The mathematical model of catalytic reforming was built in this pape匚 And the model was resolved with the method of sequence module. Then the project was completed with the current steady state simulation software. The result of the simulation describes the system very well. At last, we got a (raining simulator which can be used io (rain the workers.Furthermore, for the simulation of the catalytic reforming reactor is always the emphasis of the whole catalytic reforming simulation, so the catalytic reforming reactor steady state simulation and dynamic simulation were withal discussed respectively in the dissertation. The mathematical model established the foundation of the catalytic reforming reactor further study.According to the guiding principles of lumping theory and based on the study of reaction mechanisms, a new model with sixteen lumped components was proposed for catalytic reforming. It can also help to guide the dynamic simulation for this process.-in-Because steady state model is very important to impolder the dynamic simulation, the steady state simulation of catalytic refonning reactor with seventeen lumped components was established in this paper. It describes the reactor correctly.In conclusion, the dynamic simulation of catalytic reforming and the discussion of the catalytic reforming reactor simulation were demonstrated in this dissertation. Remarkablely, the lumping theory provides a new way to study the catalytic reforming simulation and it will make the dynamic simulation more and more accurate with the lumped components rather subsection.KEY WORDS: dynamic simulation, steady state simulation, catalytic reforming, reactor, lumping, mathematical modelABSTRACT131. 1 31. 1.1 31. 1.2 41.2 61.2.1 61. 2. 2 61. 2. 3 81.2.4 91.2.5 111.2.5 111. 3 121.4 131.4.1 131. 4. 2 141. 4. 3 141.5 141. 6 151.6.1 161. 6. 2 171. 6. 3 181.7 1844333333333321 165(JI555432i81432i423943394339432222222222222888888765432144321NJ2522cJ7$43201U1U1CHU101U1U154322221 3 2i5 cn95符号说明符号意义说明单位aabcdCliI叫2JAS1GG G a GA B C Dmol/(ms h)CpkJ/ kg KG：kJ/ kmolEkj/molEfJJ/molF,1kmol/hFijJFojJG G。kg/hH、Ikj/kgJkj/mol-#-kj/moliPkkkm nk、kAc如ijKKcLoMjjnPN5N6NP/iPoPQ,QyJS1kgMPaMPaMPakj/h-#-kj/h-#-巧RRom3/Skg/ m3 hkg/ ms hmol/52m-#-#-505152-#-#-SKKJcmVmolm5TTjUV巧% 乃必-#-#-Veal/-#-bkg/m5p-#-32197040-# -第一章流程模拟系统概述1.1化工流程模拟基本概念及发展史1.1.1化工流程模拟基本概念40PID-#-1121.1.2化工流程模拟技术发展史11111958FORTRAN CFORTRANALGOL COBOL131979PROCESS1976ASPENFORTRAN-#-Flow TranASPENASPEN PLUSPROCESSCoadeMicro CHESS1.2化工流程模拟系统1.2.1通用化工流程模拟系统FORTRAN C C+19581.2.2专用化工流程模拟系统-#-1ASPEN-#-1.2.3稳态流程模拟1958FLEXI
