FDCA绿色电合成技术国际领先

Core Viewpoint - The collaboration between Beijing University of Chemical Technology, Tsinghua University, and Quzhou Resource Chemical Innovation Research Institute has achieved a significant technological advancement in hydrogen production and chemical synthesis, demonstrating international leadership in the field [2][3]. Group 1: Technological Achievements - The newly developed 10 kW electrolysis technology for hydrogen production coupled with green oxidation to produce 2,5-furandicarboxylic acid (FDCA) has been evaluated and recognized as reaching an internationally leading level [2]. - The innovative concept of coupling water electrolysis with oxidation has been validated, revealing the mechanism of active oxygen generation through controlled activation of water at the anode interface [2]. - The project team has successfully designed and built a 20 kW electrolysis device, achieving a maximum current density of 1.0 A/cm², with FDCA production capacity of 56 tons/year and hydrogen production capacity of 27,240 standard cubic meters/year [3]. Group 2: Performance Metrics - The device demonstrated a 94.2% single-pass conversion rate of 5-hydroxymethylfurfural (HMF) at 7 kW operating power, with a Faradaic efficiency of 89.5% for FDCA and a selectivity of 95.0% [3]. - The space-time yield was recorded at 3.48 kg/m² per hour, with a production rate of 2.22 kg/hour for FDCA and a hydrogen production rate of 1.07 standard cubic meters/hour [3]. Group 3: Intellectual Property and Research Output - The project has resulted in the authorization of 4 national invention patents, 5 utility model patents, 2 PCT patent applications, and 1 registered trademark, along with the publication of 29 SCI papers [3].
