📄 Abstract（原文）
Medium-density fiberboard (MDF) sludge is a pasty byproduct of the wood manufacturing industry generated during washing or filtration processes and poses significant environmental challenges. This study investigates the valorization of this material through catalytic sorption-enhanced steam gasification (SESG) in a fixed-bed reactor, integrating catalytic gasification with in situ CO 2 capture to produce hydrogen-rich gas. The effects of key operating parameters, including weight hourly space velocity (WHSV) (0.5–2.7 h -1 ), temperature (600 °C–650 °C), and steam-to-carbon (S/C) ratio (1.2–14 × stoichiometric), were systematically evaluated. Temperature strongly influenced gasification performance and CO 2 capture efficiency, with 650 °C identified as the optimal condition, yielding up to 88.9 vol% H 2 . Variations in WHSV had a limited effect on hydrogen yield, indicating stable process performance across the investigated range and suggesting the potential to reduce reactor volumes without compromising conversion. H 2 yield increased with steam addition, reaching a maximum of 55.4% and an H 2 purity of 84.7 vol% at an S/C ratio of 8 × stoichiometric. Further increases in steam resulted in lower efficiency, attributed to reduced CO 2 capture due to shorter residence times and dilution effects. While elevated steam demand may introduce energy penalties, the results demonstrate that catalytic SESG is an effective route for hydrogen production from industrial waste. Under the identified optimal conditions (650 °C, S/C = 8 × stoichiometric, WHSV = 0.6 h -1 ), stable performance was achieved despite the heterogeneous nature of MDF sludge, highlighting its viability as a feedstock for low-carbon hydrogen production.
