Energy consumption for production of jet fuel precursors from cellulosic biomass by hydrothermal method

Biomass for production of alternative jet fuel has a very important impact on global carbon reduction and the control of greenhouse gas emissions. Wide sources and large annual output of cellulosic biomass have become its significant advantages as a biomass raw material to produce aviation alternative fuels. Based on the latest research results of cellulosic biomass, the process parameters and yield of the key process units for the production of jet fuel precursor (furfural (FF), 5-hydroxymethylfurfural (5-HMF) and levulinic acid (LA)) from cellulosic biomass were studied in depth in this paper. Through Aspen Plus process simulation, the material flow and energy flow of FF and LA, FF and 5-HMF were studied and compared. The influence of different process parameters on the yield was obtained, and energy consumption analysis of the advantageous process flow was carried out, which provides a theoretical basis for increasing the yield of platform compounds and reducing energy consumption of production of alternative jet fuel from biomass.
