2,5-Furan dicarboxylic acid (FDCA) is a promising intermediate for producing polyethylene furan dicarboxylate, an alternative to polyethylene terephthalate that combines a significantly lower greenhouse gas footprint with better mechanical and gas barrier properties. This work presents a process design and techno-economic evaluation for producing FDCA from non-edible biomass via the oxidation of furfural to furoate salt, and subsequent carboxylation to furandicarboxylate salt. Major technical uncertainties are associated with the possible polymerization of furfural in the oxidation step and the state of salt phase in the carboxylation step. Based on the furfural market price of $1400/ton this process requires a minimum selling price of 2000 ± 500 $/ton FDCA. To compete with purified terephthalic acid (PTA), it requires a premium of 100% for better performance and sustainability, or a combination of much cheaper furfural and a much lower capital expenditures (CAPEX). © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

糠醛到 FDCA：系统的工艺设计和技术经济评价

2,5-呋喃二甲酸 (FDCA) 是生产聚呋喃二甲酸乙二醇酯的一种很有前景的中间体，它是聚对苯二甲酸乙二醇酯的替代品，它结合了显着较低的温室气体足迹和更好的机械和气体阻隔性能。这项工作提出了一种工艺设计和技术经济评估，用于从非食用生物质通过糠醛氧化成糠酸盐，然后羧化成呋喃二甲酸盐来生产 FDCA。主要的技术不确定性与氧化步骤中糠醛可能的聚合和羧化步骤中盐相的状态有关。基于 1400 美元/吨的糠醛市场价格，此过程需要 2000 ± 500 美元/吨 FDCA 的最低销售价格。为了与精对苯二甲酸（PTA）竞争，它需要 100% 的溢价才能获得更好的性能和可持续性，或者更便宜的糠醛和更低的资本支出 (CAPEX) 的组合。© 2021 化学工业协会和 John Wiley & Sons, Ltd
