用共轭算子法分析CO偶联反应的灵敏度

Sensitivity Analysis for CO Coupling Reaction by Use of Adjoint Operators

运用非线性泛函分析方法一共轭算子法,从简化的过程数学模型出发,对CO偶联固定床反应器的灵敏度进行了综合分析.论述了操作参数、动力学参数偏离标称值时转化率和床层温度的变化情况,确定了不同参数对反应性能指标的影响顺序.为进一步研究该反应体系的优化控制及反应机理识别提供了有效的工具.

By use of the nonlinear functional analysis approach-the method of adjoint operators, the sensitivity analysis for CO coupling is comprehensively carried out in order to reveal important parameters in the research of reaction mechanism and in the design and operation of a tubular reac tor for synthesis of diethyl oxalate on the basis of the simplified mathematical reactor modei. The influence of operating and kinetic parameter variations from their nominal values on conversion and reactor bed temperature profile is cliscussed. The results provide an effective approach to the opti mal control for existed industrial plants and the identification of reaction mechanism.
