The pylene tetramethylbenzene industry is highly concentrated and its production capacity is gradually expanding.

Methylene is currently the only tetramethylbenzene with industrial use among polytoluenes. Methylene is an intermediate product in the production of high-temperature resins, special coatings, plasticizers and curing agents. Because its methyl group is very active, has high selectivity and high reaction speed, it has attracted more and more attention in industry.

In recent years, although some pylenetetramethylbenzene companies have withdrawn from production under the background of stricter environmental protection policies, at the same time, with the expansion of the production scale of pyromellitic dianhydride, the market demand for pyromellitic acid dianhydride has increased. Driven by the demand , Jiangsu Zhengdan Chemical Industry Co., Ltd., Shandong Minghua New Materials Co., Ltd. and other companies have deployed the production of pyrene, promoting the gradual expansion of the production capacity of the domestic pyrene industry. According to the “China Pylene Industry Market In-depth Research and Development Prospects Report 2023-2028” released by the Industrial Research Center, in 2022 , China’s pyrene industry production capacity is 84,600 tons.

From the perspective of competition echelon division, Pengchen New Materials Co., Ltd. and Jiangsu Zhengdan Chemical Industry Co., Ltd. are in the leading position with tetramethylbenzene production capacity of 10,000 tons/year and above, belonging to the first echelon; Suzhou Jiutai Group Co., Ltd. , Jiangsu Hualun Chemical Co., Ltd. and other companies have production capacities of tetramethylbenzene between 5,000 tons/year and 10,000 tons/year, belonging to the second echelon; companies such as Nanjing Zhenxing New Energy Development Co., Ltd. have production capacities of tetramethylbenzene of 5,000 tons/year. Those below 20 years old belong to the third echelon of competition.

Judging from the price change trend, in recent years, the price of pyrene has shown a continuous downward trend. On the one hand, the optimization of production processes and the advancement of production technology have led to a decrease in the unit production cost of pyrene; on the other hand, the higher profit margins of the early pyrene industry attracted many investors, which intensified market competition and superimposed Changes in the price of upstream raw materials have caused the price of pyrene in China to decline day by day, from 23,400 yuan/ton in 2017 to 9,500 yuan/ton in 2022.

From the perspective of production technology, the production methods of pyrene can be divided into synthesis methods and separation methods. Due to the high production cost of synthesis methods, as market competition intensifies, product prices decline. Due to cost control factors, synthesis methods have gradually In the future, under the background of increasing environmental protection standards, to avoid resource waste and environmental pollution, the technical route of comprehensive utilization of C10 aromatic hydrocarbon resources to produce pyrene will remain the mainstream of China’s pyrene industry.

Industry analysts said that at present, the concentration of pylene tetramethylbenzene industry is relatively high, and the market share is mainly occupied by Pengchen New Materials Co., Ltd. , Jiangsu Zhengdan Chemical Industry Co., Ltd., Suzhou Jiutai Group Co., Ltd., Jiangsu Hualun Chemical Co., Ltd., Nanjing Zhenxing New Energy Development Co., Ltd. and other enterprises. In addition to these companies, the pyrene project of Shandong Minghua New Materials Co., Ltd., a subsidiary of Mingquan Group, was successfully launched in 2021, and Haopu Technology Xingtai Co., Ltd. is planning to build a 10,000-ton pyrene production project. In the future, as projects under construction in the pyrene industry come into operation, the number of participants in the pyrene industry may increase, and the market concentration of pyrene may then decline.
