AI Technical Summary
Technical Problem
Existing fixed-bed reactor temperature profile control technologies fail to effectively utilize information about changes in feed composition, making it difficult to precisely adjust reactor temperature, which affects conversion rate, product yield, and quality.
Method used
By employing the method of interstage model error input and combining it with the model predictive control (MPC) algorithm, the reactor temperature curve is automatically controlled to compensate for changes in feed composition by adjusting the feed temperature and interstage cooling.
Benefits of technology
It improves the efficiency of reactor operation, enhances conversion rate, product yield and quality, and enables dynamic response to changes in feed composition and precise temperature control.

Abstract
公开了用于改进具有至少三个固定床、放热反应和级间冷却的反应器中的温度曲线控制的系统、服务器和方法。跨第一床的温度差的模型被开发并且其误差被用于推断不可测量的进料成分扰动，这些不可测量的进料成分扰动在下游固定床的控制中被使用以用于对不可测量的进料成分改变的更快响应以及对整个反应器的温度曲线的改进控制。第一床模型误差然后被用作预测反应器温度曲线的总体模型的输入，这提供下游床中的反应的提前通知，并且使得能够实现对进料成分改变的高效调整和补偿。模型预测控制(MPC)算法被应用以调整床中间冷却和第一床进料温度，使得可以更精确地控制反应器温度曲线。
