纯苯专题：纯苯海外供应格局和中国进出口情况

1. Report Industry Investment Rating There is no information provided regarding the report's industry investment rating. 2. Core Viewpoints of the Report - The report analyzes the overseas supply pattern of pure benzene, including regional and national capacity distribution, and the impact factors on benzene supply in different countries and regions through the proportion of different production processes [2]. - It also examines China's import - export situation of pure benzene, highlighting that South Korea is the main source of China's imports, and the demand for gasoline in the United States can affect the volume of China's imports from South Korea [2]. 3. Summary According to the Table of Contents 3.1 Overseas Pure Benzene Supply Pattern 3.1.1 Overseas Pure Benzene Capacity by Region and Country - Asia has the most concentrated pure benzene production capacity, followed by Europe, North America, Southeast Asia, and the Middle East. China ranks first in the world in terms of capacity, and the top three overseas countries are the United States, South Korea, and Japan [2][7]. - China accounts for 30% of the global pure benzene capacity. Northeast Asia (excluding China) accounts for 18%, Europe 15%, North America 13%, and Southeast Asia 12%. Among overseas countries, the United States accounts for 16% of overseas capacity, South Korea 14%, and Japan 9% [7][8][9]. 3.1.2 Overseas Pure Benzene Production Process Capacity Distribution - The main supply source of pure benzene both in China and overseas is reforming, accounting for 49%. Overseas, ethylene cracking accounts for 30% (higher than China's 25%), and toluene disproportionation accounts for about 12% (lower than China's 24%). Overseas toluene demethylation accounts for 6% (higher than China's 2%) [12][13]. - In the United States, catalytic reforming accounts for 56%, ethylene cracking 22%, and toluene disproportionation 15%. In South Korea, catalytic reforming accounts for 43%, and toluene disproportionation accounts for 26%. In Japan, reforming accounts for 38%, and HDA accounts for 16% [16][20]. - In Western Europe, ethylene cracking accounts for 56%, catalytic reforming 29%, and HDA 9%. In Southeast Asia, reforming accounts for 59%, and ethylene cracking 28%. In the Middle East, reforming accounts for 79%, and ethylene cracking has a lower proportion [20][22]. 3.2 China's Pure Benzene Import - Export Pattern and South Korea's Pure Benzene Export Pattern 3.2.1 China's Pure Benzene Import - Export Pattern - China mainly imports pure benzene, and the export volume is negligible. The import dependence has been in the range of 15% - 18% in recent three years [27]. - In 2024, South Korea was China's largest source of pure benzene imports, accounting for 50% of the total imports. Other major sources include Brunei and Thailand, accounting for 12% and 11% respectively [28]. 3.2.2 South Korea's Pure Benzene Export Pattern - South Korea is the world's main exporter of pure benzene. In 2024, China was its main export destination, accounting for 71%, followed by the United States at 19% [35]. - The demand for gasoline in the United States affects the supply of aromatic components in the United States, which in turn affects South Korea's exports to the United States and then China's imports from South Korea [2][35]. - Since the second half of 2024, the total gasoline inventory in the United States has rebounded rapidly. In the first half of 2025, the inventory depletion rate was slow. The price difference between the US and South Korea was low, and South Korea sent more pure benzene to China, resulting in a 63% year - on - year increase in China's pure benzene imports from January to May 2025 [37][38].
