【摘要】 在升温速率为2.22K/min～12.34K/min的范围内考察了抚顺页岩的热分解过程。按照一级反应动力学模型,分别采用积分法和微分法求算了不同升温速率下的热分解动力学参数,结果表明:在主要热解阶段,抚顺页岩的表观活化能波动于35.1kcal/mol(积分法)及38.7kcal/mol(微分法)上下,升温速率对动力学参数未见有明显的规律性影响,但升温速率的增加使得转化率曲线及热解产物挥发速率曲线出现显著的变化,本文扼要地讨论了引起转化率曲线及挥发速率曲线变化的原因。更多还原

【Abstract】 Pyrolysis of Fushun oil shale at different heat-up rates 2.22-12.34K/min has been investigated.According to the kinetics model of first-order reaction, the kinetics parameters of pyrolysis of Fushun oil shale at different heat-up rates have been estimated by integral and differential methods respectively. The results show that the apparent activation energy during the major period of pyrolysis is in the range of 35.lkcal/mol (integral method) and 38.7kcal/ mol (differential method).No obvious effect of variation of heat-up rate on kinetic parameters was discovered.However, an increase of heat-up rate resu-lted in clear variation of the shape of conversion curves and volatilization rate curves of pyrolysis products.The cause of the variation has been discu-ssed briefly.更多还原
