In this work, catalytic cracking of biomass waste oil fractions separated from food waste leachate was performed using microporous catalysts, such as HY, HZSM-5 and mesoporous Al-MCM-48. The experiments were carried out using pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) to allow the direct analysis of the pyrolytic products. Most acidic components, especially oleic acid, contained in the food waste oil fractions were converted to valuable products, such as oxygenates, hydrocarbons and aromatics. High yields of hydrocarbons within the gasoline-range were obtained when microporous catalysts were used; whereas, the use of Al-MCM-48, which exhibits relatively weak acidity, resulted in high yields of oxygenated and diesel-range hydrocarbons. The HZSM-5 catalyst produced a higher amount of valuable mono aromatics due to its strong acidity and shape selectivity. Especially, the addition of gallium (Ga) to HZSM-5 significantly increased the aromatics content.
在这项工作中，使用微孔催化剂（如 HY、HZSM-5 和介孔 Al-MCM-48）对从餐厨垃圾渗滤液中分离出的生物质废油馏分进行催化裂化。使用热解气相色谱/质谱联用仪（Py-GC/MS）进行实验，可直接分析热解产物。废油馏分中含有的大多数酸性成分，特别是油酸，转化为有价值的产品，如含氧化合物、烃类和芳烃。使用微孔催化剂可获得高收率的汽油范围内的烃类；而使用 Al-MCM-48 则由于其较弱的酸性而导致含氧和柴油范围内的烃类收率较高。由于其强酸性和形状选择性，HZSM-5 催化剂产生了更多有价值的单芳烃。特别是，将镓 (Ga) 添加到 HZSM-5 中显著增加了芳烃含量。
