The catalytic pyrolysis of palm kernel shell was investigated in a fluidized bed with zsm-5 and equilibrium FCC (Ecat) catalysts. Catalytic pyrolysis oil yields were remarkably reduced and gas yields were increased due to the higher catalytic reaction of primary volatiles compared to non-catalytic pyrolysis. Char yields were affected by temperature and the pore structure of the catalysts. The pyrolysis oil was characterized by lower H/C and O/C molar ratios due to aromatization and deoxygenation of volatiles by the catalysts. The catalytic pyrolysis oils contained more oxygen and nitrogen and less sulfur than petroleum oils. The oils had a high concentration of nitriles, with a carbon number distribution similar to fatty acids. The catalytic pyrolysis oils featured high nitriles yield with Ecat and high aromatics yield in the light fraction with zsm-5, due to characteristics of the catalyst. The catalytic pyrolysis oils showed potentials as feedstocks for bio-diesel and chemicals.
采用流化床反应器，以 ZSM-5 和平衡流化催化裂化（Ecat）催化剂对棕榈仁壳进行催化热解。与非催化热解相比，由于初级挥发物的催化反应较高，催化热解油的产率显著降低，气体产率增加。由于温度和催化剂的孔结构的影响，炭产率受到影响。由于催化剂对挥发物的芳构化和脱氧作用，热解油的 H/C 和 O/C 摩尔比降低。与石油相比，催化热解油含有更多的氧和氮，硫含量更少。油中含有高浓度的腈，其碳数分布与脂肪酸相似。由于催化剂的特性，Ecat 具有高的腈产率，而 ZSM-5 则在轻馏分中具有高的芳烃产率。催化热解油具有作为生物柴油和化学品原料的潜力。
