摘　　要：利用固定床反应器对影响催化燃烧环己酮的工艺条件进行了实验。采用响应面法(RSM)在实验设定条件下,对浓度(A:C)、相对湿度(B:RH)、小时空速(C:GHSV)进行了优化。经RSM优化,得到工艺参数的影响程度为AC>BC>AB>A>C>B,同时获得了环己酮表观降解速率方程:R=89.18-1.89×A-4.18×B+3.62×C-6.12×B×A+5.32×A×C-6.18×B×C-3.22×A^2-19.46×B^2-25.68×C^2。在设定条件范围下,理论预测降解效率为89.6%,实际降解效率为86.5%,结果具有较高的可信度;同时建立了RSM的平面等高线图和3D立体模型,实验方法与结论对实际工程应用具有较高的指导意义。The effects of catalytic combustion conditions on cyclohexanone was studied in a fixed bed reactor. The response surface method（RSM） was used to optimize the concentration of cyclohexanone（A）,relative humidity（B：RH）, and gas hourly space velocity（C：GHSV）, under the conditions of experimental setted. Through RSM optimization, the influence degree of process parameters is AC BC AB A C B. Meanwhile, the equation of apparent degradation rate of cyclohexanone is obtained： R =89.18-1.89 ×A-4.18×B＋3.62×C-6.12×B×A＋5.32×A×C-6.18×B×C-3.22×A^2-19.46× B^2-25.68×C^2. Under the condition of setted, the predicted degradation efficiency is 89.6%, and the actual degradation efficiency is 86.5%, the result has higher reliability. Meanwhile, the plane contour map and 3 D stereo model of RSM are established, the experimental methods and conclusions also give a highly guiding significance for practical engineering application.
