本研究は、プラスチック含有廃棄物由来燃料を1MWthパイロット規模で化学ループ燃焼(CLC)および化学ループガス化(CLG)に供し、イルメナイトを酸素キャリアとして性能を評価した。CLCではCO2回収率は平均95%と高いが、燃料炭素の約3分の1しかCO2に転換されず、酸素要求量は約60%に達した。CLGではオフガスに燃料エネルギーの約70%が保持されるが、COとH2は10%未満で、メタンや芳香族が主体であり、従来型合成ガスの収率は低かった。両経路とも更なる開発が必要であり、経路の選択は政策・市場枠組みに依存する。
English
This study evaluates chemical looping combustion (CLC) and gasification (CLG) of a plastic-rich waste-derived fuel at 1 MWth pilot scale using ilmenite as oxygen carrier. CLC achieved high CO2 capture (~95%) but only about one-third of fuel carbon reached CO2, with oxygen demand near 60%. CLG retained ~70% of fuel energy in off-gas, but less than 10% was CO and H2, with methane and aromatics dominating, indicating low syngas yield. Both pathways require further development, with route preferability depending on policy and market frameworks.

📄 Abstract(原文)
Waste disposal remains a contributor to greenhouse gas emissions, while waste-to-energy with carbon capture or gasification-based carbon recycling offers potential routes to carbon neutrality or even net carbon removal. Chemical looping can support both pathways: either through inherent CO 2 capture as a combustion process (CLC), or through generation of a nitrogen-free syngas as a gasification process (CLG). However, practical evaluation with real waste materials has remained limited to small scale. This study examines a plastic-rich waste-derived fuel at 1 MW th pilot scale with ilmenite as oxygen carrier, assessed from both CLC and CLG perspectives. Detailed analysis of the fuel-reactor off-gas, including heavy hydrocarbons, revealed only partial oxidation of volatiles and a consequently high residual combustible content with opposite implications for the two pathways. From a CLC perspective, while carbon capture related to waste-derived fuel was high, averaging 95 %, only about one third of the fuel carbon reached CO 2 , giving an oxygen demand near 60 %. However, comparison across pilots suggests that this is consistent with unfavorable operating conditions without a resolvable effect of scale itself. From a CLG perspective, the corresponding ∼70 % of fuel energy retained in the off-gas is favorable. However, less than 10 % was present as CO and H 2 , while methane, light olefins, and aromatics dominated, indicating a low yield of conventional syngas that appears fuel-intrinsic relative to biomass tested in the same plant. These results show that both pathways require further development, with route preferability linked to the policy and market framework.
