    • In the fluid catalytic cracking process, improved adaptive behavior of the catalyst section with the regenerator operating in the complete CO-burning mode is achieved by including within the regenerator, as an element of control, variable recycle of regenerated to spent catalyst. In response to excursions of the regenerated catalyst temperature, such as would be caused by change of feedstock, the recycle ratio is altered in a direction to restore the temperature to a predetermined value. The improved control system extends the useful control range, and it also diminishes counterproductive changes in severity induced by disturbances such as change of feedstock quality.
    • 在流化催化裂化过程中,通过在再生器内包含作为对照元素的可再循环再生到废催化剂来实现具有以完全CO燃烧模式操作的再生器的催化剂部分的改进的适应行为。 响应于再生催化剂温度的偏移,例如由原料变化引起的再循环比例,在使温度恢复到预定值的方向上改变再循环比。 改进的控制系统延伸了有用的控制范围,并且还减少了干扰引起的严重性的反作用变化,例如原料质量的变化。

    • An improved catalytic process wherein trace amounts of a metal of period 5 and 6 of Group VIII or rhenium is added to the total catalyst inventory for cracking of gas oil is disclosed. With this improved process, the yield of gasoline, fuel oil, total cracked products, or predetermined combinations thereof, is maximized for the fluid catalytic cracking of any predetermined feed, usually a gas oil. The process employs a kinetic predictive or a correlative model of the cracking process to identify proper operating conditions, including CO.sub.2 /CO ratio in the effluent from the regenerator, and also requires control of the metal activity to achieve optimal conversion of CO to CO.sub.2 in the regenerator.Also disclosed is an improved method for control of a fluid catalytic process wherein the cracking catalyst comprises trace amounts of a metal selected from the group Pt, Pd, Rh, Ru, Ir, Os and Re.
    • 公开了一种改进的催化方法,其中将痕量的VIII族或铼的第5和6周期的金属加入到用于瓦斯油裂化的总催化剂库存中。 通过这种改进的方法,对于任何预定进料(通常为瓦斯油)的流化催化裂化,汽油,燃料油,总裂化产物或其预定组合的产率最大化。 该过程采用裂解过程的动力学预测或相关模型来识别合适的操作条件,包括来自再生器的流出物中的CO 2 / CO比,并且还需要控制金属活性以实现CO在CO 2中的最佳转化 再生器。 还公开了用于控制流体催化方法的改进方法,其中裂化催化剂包含痕量的选自Pt,Pd,Rh,Ru,Ir,Os和Re的金属。

    • In the fluid catalytic cracking process, improved adaptive behavior of the catalyst section with the regenerator operating in the complete CO-burning mode is achieved by including, as elements of control, variable preheat of the oil feed and variable recycle of regenerated catalyst to spent catalyst. In response to excursions of the regenerated catalyst temperature, such as would be caused by change of feedstock, the oil preheat temperature and recycle ratio are altered in a direction to restore the regenerated catalyst temperature to a predetermined value. The improved control system extends the useful control range, and it also diminishes counterproductive changes in severity induced by disturbances such as change of feedstock quality.
