应用前置烧焦罐式高效再生器催化裂化装置动态机理数学模型及其Ｗｉｎｄｏｗｓ仿真软件平台ＨＥＲＳ，在考察了新鲜原料残炭值、密度、ＡＳＴＭ馏程等单个性质对装置生产操作过程中动态响应和定常态特性的影响后，考察了原料变重（残炭值、密度和沸点均增高）对生产操作的影响。单个性质变化时，只控制催化剂藏量，产品分布变化较小，而再生部分各变量变化较大。３个性质综合变化时，藏量、压力和反应温度全闭环控制，产品分布和再生部分各变量的动态和定常态变化幅度都比只控制催化剂藏量时的大得多
In this paper, the mathematical model of the dynamic mechanism of FCCU high-efficiency regenerator catalytic cracking unit and the Windows simulation software platform HERS were used to investigate the dynamic response of the single raw material such as carbon residue, density and ASTM distillation range during the operation of the unit And the influence of the steady state characteristics, the effects of the raw material weight gain (carbon residue, density and boiling point increase) on the production operation were investigated. When a single property changes, only the amount of the catalyst is controlled, the product distribution changes little, and the variation of the regenerative part varies greatly. When the three properties are comprehensively changed, the reserves, pressures and reaction temperatures are fully closed-loop controlled. The dynamic and steady-state changes of all the variables in the product distribution and regeneration are much larger than those when only the amount of catalyst is controlled
