Ethylene oxide is an important ethylene baA Simulation Model of a reactor for Ethylene Oxide productionbyHanna PerzonDepartment of Chemical EngineeringLund University42156Supervisor: Assoc. Pr product EO by shell ne’s.In the production of ethylene oxide, ethylene and oxygen reacts over a silver catalyst surface. Mainly two reactions occur, partial oxidation of ethylene to ethylene oxide and total oxidation of ethylene to carbon dioxide and water. The largest cost in production of ethylene oxide is ethylene t product EO by shell herefore it’s important to optimize the selectivity towards ethylene oxide and thus reduce the consumption of ethylene.Tire aim with this thesis was tproduct EO by shell

It is agreed that silver can adsorb oxygen in a number of ways and that this phenomenon is the basis of silver’s efficiency in catalyzing the oxidation of ethylene to ethylene oxide. product EO by shell A Simulation Model of a reactor for Ethylene Oxide productionbyHanna PerzonDepartment of Chemical EngineeringLund University42156Supervisor: Assoc.
