This study explores copyrolysis of soybean straw (SS) with hydrogen-rich tire waste (TW) to enhance pyrolytic product quality and reduce pollutant emissions. Addition of TW increased SS biomass conversion from 67.19 to 72.46% and decreased coke/residue formation from 32.81 to 27.54%. The activation energy dropped to 121.84 kJ/mol from 160.73 kJ/mol (as calculated by the Kissinger-Akahira-Sunose method) and 122.78 kJ/mol from 159.76 kJ/mol (as calculated by the Ozawa-Flynn-Wall method). Thermogravimetric analysis coupled with Fourier-transform infrared spectroscopy (TG-FTIR) showed lowered CO, NO, and SO emissions (5.58, 5.72, 3.38) compared to conventional SS pyrolysis (18.38, 11.55, 12.37). Yields of value-added chemicals (phenols, olefins, aromatics) increased (32.38, 22.17, 30.18%) versus conventional SS pyrolysis (23.56, 13.78, 20.36%). Pyrolysis gas chromatography-mass spectrometry (Py/GC-MS) analysis reveals that the addition of TW leads to a decrease in the production of oxygenates and polycyclic aromatic hydrocarbons, reducing their yields to 8.96 and 7.67%, respectively, down from 19.37 and 14.37%. Simultaneously, it enhances the yields of olefins, aromatics, phenols, and aliphatic hydrocarbons to 23.38, 26.78, 26.17, and 25.78%, respectively, compared to 15.37%, 15.29, 18.36, and 17.25%, respectively, in the absence of TW. In summary, copyrolysis of TW with SS improves product quality and reduces pollutant emissions, marking a significant research contribution.
本研究探索了大豆秸秆（SS）与富氢轮胎废料（TW）的共热解，以提高热解产物质量并减少污染物排放。添加TW使SS生物质转化率从67.19%提高到72.46%，并使焦炭/残渣形成量从32.81%降至27.54%。活化能从160.73 kJ/mol降至121.84 kJ/mol（通过基辛格-赤平-ose方法计算），从159.76 kJ/mol降至122.78 kJ/mol（通过小泽-弗林-沃尔方法计算）。热重分析结合傅里叶变换红外光谱（TG-FTIR）显示，与传统SS热解（18.38、11.55、12.37）相比，CO、NO和SO排放量降低（5.58、5.72、3.38）。增值化学品（酚类、烯烃、芳烃）的产率相对于传统SS热解（23.56、13.78、20.36%）有所提高（32.38、22.17、30.18%）。热解气相色谱-质谱（Py/GC-MS）分析表明，添加TW导致含氧化合物和多环芳烃的产量下降，其产率分别从19.37%和14.37%降至8.96%和7.67%。同时，与不添加TW时分别为15.37%、15.29%、18.36%和17.25%相比，它使烯烃、芳烃、酚类和脂肪烃的产率分别提高到23.38%、26.78%、26.17%和25.78%。总之，TW与SS的共热解提高了产物质量并减少了污染物排放，这是一项重要的研究贡献。
