20.500.12556/DKUM-84894 Razvoj in implementacija simulacijskega modela reaktorja za Fisher-Tropschevo sintezo za zeleni prehod v AVL CRUISE TM M magistrsko delo Development and implementation of a Fisher-Tropsch synthesis reactor simulation model as a digital technology for green transition in AVL CRUISE TM M V tem magistrskem delu smo se osredotočili na študij in modeliranje visokotemperaturnega Fischer-Tropschevega procesa, s poudarkom na razumevanju procesnih pogojev, vloge katalizatorjev in mehanizmov kemijske reakcije. Fischer-Tropscheva sinteza je kemijski postopek za pretvorbo sinteznega plina, mešanice ogljikovega monoksida in vodika, v ogljikovodike. Osrednji del dela je bil razvoj kinetičnega modela in njegova implementacija v programih Aspen Plus in CRUISETM M. Glavni cilj študije je bil raziskati in primerjati izhodne rezultate obeh programov, opazovati vpliv parametrov, kot so temperatura, sestava vtoka in tlak, na presnovo reaktantov in proizvodnjo produktov, ter proučiti vpliv diskretizacije v programu CRUISETM M. Rezultati analize kažejo razlike v izračunanih vrednostih med obema programoma. V programu Aspen Plus smo opazili večjo presnovo reaktantov oziroma večji masni pretok nasičenih in nenasičenih ogljikovodikov. V obeh simulacijah smo med produkti opazili največji masni delež pentana. V nadaljevanju smo se posvetili primerjavi rezultatov z literaturo, s posebnim poudarkom na analizi parametra α (verjetnost rasti verige), ki vpliva na distribucijo ogljikovodikov na izhodu iz reaktorja. V študiji smo preučevali tudi vpliv različnih faktorjev, kot so temperatura, sestava vtoka in tlak na rezultate reakcije Fischer-Tropscheve sinteze. Rezultati kažejo, da temperatura, sestava vtoka in tlak občutno vplivajo na selektivnost in količino produktov. Študija predstavlja pomemben prispevek k boljšemu razumevanju Fischer-Tropschevega procesa, saj ponuja podrobno analizo vpliva različnih parametrov na reakcijski sistem. Poleg tega kinetični model, implementiran v dveh različnih programskih okoljih, predstavlja koristno orodje za nadaljnje študije in optimizacijo procesa Fischer-Tropsch. In this master thesis, we focused on the study and modelling of the high temperature Fischer-Tropsch process, with an emphasis on understanding the process conditions, the role of catalysts, and the chemical reaction mechanisms. Fischer-Tropsch synthesis is a chemical process for converting syngas, a mixture of carbon monoxide and hydrogen, into hydrocarbons. The central part of our work was the development of a kinetic model and its implementation in the Aspen Plus and CRUISETM M programs. The main objective of the study was to investigate and compare the results of the two programs, to observe the influence of parameters such as temperature, feed composition, and pressure on the metabolism of the reactants and the production of the products, and to study the effects of discretization in CRUISETM M. The results of the analysis show differences in the calculated values between the two programs. In Aspen Plus, a higher metabolism of the reactants or a higher mass flow of saturated and unsaturated hydrocarbons was observed. In both simulations, the largest mass fraction of pentane was observed among the products. In the following, we compare the results with the literature, with a particular focus on the analysis of the parameter α (chain growth probability), which influences the distribution of hydrocarbons at the reactor outlet. The study also investigated the influence of various factors such as temperature, feed composition and pressure on the results of the Fischer-Tropsch synthesis reaction. The results show that temperature, feed composition and pressure significantly affect the selectivity and the amount of products. The study represents an important contribution to a better understanding of the Fischer-Tropsch process, as it provides a detailed analysis of the influence of various parameters on the reaction system. Furthermore, the kinetic model implemented in two different software environments represents a useful tool for further studies and optimization of the Fischer-Tropsch process.
