颗粒动力学模型的建立

催化裂化提升管反应器内原料油和催化剂颗粒间存在强烈地传质、传热和动量传递，同时进行着复杂地裂化反应，描述流化状态的催化剂颗粒流动特征非常困难，而它对裂化反应的影响又至关重要，因此人颗粒速度分布函数出发，推导出催化剂颗粒相流动方程结合油气湍流流动、耦合集总动力学模型，得到了催化裂化提升管反应器数学模型，为进步研究提升管内的反应特征和反应历程提供了有力手段。

Development of Kinetic Model of Granular Flow

There exists intensive mass-transfer, heat-transfer and momentum-transfer between catalysts and cracking reaction synchronously. It is very hard to describe the catalysts' hydrodynamics. This article deduced the hydrodynamic equation from the function of velocity distribution. An advanced mathematical model is acquired by coupling the lumping model. The model should be an effective way to further research the reactive characteristics and reactive course in FCC riser.
