将一种基于催化裂化反应机理的动力学模型应用于重油催化裂化过程,实验确立了几种典型的催化裂化催化剂的反应速率常数。模拟实验的结果表明,通过实验确定的各反应速率常数不仅可以对重油催化裂化产品的产率分布进行模拟和预测,而且可以较为准确地对产品族组成进行模拟和预测。该模型包含十四个集总共24个反应速率常数,易于在提升管反应器上应用。
A kinetic model based on the catalytic cracking reaction mechanism was applied to the heavy oil catalytic cracking process. The reaction rate constants of several typical catalytic cracking catalysts were experimentally established. The simulation results show that the reaction rate constants determined by experiments can not only simulate and predict the yield distribution of heavy oil catalytic cracking products, but also simulate and predict the product family composition more accurately. The model contains a total of 24 reaction set of fourteen reaction rate constants, easy to apply in the riser reactor.
