中文摘要：
在固定床反应器中，研究玉米芯单独热解与玉米芯／废油脂共热解反应，比较二者三相产物的异同。与单独热解相比，共热解工况下液体产物产率相对较高，气体及固体产物产率相对较低；共热解工况下液体产物含氧量更低，热值更高。二者液体产物的GC-MS及GC-FID分析结果表明：共热解含氧有机物（如苯酚、呋喃、乙酸等）低于单独热解，而烃类有机物（如甲苯、二甲苯等）高于单独热解；气体产物分析表明：共热解CH4、C2H4、C2H6、C3H6、C3H8的浓度均高于单独热解，CO浓度变化不大，CO2浓度相对减少。液相与气相产物品质的提高主要是由于废油脂的添加可增加热解原料的有效氢碳比，这为利用废油脂提供了新的思路。
英文摘要：
Experiments on c reactor. Three phase products o-pyrolysis of corn-cob and waste cooking-oil were conducted in a lab-scale fixed-bed were compared with that of single pyrolysis of corn-cob, and the results showed that yields of liquid product increases with decreasing yields of solid and gas products, and the HHV of liquis product raises with the reduction of oxygen ratio. Compared their liquid products in GC-MS and GC-FID, the results showed that organic compounds of co-pyrolysis contained lower oxygenated compounds （e.g. phenols, furans, acids） and higher hydrocarbons （e.g. toluene, dimethyl benzene） than that of single pyrolysis. The quality of co-pyrolysis gas is upgraded and yields of CH4, C2H4, C2H6, C3H6, C3Hs were higher than single pyrolysis. No obvious change of CO was observed, while yields of CO2 decreased. The upgrading qualities of pyrolysis products may be due to the increased Ceff/H ratio of waste cooking-oil, meanwhile indicating a possible way of using waste cooking-oil.
