Abstract Methanol is very commonly used as a feedstock in the chemical industries. It is also used as fuel and as a solvent. The catalysts are used and widely studied in this field. Nowadays, one of the main interests is the use of CO2 as a feedstock in methanol synthesis. Even though methanol has been produced commercially since 1923, the reaction mechanism and kinetics are still an open question. This report presents a short literature review of methanol synthesis and its kinetics and modelling. The simulator is developed based on the mass balances and kinetic models from the literature. The simulator is used to evaluate the steady-state and dynamic behaviour of the process. For the selected model, the information about the importance of model parameters are studied through sensitivity analysis.
