A new process for the production of 1,5-pentanediol (1,5-PDO) from biomass-derived furfural is studied. In this process, furfural is converted to 1,5-PDO in a high overall yield (80%) over inexpensive catalysts via multiple steps involving hydrogenation, dehydration, hydration, and hydrogenation subsequently. To effectively recycle H₂ as well as recover 1,5-PDO, detailed separation subsystems have been designed and integrated with reaction subsystems. Furthermore, a pioneer plant analysis is performed to estimate the risk on the cost growth and plant performance shortfalls. The integrated process leads to a minimum selling price of $1973 ton^–1 for 1,5-PDO, which suggests that it could be a promising approach for converting biomass into oxygenated commodity chemicals, which are difficult to produce from petroleum-derived feedstocks. The sensitivity analysis also identifies that the most important economic parameters for the process include the furfural feedstock price and plant size.

糠醛向1,5-戊二醇的转化：过程合成与分析

研究了一种由生物质衍生的糠醛生产1,5-戊二醇（1,5-PDO）的新方法。在该方法中，糠醛通过廉价的催化剂，经涉及氢化，脱水，水合和随后氢化的多个步骤，以高的总收率（80％）转化为1,5-PDO。为了有效地循环利用H ₂并回收1,5-PDO，已经设计了详细的分离子系统并将其与反应子系统集成在一起。此外，还进行了先锋工厂分析，以估算成本增长和工厂绩效不足的风险。集成过程导致最低销售价格为1973吨^–1对1,5-PDO的研究表明，这可能是将生物质转化为含氧商品化学品的有前途的方法，而这些化学品很难用石油衍生的原料生产。敏感性分析还确定，该工艺最重要的经济参数包括糠醛原料价格和工厂规模。
