Pilot-scale Evaluation of High-Temperature-Winkler® Gasification using Waste Wood as Feedstock

Short Introductive summary

The substitution of fossil fuels with green energy carriers requires diverse technological pathways to secure renewable carbon sources for industry. Gasification of biogenic residues represents a robust and flexible option, less dependent on electricity market fluctuations than Power-to-X, and enables the production of renewable fuels and platform chemicals. High-Temperature-Winkler® (HTW®) gasification is particularly promising, as it delivers high-quality syngas with minimal fuel pre-treatment. In this study, waste wood from construction and demolition is investigated as a novel feedstock for HTW® gasification. At TU Darmstadt, a 500kWth HTW® pilot plant was operated for more than 100 hours, converting over 8t of pelletized waste wood with oxygen and steam. Systematic variation of the O2/steam ratio revealed strong effects on reactor temperature, syngas yield, and composition. Results demonstrate that higher temperatures improve carbon conversion, reduce tar formation, and enhance syngas quality. This work, conducted within the EU-funded Bio-MeGaFuel project, provides valuable experimental data for scaling HTW® technology with waste wood.
