Unified, curated dataset of biomass hydrothermal treatment/liquefaction experiments for lignocellulosic and lignin-rich biomass

This dataset provides a unified, curated collection of experimental results on the hydrothermal conversion of lignocellulosic and lignin-rich biomass, including hydrothermal treatment (HTT), hydrothermal liquefaction (HTL), and related process variants. The database covers diverse biomass feedstocks, reactor configurations, solvents, catalysts, temperatures, residence times, and operating conditions, with all records normalized to consistent units and yield bases.
