“…We determined an MSP of CPON as the highest energy material when net present value becomes 0 ($1.79/kg of CPON) by using a discounted cash flow analysis [1,5,19,20] based on the operating and annualized capital costs, assuming that the selling prices of BO and PG solvent are fixed to $1.15/kg and $0.06/kg, respectively. Figure 9 shows the cost contributions of each step in the Catalytic co-production of bioenergy and bio-based products S. Kim and J. Han process to the MSP.…”

“…Catalytic production of bio-based fuels using lignocellulosic biomass as a feedstock has gained increasing attention as a possible replacement for petroleum-based fuels [1][2][3]. Lignocellulosic biomass comprising hemicellulose (C 5 ), cellulose (C 6 ), and lignin should be first fractionated by a pretreatment [1,4].…”

Summary This study presents an integrated strategy for the co‐production of bioenergy (biofuels: butene oligomers) and bio‐based products (biomaterials: cyclopentanone (CPON) and alkylphenols) from hemicellulose (C5), cellulose (C6), and lignin fractions of lignocellulosic biomass based on experimental catalysis studies. To evaluate techno‐economic feasibility of the strategy, we performed a system‐level design study with three steps: process synthesis, energy analysis, and economic analysis. The results of process synthesis show that all biomass fractions are effectively converted with high numerical carbon yields (C6‐to‐butene oligomers: 52.5%, C5‐to‐CPON: 68.2%, and lignin‐to‐alkylphenols: 13.3%) but an efficient separation system for high recovery of bioenergy and bio‐based products is crucial. Moreover, an efficient design of a heat exchanger network leads that the total energy requirements of the process are satisfied by the combustion of biomass degradation products (humins). Finally, an economic analysis is performed to estimate the minimum selling price of CPON as the highest energy material (201 Mt/day of CPON production using 2000 Mt/day of corn stover feedstock processing). This result shows that the process ($1.79/kg CPON) can be cost competitive with current petro‐based production approaches. Copyright © 2017 John Wiley & Sons, Ltd.
