This study explores the catalytic co-pyrolysis of cabbage waste (CW) and tire waste (TW) to enhance the yield and quality of bio-oil and syngas. Although CW is produced in large quantities from global cabbage cultivation, its lower hydrogen content limits its utility for fuel and chemical production. The co-pyrolysis process, utilizing char as a catalyst, presents a cost-effective approach to optimize product outputs by promoting the reforming of volatiles during thermal decomposition. Thermogravimetric-infrared spectrometry (TG-FTIR) and a dual-stage fixed bed reactor were employed to assess thermal behavior, the release of evolved gases and product composition. Results demonstrated that catalyst-assisted co-pyrolysis with char reduced non-condensable emissions to 33.45% and increased condensable products to 66.57%, compared to 39.57% and 60.46% for co-pyrolysis alone, and 49.23% and 50.77% for CW pyrolysis. Furthermore, char-mediated volatile reforming significantly decreased the oxygenated fraction to 6.7% from 13.6% in co-pyrolysis and 22.5% in CW pyrolysis and greatly increased phenolic compounds and aromatics to 28.3% and 31.7% from 22.3% and 27.8% for co-pyrolysis, 17.9% and 21.7% for biomass pyrolysis, respectively. This research highlights the potential of integrating biomass and waste materials to promote sustainable energy solutions through enhanced resource utilization and diminished environmental impact.
本研究探索了甘蓝废弃物（CW）与轮胎废弃物（TW）的催化共热解，以提高生物油和合成气的产量及质量。尽管全球甘蓝种植产生大量的CW，但其较低的氢含量限制了其在燃料和化学品生产中的应用。利用焦炭作为催化剂的共热解过程，通过促进热分解过程中挥发物的重整，提供了一种经济高效的方法来优化产品产出。采用热重-红外光谱法（TG-FTIR）和双阶段固定床反应器来评估热行为、逸出气体的释放及产物组成。结果表明，与单独共热解时的39.57%和60.46%以及CW热解时的49.23%和50.77%相比，用焦炭进行催化剂辅助共热解将不可冷凝排放物减少至33.45%，并将可冷凝产物增加至66.57%。此外，焦炭介导的挥发物重整显著降低了含氧馏分，从共热解时的13.6%和CW热解时的22.5%降至6.7%，并大幅增加了酚类化合物和芳烃，从共热解时的22.3%和27.8%、生物质热解时的17.9%和21.7%分别增至28.3%和31.7%。本研究突出了整合生物质与废料以通过提高资源利用率和减少环境影响来促进可持续能源解决方案的潜力。
