An integrated strategy of multiple catalytic conversions was developed to completely utilize three major fractions of biomass, thereby increasing the revenue from lignocellulosic biomass (white birch). Cellulose was converted into 1,6-hexanediol (1,6-HDO) with a yield of 21.8% via a series of catalytic conversions, hemicellulose was converted into furfural with a yield of 87.2% via dehydration, and lignin was purified into high-purity lignin with a yield of 71.7% via two-step purification. Heat integration was performed to mitigate the challenges associated with the large energy requirements of the process. Additionally, a techno-economic analysis was conducted to investigate the feasibility of the proposed process. The minimum selling price (MSP) of 1,6-HDO is estimated to be $3,922/ton, meaning that the economics of the proposed process are favorable compared to petroleum-derived 1,6-HDO production ($4,400/ton). The effect of economic parameters on the MSP of 1,6-HDO was also investigated via a wide array of sensitivity analyses.
开发了一种多催化转化的综合策略，以充分利用生物质的三大主要成分，从而提高木质纤维素生物质（白桦）的收益。通过一系列催化转化，纤维素转化为产率为 21.8%的 1,6-己二醇（1,6-HDO），半纤维素通过脱水转化为糠醛，产率为 87.2%，木质素通过两步纯化转化为高纯度木质素，产率为 71.7%。进行了热集成以缓解该过程对大量能源需求的相关挑战。此外，还进行了技术经济分析以研究所提出工艺的可行性。1,6-HDO 的最低销售价格 (MSP) 估计为 3922 美元/吨，这意味着与石油衍生的 1,6-HDO 生产（4400 美元/吨）相比，所提出工艺的经济性有利。还通过广泛的敏感性分析研究了经济参数对 1,6-HDO 的 MSP 的影响。
