摘要

Recently, using biomass waste to extract levulinic acid (LA) has aroused extensive concerns. This research provides a novel LA preparation system with the use of biomass waste in combination with a coal-fired power plant (CFPP). As a poly-generation system, it not only produces LA, but also generates heat and electricity to self-sustain the energy consumption. Besides, the material balance, thermodynamics and economics of the system are investigated. Findings indicate that the purity of the refined LA can achieve 99.8% and the energy demand per unit mass of LA is 62.14 MW, which is 36.96 MW lower than the same scenario in previous studies. The total energy efficiency and exergy efficiency for the whole process reach 55.16% and 61.36%. Overall, the system will achieve payback of the initial investment in 3.42 years, and the proposal is projected to have a net present value (NPV) of 1.472 203 7×108 USD over its 30-year lifespan.
