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

This Version 0 record contains an earlier literature-derived export of the unified biomass hydrothermal treatment and liquefaction dataset. The deposited CSV contains 3,543 records and 103 columns covering source metadata, feedstock identity and composition, operating conditions, process context, product yields, condensed-phase properties, derived descriptors, and quality-control fields. The record is retained for provenance and citation history. It has been superseded by Version 1.0.0, DOI: 10.22000/8bnbhqccf4aq7kea, which provides the complete 3,693-record publication-facing dataset and should be used for new analyses and reproducibility work.

Data were extracted from scientific publications and institutional research sources, digitized where necessary, and harmonized to a standardized tabular schema. Units, nomenclature, yield bases, and process descriptors were normalized where supported by the source information. Selected values were calculated or imputed where documented in the deposited fields. Source title is provided for every record; DOI/source identifier and more granular Provenance and Ref information are retained where available. Quality-control and method fields support record review and subset construction.

The deposited package contains one primary CSV file, master_dataset.csv, with 3,543 experimental records and 103 columns. The columns cover:

• source and provenance metadata;
• feedstock identity and standardized family labels;
• feedstock elemental and lignocellulosic composition;
• process subtype, reactor, solvent or medium, catalyst, temperature, residence time, pressure, and loading descriptors;
• biocrude/bio-oil, hydrochar/solid-residue, aqueous-phase, and gas yields;
• condensed-phase elemental composition and higher heating values;
• energy and carbon allocation variables;
• calculation, imputation, provenance, and quality-control fields.

This metadata correction describes the content of the deposited Version 0 CSV without modifying the archived data package. The structured related identifier records Version 0 as IsPreviousVersionOf Version 1.0.0. Users should cite this DOI only when referring specifically to the earlier Version 0 export; Version 1.0.0 should be cited for the complete dataset.
