Corn cob (CC) and waste cooking oil (WCO) were co-pyrolyzed in a fixed bed. The effects of various temperatures of 500 °C, 550 °C, 600 °C and CC/WCO mass ratios of 1:0, 1:0.1, 1:0.5, 1:1 and 0:1 were investigated, respectively. Results show that co-pyrolysis of CC/WCO produce more liquid and less bio-char than pyrolysis of CC individually. Bio-oil and bio-char yields were found to be largely dependent on temperature and CC/WCO ratios. GC/MS of bio-oil show it consists of different classes and amounts of organic compounds other than that from CC pyrolysis. Temperature of 550 °C and CC/WCO ratio of 1:1 seem to be the optimum considering high bio-oil yields (68.6 wt.%) and good bio-oil properties (HHV of 32.78 MJ/kg). In this case, bio-char of 24.96 MJ/kg appears attractive as a renewable source, while gas with LHV of 16.06 MJ/Nm(3) can be directly used in boilers as fuel.
玉米芯 (CC) 和废食用油 (WCO) 在固定床上共热解。分别考察了不同温度（500°C、550°C、600°C）和 CC/WCO 质量比（1:0、1:0.1、1:0.5、1:1 和 0:1）的影响。结果表明，CC/WCO 的共热解比单独热解 CC 产生更多的液体和更少的生物炭。生物油和生物炭的产率主要取决于温度和 CC/WCO 比。生物油的 GC/MS 分析表明，它由不同种类和数量的有机化合物组成，而不是来自 CC 热解的有机化合物。考虑到较高的生物油产率（68.6wt.%）和较好的生物油性能（HHV 为 32.78MJ/kg），550°C 的温度和 CC/WCO 比为 1:1 似乎是最佳选择。在这种情况下，24.96MJ/kg 的生物炭作为可再生能源具有吸引力，而热值为 16.06MJ/Nm(3) 的气体可以直接用作锅炉燃料。
