modeling of ammonia three bed synthesis reactor

In this study, the heterogeneous modeling of the ammonia synthesis reactor is presented# nitrogen and hydrogen gases react to produce ammonia through an exothermic reaction at high temperature and pressure# the ammonia synthesis reactor has several types in which the three-bed type is modeled with acceptable error# the rate of conversion of the nitrogen and the output temperature of the reactor reached 22#6% and 716#77 k respectively# finally, using sensitivity analysis, the effect of input parameters such as temperature and velocity on the output conversion was investigated# the conversion decreased with increasing velocity and since the ammonia production is equilibrium and exothermic reaction at a certain temperature, the conversion of nitrogen reached a maximum#
