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 petroleumderived 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.
