科技成果 | 南昌大学：生物基中链二元羧酸的创新工艺开发

Core Viewpoint - The article discusses the advancements in non-grain biomass utilization, highlighting innovative research outcomes and their commercial viability in the bio-based sector, particularly focusing on the development of bio-based dicarboxylic acids [2][3]. Summary by Sections Event Overview - The fifth Non-Grain Biomass High-Value Utilization Forum will be held from November 27-29 in Hangzhou, Zhejiang, focusing on innovative research results and commercial feasibility in the non-grain bio-based field, with over 1500 technology and project connections completed to date [2]. Innovation Achievements - The article presents the innovative development of bio-based medium-chain dicarboxylic acids (C5-C8), which include glutaric acid, adipic acid, heptanedioic acid, and octanedioic acid, with a global market size exceeding 20 billion and continuing to expand [5]. Technical Advantages - The project utilizes biomass-derived platform compounds (such as glycerol, furfural, and 5-hydroxymethylfurfural) to create a renewable supply chain for producing bio-based dicarboxylic acids, significantly reducing reliance on petroleum and lowering carbon emissions compared to petrochemical routes [7][8]. Production Process - The innovative one-step dicarbonylation synthesis technology achieves product selectivity of ≥85% and catalyst recovery rate of ≥99.99%, shortening production cycles and reducing overall costs, addressing high energy consumption and cost challenges [7][8]. Market Compliance - Bio-based products are certified for carbon footprint, overcoming international green barriers and filling the gap in high-end applications for domestic bio-based C5-C8 dicarboxylic acids, creating a competitive advantage through "cost reduction - green compliance - market adaptation" [8]. Intellectual Property and Collaboration - The project has published five domestic patents and is open to collaborative development, result transformation, or intellectual property transfer [9].
