Aiming at the problems of low conversion efficiency and target hydrocarbon yield, poor catalyst stability and unsatisfactory process economy in the current catalytic conversion of agricultural and forestry waste biomass such as straw into aviation fuel, this study realized efficient and stable production of bio-aviation fuel matching the component distribution of commercial aviation kerosene from full biomass components through two technical routes: 1) directional hydrothermal depolymerization of hemicellulose and cellulose to produce platform compounds such as furfural and levulinic acid, followed by aldol condensation coupled with hydrodeoxygenation to produce aviation fuel-range alkanes; 2) coupled technology of activating, degrading and hydro-upgrading lignin from hydrothermal depolymerization residues to efficiently produce aromatics and cycloalkanes. The key technologies developed in Projects 1-3, including directional hydrothermal depolymerization of biomass, product carbon chain regulation and hydrogenation catalysis, catalytic conversion of lignin to produce aromatics, cycloalkanes and functional materials, were integrated. Each technical unit was tested and verified on the existing 100-ton-scale demonstration project, and all technical units were connected. Then a 1,000-ton-scale demonstration project was designed and built, followed by commissioning and optimized operation. On this basis, the quality control rules of bio-aviation fuel in core links such as production, storage and transportation, and blending were investigated, and the quality control technology for bio-aviation fuel was established. The results obtained from the operation and verification of the 1,000-ton-scale demonstration project can feed back to guide Projects 1-3, so as to optimize the technical system for efficient production of aviation fuel from full biomass components. The performance indicators of the bio-aviation fuel produced in this dataset meet the ASTM-D7566 standard, which can provide support for the smooth conduct of the aviation engine applicability research of bio-aviation fuel in Project 5. Various important parameters accumulated from the operation and verification of the demonstration project can provide data support for the life cycle assessment in Project 5. The dataset mainly includes: 1,000-ton-scale process package for cellulosic bio-aviation fuel production technology, 1,000-ton-scale demonstration project for producing bio-aviation fuel from cellulosic biomass, performance of bio-aviation fuel produced by the 1,000-ton-scale demonstration project, standardized research reports or procedures for aqueous-phase catalytic conversion of cellulosic biomass to produce bio-aviation fuel, quality control methods for cellulosic bio-aviation fuel production processes, and technical recommendation reports for cellulosic bio-aviation fuel product specifications.
