my country’s hydrogenated benzene industry chain is relatively complete and the overall development trend of the industry is improving.

Hydrogenated benzene, also known as benzene hydrogenation, refers to the benzene mixture produced by hydrogenation, that is, the benzene mixture obtained by hydrogenation extraction of crude benzene. The hydrogenation method is a new environmentally friendly process for processing crude benzene. Through this process, high-purity benzene with higher purity can be produced, which is widely used in the production of many types of fine chemical intermediates and raw materials. At present, my country’s hydrogenated benzene production technology is mature, the industrial chain is complete, and the overall development trend of the industry is good.

The production methods of hydrogenated benzene are mainly divided into two categories: high temperature method (600-630℃) and low temperature method (320-380℃). Among them, the low-temperature method is currently the main method for hydrogenated benzene production in my country. Its mainstream process paths include extractive distillation and solvent extraction low-temperature hydrogenation processes. It refers to using crude benzene as raw material, through removal and recombination, light hydrogenation, catalyst The process of removing sulfur, nitrogen and other impurities through catalysis, high temperature and high pressure reaction, extractive distillation or solvent extraction process to obtain high purity benzene. After years of research and development, my country’s hydrogenated benzene production process has been basically mature.

The upstream of the hydrogenated benzene industry chain is the supply of raw material crude benzene. In the past two years, my country’s crude benzene production has continued to decline due to factors such as rising international crude oil prices, stricter national environmental protection policies, and company shutdowns caused by the epidemic. But now, with the negative situation gradually improving, local companies’ crude benzene projects are gradually put into production. For example, in November 2022, Shanxi Shenglong TEDA’s 25,000-ton crude benzene production capacity project entered construction. Against this background, my country’s crude benzene production has gradually recovered. In 2022, domestic crude benzene production will be approximately 4.658 million tons, a year-on-year increase of 1.7%. The continued recovery of crude benzene supply in the upstream and increasingly mature production processes have laid a good foundation for the development of the domestic hydrogenated benzene industry.

The downstream of the hydrogenated benzene industry chain is in the chemical industry, with specific applications in the production of chemical products such as styrene, phenol, aniline, acetone, cyclohexanone, and maleic anhydride. Take styrene as an example. Styrene is a key raw material for synthetic rubber, and its output will exceed 19 million tons in 2022. The rapid development of downstream application fields has brought broad demand space to the domestic hydrogenated benzene market, which in turn has driven its production to continue to increase. According to the “China Hydrogenated Benzene Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center Shows that domestic hydrogenated benzene production has reached 4.543 million tons in 2022.

Industry analysts said that driven by the rapid development of the downstream market, domestic hydrogenated benzene production projects continue to increase, and related projects include 2022 Bazhou Haixiang Petrochemical’s 400,000 tons/year crude benzene refining comprehensive utilization unit reconstruction and expansion project, Anhui Yupeng Chemical’s 100,000 tons/year crude benzene hydrorefining project, etc. In addition, my country’s hydrogenated benzene companies include Shandong Laiwu Steel, Zhanhua Yukai, Shandong Hongchang, Tangshan Dimu, Tangshan Xuyang, Tangshan Ruida, Jiangsu Zhongtai, Hebei Ruixin Jinhua, Hebei Jiantao, There are many companies such as Handan Yulong. In the future, as domestic hydrogenated benzene projects accelerate their production, the production capacity of hydrogenated benzene will continue to increase, and the industry has broad prospects for development.
