リグニンを水熱液化（HTL）で含酸素芳香族へ変換し、フェノール樹脂前駆体（シナリオ1）とSAF混合基材（シナリオ2）を製造する2経路を、TEAとLCAで評価した。シナリオ1は固形副産物の炭素貯留クレジットにより純負のGWPを達成し、パルプ廃棄物利用で−2.30 kg CO2 eqと最小。シナリオ2のSAFは5.9 g CO2 eq/MJで、従来ジェット燃料83.8 gを大幅に下回る。MSPは各々3.32、8.03ドル/kgで、米IRA税額控除適用で7.52ドル/kgに低減する。

This study models lignin hydrothermal liquefaction (HTL) into oxygenated aromatics for phenolic resin precursors (Scenario 1) and SAF blendstock (Scenario 2), using TEA and LCA. Scenario 1 achieves net-negative GWP across lignin sources, reaching −2.30 kg CO2 eq with pulp waste. Scenario 2 SAF shows 5.9 g CO2 eq/MJ, far below the 83.8 g conventional jet fuel baseline. MSPs are $3.32/kg and $8.03/kg, falling to $7.52/kg with US IRA credits.

📄 Abstract（原文）
Abstract Hydrothermal liquefaction (HTL) is a promising approach that converts lignin into oxygenated aromatics, which serve as precursors of phenolic resins and sustainable aviation fuel (SAF) blendstock. However, its rigorous modeling and evaluation remain underexplored due to complexities in reaction mechanisms. Here, we introduce a model-compound-based process modeling framework and evaluate two HTL-based lignin conversion processes using techno-economic analysis (TEA) and life cycle assessment (LCA). Scenario 1 considers oxygenated aromatics as a precursor for phenolic resins, while Scenario 2 upgrades them to SAF blendstock via hydrotreating. Our LCA reveals that Scenario 1 achieves a net negative global warming potential (GWP) across various lignin sources, driven by carbon storage credits from solid co-products. Among the lignin species, using pulp waste offers the lowest GWP at −2.30 kg CO2 eq. In Scenario 2, the SAF blendstock is produced at a GWP of 5.9 g CO2 eq/MJ, with additional contributions from green hydrogen via alkaline electrolysis (AEL), while values across practical lignin sources range from −28.3 to 41.9 g CO2 eq/MJ. Solid co-product credits enable the blendstock to significantly outperform the 83.8 g CO2 eq/MJ baseline for conventional jet fuel. Furthermore, implementing this technology in highly decarbonized grids is essential for maximizing climate benefits. Concurrently, TEA shows that the minimum selling price (MSP) is $3.32/kg and $8.03/kg for producing resin precursor (Scenario 1) and SAF blendstock (Scenario 2), respectively. Applying US IRA tax credits ($1.53/gal) further reduces the latter to $7.52/kg.
