Considering the importance of bio-wastes thermo-chemical conversion to fuel and platform molecules, three types of zeolites (ZSM-5, Beta and Y) were tested as heterogeneous catalysts. Peanut shell is a high volume agricultural waste. Its pyrolysis mediated by different catalysts was evaluated. The effect of the zeolite matrix over the bio-oil yield and products selectivities was carefully considered. Fresh and used materials were widely characterized by XRD, FTIR, ICP and BET techniques. Pyrolysis reactions were done at 500 °C under N₂ flow. The use of zeolites in biomass pyrolysis showed interesting results in terms of bio-oil composition. When H-ZSM-5 catalyst was employed, higher bio-oil yields and greater concentration of aromatic hydrocarbons and furans were obtained.

考虑到生物废物热化学转化为燃料和平台分子的重要性，测试了三种沸石（ZSM-5，Beta和Y）作为多相催化剂。花生壳是一种大量的农业废弃物。评价了其在不同催化剂作用下的热解。仔细考虑了沸石基质对生物油收率和产物选择性的影响。XRD，FTIR，ICP和BET技术对新鲜和用过的材料进行了广泛表征。在N ₂流下于500°C进行热解反应。在生物油热解中使用沸石显示出有趣的结果，涉及生物油的组成。当使用H-ZSM-5催化剂时，获得了更高的生物油产率以及更高浓度的芳族烃和呋喃。
