Abstract:V diplomskem delu smo raziskovali reakcijo epoksidacije etilena na srebrovih katalizatorjih. Epoksidacija etilena je komercialno ena najpomembnejših selektivnih oksidacijskih reakcij. Etilen epoksid je vsestransko uporabna kemikalija, ki se neposredno uporablja za sterilizacijo in dezinfekcijo, kot fungicid, še pogosteje pa kot surovina za pridobivanje drugih spojin (etilen glikol, detergenti, etanolamini, itd.). Navadno ga pridobivamo kot produkt nadzorovane oksidacije etilena s kisikom na srebrovem katalizatorju, saj ta ne prekine vezi med vodikom in ogljikom, kar bi vodilo v reakcijo gorenja. Katalizatorju pogosto dodamo cezij, klor, baker ali žlahtne kovine in s tem povečamo njegovo selektivnost. V tem diplomskem delu s pomočjo matematičnega modela v programskem jeziku Python raziskujemo, kako različni pogoji vplivajo na hitrost reakcije in njeno selektivnost na različnih srebrovih katalizatorjih. Zanima nas, kako se spreminja selektivnost, katera temperatura je najugodnejša, kateri tlak izberemo za najoptimalnejši potek reakcije in kateri naj bo katalizator.

Title:Kinetic modelling of ethylene epoxidation on silver catalysts
Abstract:In this work, we studied the epoxidation reaction of ethylene on silver catalysts. Commercially, the epoxidation of ethylene is one of the most important selective oxidation reactions. Ethylene epoxide is a versatile chemical used directly for sterilisation and disinfection, as a fungicide, and more commonly as a raw material for the production of other compounds (ethylene glycol, detergents, ethanolamines, etc.). It is usually obtained as a product of the controlled oxidation of ethylene with oxygen on a silver catalyst, since it does not break the hydrogen-carbon bond, which would lead to a combustion reaction. Often cesium, chlorine, copper or noble metals are added to the catalyst to increase its selectivity. In this work, we use a mathematical model in Python to investigate how different conditions affect the reaction rate and selectivity on different silver catalysts. We are interested in how selectivity varies, what temperature is most favourable, what pressure to choose for optimal reaction, and which catalyst to use.
