In this study, catalytic fast co-pyrolysis (co-CFP) of corn stalk and food waste (FW) was carried out to produce aromatics using quantitative pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and ZSM-5 zeolite in the hydrogen form was employed as the catalyst. Co-CFP temperature and a parameter called hydrogen to carbon effective ratio (H/C(eff) ratio) were examined for their effects on the relative content of aromatics. Experimental results showed that co-CFP temperature of 600 °C was optimal for the formation of aromatics and other organic pyrolysis products. Besides, H/C(eff) ratio had an important influence on product distribution. The yield of total organic pyrolysis products and relative content of aromatics increased non-linearly with increasing H/C(eff) ratio. There was an apparent synergistic effect between corn stalk and FW during co-CFP process, which promoted the production of aromatics significantly. Co-CFP of biomass and FW was an effective method to produce aromatics and other petrochemicals.
本研究采用定量热解气相色谱/质谱联用（Py-GC/MS）技术，以氢型 ZSM-5 沸石为催化剂，对玉米秸秆和食品废物（FW）进行催化快速共热解（co-CFP），以生产芳烃。考察了 co-CFP 温度和一个称为氢碳有效比（H/C(eff) ratio）的参数对芳烃相对含量的影响。实验结果表明，600°C 的 co-CFP 温度有利于芳烃和其他有机热解产物的形成。此外，H/C(eff) 比对产物分布有重要影响。随着 H/C(eff) 比的增加，总有机热解产物的产率和芳烃的相对含量呈非线性增加。在 co-CFP 过程中，玉米秸秆和 FW 之间存在明显的协同作用，显著促进了芳烃的生成。生物质和 FW 的 co-CFP 是生产芳烃和其他石化产品的有效方法。
