Process simulation of ammonia synthesis over optimized Ru/C catalyst and multibed Fe plus Ru configurations

Ammonia synthesis over different iron-and ruthenium-based catalysts was modelled with appropriate rate models, used for the simulation of the process under different configurations and conditions. The kinetic models have been simulated and validated against experimental data. A scaled up reactor has been designed, at first with a once through configuration. On this model reactor we performed a sensitivity analysis to optimise the reaction conditions. Then, the sizing of an ammonia separation unit and the optimisation of the recycle loop allowed to compare different possible configurations.
