| 摘 要： | 以长庆减压渣油及其胶质亚组分为原料,利用热解-气相色谱质谱联用仪对其在不同条件下热解的产物进行分析,考察反应温度和升温速率对减压渣油热解的影响。结果表明:随着反应温度升高,热解产物中低碳烯烃含量增加,汽柴油馏分含量先增加后减小,在700℃时达到峰值;升温速率为1℃ms时,汽柴油馏分含量最高;芳碳率越大、缩合程度越高的重胶质裂解能力越差。

| Abstract: | The Changqing vacuum residue and resin subfractions were studied by using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) to test the effect of reaction temperature and heating rate on VR pyrolysis. The results showed that as the pyrolysis temperature increased, the yields of light olefins in the pyrolysis product rose gradually, whereas the yields of gasoline and diesel fractions first increased and then decreased with a maximum value at 700oC; when the heating rate is 1℃/ms, the yield of gasoline and diesel reached maximum. The pyrolysis of resins subfractions showed that the higher the aromaticity and the higher the condensation degree, the worse the pyrolysis ability of the resins. |
