ABSTRACT:

Simulation of an auto-thermal ammonia synthesis reactor is our task in this paper. We are

interested mainly in determining the length of the reactor which has a great impact on ammonia

yield. There are many literatures that are interested in Ammonia synthesis reactor but all need

some corrections due to either uncorrected model used, or uncorrected algorithm. We solved it

with the aid of MatLab built in function ODE45 solver in addition to simulated annealing

algorithm (SA) and solved for every 0.0001 m from the reactor length. It is found that no spikes,

no reverse reaction can take place even at higher top temperature of 800 K. the maximum value

of ammonia objective is 5.6635e+006 at optimal reactor length of 6.4253 m.
