466853 Combined Biochemical and Thermochemical Processing of Lignocellulosic Biomass: Techno-Economic Evaluation
Moreover, many of these concepts are still in the development stage, which requires the use of process modeling techniques. Modelling of lab-scale based production processes allows for techno-economic analysis and optimization, as estimates of energetic efficiency and scale-up potential of novel conversion processes are lacking. Production feasibility will be highly dependent on the energetic efficiency, environmental sustainability, and economic potential of these bio-based fuels and chemicals, especially in comparison to their fossil-fuel derived counterparts.
This work presents techno-economic process models, using flowsheeting software, of co-production of value added products, liquid fuels, and heat from lignocellulosic feedstock to analyze and compare the annual costs and efficiencies of the different combined biochemical and thermochemical conversion pathways. Furthermore, to contribute to the development and implementation of sustainable biorefineries, a systematic methodology which combines process modeling and optimization approaches is applied and a comparison of the pathways based on economic and energetic efficiencies is then proposed. The results provide a powerful support for the design of biorefinery systems with improved process economics and reduced environmental impact.
