As an environmentally friendly core chemical raw material, hydrogen peroxide (H₂O₂) plays a crucial role in the global industrial system. Data shows that in 2024, China's hydrogen peroxide production capacity exceeded 29 million tons per year (calculated at 27.5% concentration), accounting for over 70% of the world's total capacity, maintaining its leading position in the global market. Currently, the industry presents a pattern of "mainstream process-led upgrading and accelerated breakthroughs in emerging technologies," and is stepping into a new stage of green, intelligent, and large-scale development driven by policy guidance and market demand.
     Anthraquinone process, as the global dominant technology (accounting for over 90%), has achieved high maturity after more than 70 years of technological iteration. Enterprises such as Sinopec and Evonik have taken the lead in technological innovation, with fluidized bed reactors gradually replacing traditional fixed beds. Catalysts are shifting towards non-precious metalization, and Co-N-C single-atom catalysts have reduced costs by 60%. Environmental performance continues to improve, and the three-stage tail gas treatment system has reduced VOCs emission concentration to below 5mg/m³, far exceeding national standards. The new regulations issued by the Ministry of Emergency Management in 2025 explicitly prohibit the acid-alkali alternating process, and 122 existing devices will complete transformation within 5 years, further enhancing the inherent safety level of the industry.
     Direct synthesis method has emerged as the most promising emerging route, with the advantage of 100% atomic economy aligning with the development trend of green chemical industry. Teams from Peking University Shenzhen Graduate School, BASF, and others have made breakthroughs in catalyst research and development. The lignin-based single-atom Fe catalyst achieves 92% selectivity under normal temperature and pressure, and the stable operation time of the pilot plant has exceeded 1000 hours. With the optimization of membrane separation, biphasic system and other technologies, the product concentration has been increased to 12%, and the space-time yield is gradually approaching the level of anthraquinone process, making large-scale application promising.
     Downstream demand continues to expand, forming a diversified application pattern. The caprolactam industry chain accounts for 1/3 of the total hydrogen peroxide consumption, the green process of propylene oxide (HPPO) brings broad incremental space, and the demand in electronic-grade hydrogen peroxide and new energy materials fields shows explosive growth. Enterprises such as Sinopec and Huayi Qinzhou have laid out integrated projects to achieve efficient coupling between production and downstream applications, further consolidating industrial advantages.
