报告题目：Biorefinery Multi-scale Modelling — From fundamental to application
报告简介：A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, heat, and value-added chemicals from biomass. It is a promising alternative to replace petroleum fuel as a sustainable energy supplier. So far, conversion efficiency and cost are still big challenges to build a real biorefinery factory. Experimentally constructing and operating large-scale biofuel plants has experienced tremendous financial difficulties. This presentation will introduce an advanced tool - multi-scale modeling to explore fundamental issues such as essential mechanism and application problems such as new technology and process assessment that can address the aforementioned challenges. Multi-scale phenomena occur in a broad range of scientific and engineering areas including biorefinery. In recent years multiscale modeling and computation have been applied in many areas including biological system, material science, fluid mechanics, chemistry, and chemical engineering. It is widely recognized that multiscale techniques will become an essential part of science and engineering. The fundamental study is starting from cell-scale that is a basic unit in a fermentation process. In-house software should be developed to describe new concepts, multi-physics phenomena and essential mechanisms from micro-scale to macro-scale in a biorefinery process. High Performance Computing (HPC) can provide a powerful capacity to solve large-scale numerical equations for the hundreds and thousands of cells’ growth, movement and metabolism etc. The application research also has been conducted to design, scale-up and optimize the bioreactors and biorefinery processes. It is convenient to use a commercial software because its results has been examined and recognized as reliable information for industrial application. As examples, computational fluid dynamics (CFD) was used to understand the flow behavior and biochemical reactions in aerobic and anaerobic fermentation. Process simulation was used to assess the techno-economically feasibility of forest residues – based biorefinery and anaerobic digestion – based biorefinery. The techno-economic analysis (TEA) modeling also helps to direct research activities by examining sensitivities of the prices to process alternatives and research advances.
