringent restrictions on the emission of volatile organic compounds (VOC), which puts forward higher environmental protection requirements for the production and use of mixed aromatics, prompting companies to improve processes to reduce pollution. Global energy restructuring and the development of new energy sources have also had a profound impact on the mixed aromatics market.

Mixed aromatics in the future

With the progress of science and technology and industrial upgrading, the mixed aromatics industry is facing new development opportunities and challenges. The development of green chemical technology is one of the important trends, through the use of cleaner production processes and catalyst improvements to reduce pollutant emissions in the production process. The rise of circular economy urges enterprises to strengthen the recycling of mixed aromatic waste and improve the efficiency of resource utilization. In terms of market demand, with the development of high-performance materials and new chemicals, the application field of mixed aromatics will be further expanded. For example, the application potential of mixed aromatics in new energy batteries, electric vehicles and high-end electronic materials is huge.

Conclusion

As an important chemical raw material, mixed aromatics has a wide range of applications and market prospects. Its production relies on the refining of oil and natural gas, obtained through processes such as catalytic reforming. Mixed aromatics require strict safety measures during storage and use to prevent accidents. On the market side, affected by crude oil prices, downstream demand and environmental protection policies, the mixed aromatics industry needs to continue to innovate and upgrade to meet challenges and seize opportunities. In the future, with the development of green chemical technology and circular economy, mixed aromatics will show broad application prospects in more emerging fields.
