1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report The report conducts a comprehensive analysis of the downstream landscape of pure benzene, including both horizontal and vertical perspectives. Horizontally, it analyzes the demand proportion, production capacity growth rate, and regional distribution of the five major downstream products of pure benzene. Vertically, it focuses on the device analysis of each of the five products, including the proportion of self - owned and externally purchased pure benzene, device characteristics, regional distribution, and enterprise group concentration [2]. 3. Summary According to the Directory 3.1 Pure Benzene Downstream Pattern Horizontal Analysis 3.1.1 Demand Proportion and Basic Introduction of Five Major Downstream Products for Pure Benzene - Based on 2024 production data, the demand proportions of benzene ethylene, caprolactam (CPL), phenol (phenol - ketone), aniline, and adipic acid for pure benzene are 42%, 21%, 17%, 12%, and 7% respectively, with other pure benzene demands accounting for 1% [9]. - Benzene ethylene is the largest downstream product of pure benzene. Its production processes mainly include ethylbenzene dehydrogenation, propylene oxide - styrene co - production (PO/SM), and C8 extraction. It is mainly used in PS, EPS, ABS, UPR, etc. [11]. - CPL is the second - largest downstream product, mainly produced by the cyclohexanone ammoximation method (HAO, 83%) and the phosphoric acid hydroxylamine method (HPO, 17%). It is mainly used to produce PA6, which is used to make nylon [15]. - Phenol (phenol - ketone) is the third - largest downstream product. Produced by the cumene method, it is co - produced with acetone. Its main downstream products are bisphenol A and phenolic resin [22]. - Aniline accounts for 12% of pure benzene demand, produced by the nitrobenzene catalytic hydrogenation method. It is mainly used to produce MDI [23]. - Adipic acid accounts for 7% of pure benzene demand, mainly produced by the cyclohexene method (81%) and the cyclohexane method (19%). It is used to produce polyester polyols and PA66 [33]. 3.1.2 Demand Proportion of Five Major Downstream Products for Pure Benzene (Weighted by the Proportion of Externally Purchased Pure Benzene) - After excluding self - owned pure benzene integrated production capacity, the demand proportions of caprolactam, benzene ethylene, phenol - ketone, aniline, and adipic acid for externally purchased pure benzene are 28%, 25%, 15%, 19%, and 12% respectively [38]. - Benzene ethylene has a higher proportion of self - owned pure benzene in integration, with externally purchased pure benzene device capacity accounting for 34%. Phenol has 51% externally purchased capacity, CPL has 76%, and aniline and adipic acid have 94% and 95% respectively [37]. 3.1.3 Production Cycle of Five Major Downstream Products - Benzene ethylene's high - speed production cycle from 2020 - 2023 has ended, and production has slowed down since 2024 [42]. - CPL's production growth rate slowed down to 10% in 2025 after reaching 16% and 21% in 2023 and 2024 respectively [42]. - Phenol's production growth rate slowed down to 13% in 2025 after an average of 23% from 2020 - 2024 [42]. - Aniline's production growth rate is 8% in 2025, with intermittent production increases in the past [42]. - Adipic acid had no production plan in 2025 after a large - scale production increase in 2023 [42]. 3.1.4 Regional Consumption Proportion of Pure Benzene and the Demand Proportion of the Five Major Downstream Products in Each Region - The main consumption area of pure benzene is East China, which is also the main trading market. Other regions have relatively small proportions [45]. - In East China (excluding Shandong), benzene ethylene accounts for 58% and phenol accounts for 23% of pure benzene demand [46]. - In Shandong, benzene ethylene accounts for 36% and CPL accounts for 22% of pure benzene demand, with a more evenly distributed downstream structure compared to East China [46]. - In North China and South China, benzene ethylene and CPL are the main downstream products [49]. 3.2 Pure Benzene Downstream Pattern Vertical Analysis 3.2.1 Benzene Ethylene Device Analysis - Self - owned pure benzene devices in benzene ethylene production mainly belong to Sinopec, CNOOC, PetroChina, and large refineries like Hengli, Zhejiang Petrochemical, etc. Externally purchased pure benzene devices are mainly private refineries in Shandong and Jiangsu - Zhejiang [50]. - Benzene ethylene devices are mainly distributed in East China (43%), South China (19%), Shandong (18%), and Northeast China (10%). Externally purchased pure benzene devices are mainly in East China (50%) and Shandong (39%) [54]. 3.2.2 CPL Device Analysis - Self - owned pure benzene devices in CPL production mainly belong to Sinopec and its joint - venture companies. Most devices are externally purchased [57]. - CPL devices are mainly distributed in Central China (28%), Shandong (27%), and South China (26%). The enterprise concentration is not high [59]. - About 44% of CPL devices have downstream PA6 devices, and 21% have downstream PA6 and nylon devices [59]. 3.2.3 Phenol Device Analysis - Self - owned pure benzene devices in phenol production mainly belong to Sinopec, PetroChina, CNOOC, and large private refineries. Externally purchased pure benzene devices are in East China, Shandong, and South China [62]. - 69% of phenol devices have downstream bisphenol A devices, and 35% of these have self - owned bisphenol A and PC devices [62]. - Phenol devices are mainly in East China (49%), Shandong (19%), and South China (13%). The enterprise concentration is not high [68]. 3.2.4 Aniline Device Analysis - Only 6% of aniline devices have self - owned pure benzene (Sinopec Nanjing Chemical). Most are externally purchased [69]. - Aniline devices are mainly in East China (37%) and Shandong (33%). Wanhua accounts for 48% of the total production capacity, with high industry concentration [71]. 3.2.5 Adipic Acid Device Analysis - Only 5% of adipic acid devices have self - owned pure benzene (PetroChina). Most are externally purchased [73]. - Adipic acid devices are mainly in Southwest China (34%) and Shandong (25%). Huafeng accounts for 34% of the total production capacity. The industry is in an over - supply and loss situation [77].
