Catalytic pyrolysis was used to generate gasoline-compatible fuel from peanut oil soap stock (PSS), a high free fatty acid feedstock, using a fixed-bed reactor at temperatures between 450 and 550°C with a zeolite catalyst (HZSM-5). PSS fed at 81 gh(-1) along with 100 mL min(-1) inert gas was passed across a 15 g catalyst bed (WHSV=5.4h(-1), gas phase residence time=34s). Results indicate that fuel properties of PSS including viscosity, heating value, and O:C ratio were improved significantly. For PSS processed at 500°C, viscosity was reduced from 59.6 to 0.9 mm(2)s(-1), heating value was increased from 35.8 to 39.3 MJL(-1), and the O:C ratio was reduced from 0.07 to 0.02. Aromatic gasoline components (e.g., BTEX), were formed in concentrations as high as 94% (v/v) in catalytically-cracked PSS with yields ranging from 22% to 35% (v/v of PSS feed).
采用固定床反应器，以沸石催化剂（HZSM-5）为催化剂，在 450-550°C 的温度范围内，从高游离脂肪酸原料——花生油皂脚（PSS）中催化热解生成与汽油相兼容的燃料。以 81gh(-1)的速度进料 PSS，并以 100mLmin(-1)的惰性气体通过 15g 催化剂床(WHSV=5.4h(-1)，气相停留时间=34s)。结果表明，PSS 的燃料特性，包括粘度、热值和 O:C 比都得到了显著改善。对于在 500°C 下处理的 PSS，粘度从 59.6 降低到 0.9mm(2)s(-1)，热值从 35.8 增加到 39.3MJL(-1)，O:C 比从 0.07 降低到 0.02。催化裂化 PSS 中的芳烃汽油成分（例如 BTEX）的浓度高达 94%（v/v），产率为 22%-35%（PSS 进料的 v/v）。
